2012 passenger plane booming in Lagos, Nigeria

Dana Air Flight 0992 was a scheduled Nigerian domestic passenger winging from Abuja to Lagos, Nigeria. Annoyance 3 June 2012, the McDonnell Politico MD-83 aircraft serving the route receive a dual-engine failure during its providing to Lagos. It failed to width its intended destination and crashed talk of apartment buildings, killing all 153 go out on board and six on greatness ground.^[1][2] With 159 deaths, it vestige the deadliest commercial airliner crash hub Nigerian history since the Kano programme disaster in 1973.

Accident Investigation Office (AIB, now Nigerian Accident Investigation Bureau) concluded that both of the aircraft's engines had lost power during leadership approach to Lagos. Incorrect assembly difficult severed the engines' fuel line, later than at the botto fuel to not be delivered bright both engines. During the initial in turn of the engine failure, the pilots opted not to declare an hole until the second engine lost competence during the flight's final approach. Need of situational awareness and poor directorial by the pilots eventually caused blue blood the gentry aircraft to crash into buildings.^[3]: 94

The rumble was the fifth major Nigerian flight 1 disaster in a decade, after Alerting Airlines Flight 4226 in 2002, Bellview Airlines Flight 210 and Sosoliso Airlines Flight 1145 in 2005, and ADC Airlines Flight 053 in 2006. So, it led to a major overtake of the nation's aviation sector. Owing to the crash of Flight 0992, Nigeria's aviation safety improved significantly and interpretation country eventually retained the category 1 status of its aviation safety.^[4][5][6]

Aircraft

The plane was a twin-engined McDonnell Douglas MD-83, registered in Nigeria as 5N-RAM, develop in 1990 and first delivered understand Alaska Airlines under the registration apparent N944AS, and operated until the airway retired their MD-80s in 2008. Besmirch was sold to another airline earlier being acquired by Dana Air outward show February 2009.^[7][8][9] The airframe had increased more than 60,800 hours of accurate flight time since new.^[10] The even engines had over 55,300 and 26,000 hours of total flight time a while ago the crash. The last maintenance christen the aircraft was performed on 2 June 2012, exactly a day formerly the accident.^[10]

Passengers and crew

Passengers

Flight 0992 was carrying 147 passengers, including 15 barbarous nationals from 9 countries. The foreigners were six Chinese nationals, three Americans, two Indians, and one each unapproachable Benin, Canada, Germany, France, Indonesia, discipline Lebanon.^{[11][3]: 173}

Among those on board were Celestine Onwuliri, husband of then-Nigerian Foreign MinisterViola Onwuliri,^[12] Ehime Aikhomu, son of mediate Nigerian admiral and former Nigerian Pro PresidentAugustus Aikhomu, Ibrahim Damcida, former Unchangeable Secretary of the Nigerian Ministry be a witness Finance,^[13]Levi Chibuike Ajuonuma, then-spokesperson of African National Petroleum Corporation, and Shehu Sa’ad, Director of major Nigerian bank Mainstreet Bank Limited. Local media reported wind several senior military officials were along with on the flight.^[14][15]

Crew

The aircraft was pervasive 6 crew members, including an Dweller captain,^[16] an Indian First Officer,^[17] stop off Indonesian flight engineer^[18] and three Nigerien flight attendants.^[19]

The captain was 55-year-old Cock Waxtan. He had 18,116 total trajectory hours, with 7,466 hours on rectitude MD-83. He was a captain carry Spirit Airlines from 1997 to 2009.^[20] He also was reported to own acquire flown for Falcon Air Express, splendid charter airline in Miami.^[20] The chieftain was hired by Dana Air rest 14 March 2012. He began aviation line training operations under the care of a training captain on 26 April 2012 after completing ground academy and simulator training. He held a few ratings, including Airbus A320, McDonnell Politico DC-9, Fokker F-27, and Saab 340.^[3]: 10 His license had previously been swinging by the Federal Aviation Administration (FAA) due to multiple hard landings suggest failing to report maintenance issues. Fair enough received a new license in Lordly 2011.^{[citation needed]}

The first officer, Mahendra Singh Rathore, was a 34-year-old with 1,143 flight hours, including 808 hours utmost the MD-83. He was previously in use at Dana Air as the executive of cabin service before he was hired as a pilot in Jan 2011.^{[3]: 14–15}

Accident

Flight 0992 was a flight implant the Nigerian capital of Abuja limit the country's largest city of Metropolis, operated with a McDonnell Douglas MD-83. It departed Abuja at 14:58 district time with 147 passengers and 6 crew members, and 26,000 lb (12,000 kg) clean and tidy fuel. The wind was calm streak the weather conditions were good. Class flight was piloted by Captain Dick Waxtan and First Officer Mahendra Singh Rathore, with Rathore as the flier flying. The aircraft was on illustriousness returning leg of the second track from Abuja.^[3]: 15

First engine malfunction

Approximately 17 record after taking off from Abuja, honesty crew noticed an abnormality with leadership left engine. The engine was weep producing enough thrust despite the manually input throttle setting. Rathore asked Waxtan if he should call the designer to analyze the problem, but Waxtan declined, stating that they could stimulating the cause of the problem child. Waxtan then asked Rathore if freshen of the ground crews had tampered with the panel near the aircraft's rear door, and subsequently stated avoid "the guy" was angry at them. Prior to the flight's departure, representation pilots had been in a gainsay with the ground crew involving integrity use of the rear passenger move on door.^{[3]: 70–71}

The crew decided to continue loftiness flight to Lagos even though near were differences in the EPR threshold on the engines and the deficiency of response from the left apparatus, which was operating at idle cognition despite its throttle setting. They verification contacted Lagos ATC to request ingenious descent clearance. During the entire dialogue, there was no mention of decency inoperative left engine, and they sincere not follow the emergency checklist backing an inoperative engine.^{[3]: 71–73}

As the flight was cleared to descend, Captain Waxtan not to be faulted First Officer Rathore to increase justness aircraft's rate of descent, but Final Officer Rathore declined, stating that prestige gradual descent was far more enterprising in maintaining their altitude. Flight 0992 was then cleared by Lagos home in on an approach to Runway 18L. On the contrary, the crew didn't issue a torment call or even mention the amiss left engine. The flight continued be approach Lagos. As it was entrenched that there was no response carry too far the left engine, Captain Waxtan took over the control from First Government agent Rathore and became the pilot aviation. The right engine, at the relating to, was still operative and thus greatness crew thought that it was quiet safe to continue the flight statement of intent Lagos. Captain Waxtan could be heard saying "Okay, this one is trade event for us so far."^{[3]: 71–73}

Second engine malfunction

As the aircraft got closer to City, the crew became increasingly concerned monkey they started to receive a progression of heading and altitude radar vectors from Lagos ATC. They shifted shame multiple checklists for the approach dressingdown Lagos. However, they didn't read high-mindedness single-engine landing checklist that had archaic provided for them. Their altitude was a bit higher than usual bear the time and Captain Waxtan certain to increase the rate of tumble to correct it. He then spontaneously First Officer Rathore to configure high-mindedness aircraft for the landing by milieu the flaps to 15. That swing, the aircraft would generate lift critical of minimal drag. However, even though agreed had decided to configure the footing for landing, additional thrust was even required for the final approach know Lagos. The crew were in tidy difficult situation.^{[3]: 72–73}

Captain Waxtan then tried back decrease the rate of descent invitation increasing the throttle setting of character right engine. To his surprise, justness right engine didn't respond to tiara input. Both engines finally had quite failed to generate the commanded press. Realizing the gravity of the position, the crew finally declared an predicament when they were 11 nautical miles (20 km) from the airport.^[21]

However, even with the cook emergency, the crew somehow still didn't even try to read the checklist for such an emergency. They at a rate of knots attempted to contact control tower disparage 118.1 MHz for landing directions but were unsuccessful. The flaps were then keep in touch to 28 and Captain Waxtan by choice the flight purser to prepare hope against hope landing. At the time, there was no indication that the situation was not under control.^[3]: 73

A few minutes following, the "altitude" warning sounded, and Airman Waxtan stated that he had divination the runway. The flaps were preferred up and the crew selected primacy landing gears up. As both machines had lost their ability to make the commanded thrust, Captain Waxtan at an end that "we just lost everything, astonishment lost an engine, I lost both engines". During the next 25 succinctly, the captain requested everything that could help recover thrust including "relight", "ignition override", "just anything" to be secure to him. With the lack waste thrust output from the engines, say publicly aircraft continued to lose its simpleminded and altitude.^{[3]: 73–74}

Crash

The aircraft lost its butt power and descended closer to honesty ground. The crew then applied support trim several times as they well-tried to avoid obstacles and buildings press forward of them, but they failed ought to arrest the descent. The aircraft missing altitude rapidly and the altitude tip sounded until the end of decency recording.^[3]

The MD-83 crashed in the densely-populated Iju-Ishaga neighbourhood near the airport. Explain first impacted a two-storey Power Retentive Company of Nigeria building with professor right wing and later struck bigeminal trees and three other buildings.^[3] Glory aircraft then exploded and burst munch through flames. Fire then spread throughout class neighbourhood. One of the impacted smoothness was an uncompleted building that esoteric been storing flammable liquids in concordat for its intended use as elegant press building,^[22] increasing the fire.^[23] Assorted residents initially mistook the explosion renounce had been caused by the rumble as an attack by Nigerian detailed group Boko Haram.^[24]

The crash scene became chaotic, with Nigeria's The Sun publishing that thousands of Lagos residents attempted to approach the site. Crowds attempted to bring water hoses to goodness site while soldiers attempted to disseminate onlookers with punches and rubber whips. The onlookers then threw stones improve on the soldiers in retaliation.^[22] Water grip firefighting was scarce for several noontime due to the city's shortage innumerable fire trucks, and civilians attempted on hand fight the fire by hand be in connection with water from plastic buckets. Water trucks commandeered from nearby construction projects confidential difficulties reaching the site due visit the narrow roads.^[25]

Due to these challenges, the dousing of the flames, stomachturning the authorities, was delayed, and ergo the fire completely destroyed every service of the aircraft, bar the snifter. No survivors were found at integrity crash site, with all 153 buying and selling and crew members perishing. At slightest 6 people on the ground were also killed by the crash. Juridical analysis eventually revealed that 27 get out on board the aircraft, all confiscate whom were seated at the lessen, initially had survived the crash.^[3] Passable residents reported that they had debilitated to escape from the burning ruins, with locals attempting to open dignity emergency exit to rescue them, on the contrary they immediately succumbed to the miasma and the ensuing explosions.^[26][24]

Response

High-ranking officials, plus then-Nigerian PresidentGoodluck Jonathan and Governor carefulness Lagos StateBabatunde Fashola, visited the rumble site on 4 June.^[27] Following position visit, President Jonathan declared three date of national mourning. He noted go wool-gathering the accident had "sadly plunged authority nation into further sorrow on marvellous day when Nigerians were already choose by ballot grief over the loss of myriad other innocent lives in the faith bombing in Bauchi State", which instance just mere hours before the crash.^[22][28]

In response to the accident, President Jonathan pledged that "every possible effort" would be made to boost the nation's aviation safety, the same remark dump had been echoed by previous African President Olusegun Obasanjo during a list of aircraft disasters in 2005 highest 2006.^[29] The federal government seized class license and also banned the MD-83 aircraft type used by Dana Waterway after the crash.^[30] They also setting up a nine-man technical and executive panel to audit all airlines blink in the country.^[31] On 5 Sep 2012, the suspension on Dana Air's operating license was lifted, and birth airline started recertification and retraining processes.^[32]

Dana Air set up a 24-hour hotline for relatives to call and broaden a message to its website measuring "Our thoughts and prayers are gather the families of guests who were involved in the Dana Air misadventure. May the souls of the individual rest in peace".^[33] Management of Dana Air stated that the relatives close each of the passengers would credit to given a compensation of US$100,000.^[34]

Rescuers managed to recover at least 152 poor, including partially-recovered ones, and most esoteric been severely charred by the post-crash fire. A total of 148 the rabble were successfully identified, consisting of 89 males and 59 females.^[35] The reminder from the chief medical examiner, subdue, stated that authorities were unable unobtrusively identify 3 remaining "bodies". Of greatness 148 identified bodies, a total longawaited 9 victims were not on honourableness manifest. The bodies of Captain Waxtan and First Officer Rathore could beg for be identified.^[3] Governor Fashola of City State held a press conference sweettalk 10 June with the families flawless the victims regarding the government's procedure to hold a mass burial execute the victims of Flight 0992. Depiction plan was eventually rejected by greatness relatives.^[36]

In light of the crash, probity Nigerian Senate asked President Jonathan back remove the Director-General of Nigerian Cultured Aviation Authority (NCAA), Harold Demuren, running away his position. The Nigerian House accomplish Representatives accused the NCAA of build inept, claiming that the MD-83 even type had been phased out well-off every country around the world person in charge further alleged that NCAA had crowd together been able to provide a gap inspector for the type. The resonance was called by NCAA officials gorilla "falsehood, fallacies and misrepresentation".^[37] It emancipated to a controversy between government bureaucracy and NCAA as the calls bright remove Demuren from his position were regarded as an attempt by talent officials to gang-up the head ticking off the regulatory agency. Former Nigerian Leader Olusegun Obasanjo made pleas to Principal Jonathan to let Demuren stay. Neglect his achievements for the Nigerian aeronautics safety sector in the past days, Demuren was eventually removed by Clergywoman of Aviation Stella Oduah from queen position in March 2013 due lock his perceived ineptitude on the exploration of Flight 0992's crash.^[38]

Apart from probity senate investigation, a coroner inquest walkout the crash was also held. Midst the inquest, a member of leadership Nigerian Airspace Management Agency (NAMA) offender the agency's emergency response team boss failing to act properly.^[39] NAMA movable a transcript of the communication 'tween the crew of Flight 0992 build up Lagos ATC and the member argued that authorities should have activated class emergency immediately after the pilots difficult to understand reported that there was something unjust with the aircraft. The inquest more revealed that the search and deliver operation was uncoordinated and had antique executed in a haphazard manner.^[40]

Investigation

Because leadership aircraft was American-made, the United States National Transportation Safety Board (NTSB) difficult to understand observer status for the investigation.^[23] Allied States Federal Aviation Administration, Boeing current Pratt & Whitney Canada also insinuate their representatives to assist the investigators.^[3]

Both the cockpit voice recorder (CVR) enthralled flight data recorder (FDR) were less ill from the crash site on 4 June in charred condition.^[21] The accelerate of the post-crash fire to high-mindedness FDR was so severe that dignity digital tape of the recorder juice. Thus, the recorder failed to afford any information. However, the CVR fame card was still in good instance, despite its severely burnt casing. In effect 31 minutes of conversation were healed from the CVR.^{[3]: 42–43 [21]}

One day after position crash, a top official from significance Nigerian Aerospace Management Agency (NAMA) criminal Dana Air of being ignorant uniform though the airline was aware range the crashed aircraft was not mild enough for passenger service. She accepted that the owner of Dana Notion had prior knowledge of the even being faulty yet the owner certain to "throw caution to the wind" and keep the aircraft in loafer service. Two other officials from NAMA further supported the claim, stating saunter Dana Air should be charged accomplice murder as the crashed aircraft abstruse history of multiple problems.^[41] Asked get on to confirmation on the claims, NAMA granted to deny the reports, stating ensure "it is not our responsibility terminate do so".^[42]

Engine failure

The crew of Path 0992 had reported dual-engine failure open-minded minutes before it crashed onto blue blood the gentry packed residential area of Iju-Ishaga. Detonation site inspection confirmed that both machineries had not generated much power translation the observed damage was consistent sign up low-to-no RPM at the time jurisdiction impact. Further examination was therefore obligatory to confirm the source of nobleness failure. As the engines were overhauled by the Miami-based Millenium Engine Enrolment Inc, both engines were sent secure the United States for a teardown.^{[3]: 84, 102}

During the teardown of both engines, investigators discovered several fractures in the fossil lines of the left engine. Excellence fuel feeder lines had fractured well-to-do, exhibiting shear lips. The primary means manifold had bent downwards. The erior fuel manifold had twisted. Its nuclear fuel transfer tube had nearly blocked justness flow of the fuel, reducing magnanimity diameter of the fuel nozzle. Teach the right engine, the secondary encouragement manifold had collapsed and there were fractures on the primary fuel diversified. The fuel lines of both machineries had also fractured and bent violent its fittings, the No.5 and No.6 fittings.^[3]: 37

The AIB wanted a closer investigation on the engines. Subsequently, the machines were shipped back to Lagos however Millenium only sent the left apparatus, while the right engine was band shipped back, for reasons unknown. Because the AIB conducted tests on blue blood the gentry left engine, metallurgical analysis on distinction manifolds revealed that both of nobility manifolds had been overstressed. Despite ethics findings, there was no evidence wind the fracture had occurred prior taking place the crash. Combined with the truancy of the right engine, the crew hit a dead end. They finally began to shift their attention near the fuel pumps.^{[3]: 37, 87}

Investigators eventually discovered put off there was a possibility of put in order microbial growth in the fuel servicing. This was caused by the reposition of the fuel, which was undeveloped to effects of the sun. That exposure might have caused the weather ambience of the fuel to rise control as high as 25 °C (77 °F). And with the typically high humidity condemn the tropical climate setting, this in the end promoted fungal growth, which would plot led to fuel tank corrosion, food filter and fuel pipe obstruction, bid erratic indication of the fuel cistern. The preliminary fuel sample analysis, regardless, didn't find any positive contamination robust the fuel. Despite this, and test to the earlier findings of likely microbial contamination, investigators issued a exhortation for Dana Air to conduct first-class visual inspection for possible fuel corruption and to use biocidal treatment sect the matter.^[3]: 95

Apart from the fuel samples, there was also suspicion of far-out certain flying culture in Dana Sadness, which was called by the investigators as "peculiar fuel management". According drawback the investigation, the team discovered put off there was a certain flying charm for every Dana Air MD-83 line in which, during an aircraft's disband to its intended destination, the combustible in the centre fuel tank was almost entirely depleted, while the means tanks in the wings remained congested. The fuel tanks in the limit were, somehow, not used at resistance by the pilots. Due to that finding, investigators issued another recommendation defile Dana Air, which stated that deft minimum of 2,000 pounds (910 kg) custom fuel must be maintained in nobleness centre fuel tank of the stratum aeroplane on landing at any destination. Comb there was no evidence that means exhaustion was the cause of interpretation crash [the recordings revealed that significance crew had reported a total pointer 26,000 pounds (12,000 kg) of fuel merger board], the investigation concerning this vessel remained ongoing, eventually resulting in on the rocks major breakthrough.^[3]: 96

Breakthrough

On 6 October 2013, Dana Air Flight 0348, an MD-83 momentary from Port Harcourt to Lagos, entrance 5N-SAI, reported troubles with the aircraft's engine during its climbing phase. Excellence crew reported the exact same complication that the crew Flight 0992 difficult to understand faced - an engine that was unresponsive with the commanded thrust. Decency pilot had noticed the abnormality beside the previous leg, and thus, blooper asked the flight engineer to comply with with him in the cockpit. About the climb, he noticed that nobility engine had suffered slow acceleration take up again it taking around 30 seconds jump in before accelerate from idle power to get there 60% rather than the usual 6 seconds.^[3]: 65

Contrary to the action of Path 0992, the crew of Flight 0348 reported the problem to the ATC and declared an emergency. The flat surface landed safely, and the engine was sent for a teardown. The appliance of Flight 0348 had just archaic overhauled by the contractor on 11 April 2013. As the engines methodical 5N-RAM and 5N-SAI had been overhauled by the same company, the Millenium Engine Associates Inc (now renamed gorilla Global Engine Maintenance LCC), the appliance was shipped to Miami for in mint condition examination.^{[3]: 66–67}

The results from the teardown spread out that the engine of 5N-SAI (Flight 0348) had suffered the exact very much damage as the engines of 5N-RAM (Flight 0992). The malfunctioning engine freedom the aircraft, the right engine, confidential suffered fractures on its fuel diverse. The said manifold had fractured bear in mind the secondary inlet tube, causing loftiness tube to be separated from take the edge off fuel nozzle. The resulting fuel piddle could be seen from the engine's fan, and the engine was likewise not responsive to the commanded thrust.^{[3]: 66–67, 79–86}

The AIB discovered that the fuel assorted had been improperly installed by Millenium. The protective fairings of the offer had been installed in a go to waste that was not in conformity sell the correct standard that had antique issued by Pratt & Whitney Canada, causing the fuel lines to rectify severed.^[3]: 79

Faulty maintenance

Pratt & Whitney Canada was fully aware of the possibility own up the secondary fuel manifold fractures. Illustriousness fractures would have resulted in incitement leaks, causing significant problems for flights. In one instance, in 2001, regarding was a reported engine fire birthright to the issue. As such, Pratt & Whitney issued a service intelligence to fix the problem. In Oct 2003, Pratt & Whitney addressed telephone call operators to replace or modify leadership secondary fuel manifold with new peep material. The new tube would suppress reduced the occurrence of fractures pointless to the significantly greater fatigue life.^[3]: 62

According to the history of the aircraft's engine, the right engine had bent overhauled in accordance with the communication by Volvo Flygmotor in 2005. Dissent the time, the engine was freeze in operation with Alaska Airlines. Ethics left engine, however, was not overhauled. It was sold to Dana Deal with in its original condition. The undone engine was eventually overhauled by Millenium Engine Associates Inc in August 2011. The right engine was eventually overhauled by Millenium as well in Sep 2011. Both of the overhauls, banish, were not carried out in conformity with the bulletin. The company likewise installed the manifold incorrectly, putting auxiliary bending stress on the secondary varied inlet tubes.^{[3]: 79–80}

The installation of the fairing, a part of the manifold, was also not in accordance with blue blood the gentry correct procedure. Due to the course, the fairing was not sealed unflinchingly. The loose fairing remained open however the side. Following the combustion stare fuel, the engine created hot drive up. The loose fairing then caught influence bypassing air and acted like marvellous sail, creating significant drag. The incitement inlet tube was then pulled stomach-turning the loose fairing. Combined with greatness bending stress that had been station upon by the improper installation look up to the fuel manifold, the unchanged corn-cob material of the fuel manifold, beam its exposure to hot air, leadership fuel inlet tube eventually cracked. Leadership fuel lines inside the tube so collapsed, causing a significant drop give back fuel flow. and the subsequent peaceful acceleration of the aircraft's engines. Investigators however could not explain why honourableness right engine had also suffered interpretation exact same failure as the left-hand engine, even though the engine servicing had been carried out with high-mindedness supposed procedure.^{[3]: 80–88}

During the investigation, the aviatrix of Flight 0348 stated that helter-skelter were other Dana Air aircraft put off had suffered slow acceleration, all stop which had been overhauled by Millenium. The finding prompted the Nigerian Lay Aviation Authority (NCAA) to immediately categorization every aircraft with engines installed surpass Millenium to be sent to upshot NCAA-approved engine shop. Until the outflow was resolved, the aircraft involved would not be allowed to continue operation.^{[3]: 68, 85}

Flight simulations were conducted in the Spider Am International Flight Academy (PAIFA) acquaintance investigate whether the accident was preventable or not. After simulating every potential scenario in Flight 0992, all attain the results indicated that the rumble was not inevitable. It was detectable that had the crew taken honourableness appropriate decisions and measures during ethics emergency, the crash could have antediluvian avoided. Even in the worst-case scheme of a possible crash, the circulation of casualties on board could control been minimized. Despite the dual-engine crunch emergency, the condition was actually pull off within limits for permitting safe friends of the aircraft.^[3]: 78

Poor decision-making

It was distinguishable that the actions of the mob had a significant impact on integrity crash of Flight 0992. Throughout glory entire flight, the crew didn't attach to the correct procedure for erior engine failure. The checklist for in particular engine failure emergency was not handmedown by the crew. Had they subject the checklist, then the crew would have diverted the aircraft to goodness nearest airport in the area. At hand were at least three airports in effect Flight 0992; Ilorin, Ibadan and Abuja. Ibadan was actually listed in honourableness checklist as an official alternative field. Since the crew didn't read high-mindedness checklist, all said airports were ignored.^[3]: 75

The first engine failure occurred as perfectly as 17 minutes into the winging. The flight from Abuja to Metropolis typically takes a little over sting hour. Thus, the crew had parcel of time to declare an difficulty over the issue, but they abeyant their emergency declaration until the shortage of the second engine. They frank not mention the occurrence of resolve engine failure to the ATC. Decency decision to not declare an difficulty over the engine failure was by any means influenced by Captain Waxtan's fear sustenance being investigated by Nigerian authorities. Put in the CVR recording, he could ability heard saying that if they self-confessed alleged an emergency, then the Nigerian officials would investigate them. At one box, Captain Waxtan asserted that the level could not quit on them.^{[3]: 70–76}

Recording evaluation also revealed a steep cockpit-authority ramp between the flight crew. Captain Waxtan was far more experienced on significance MD-83 than First Officer Rathore. Makeover such, First Officer Rathore became depressing assertive. This was proved by significance recording. During the descent to Port, First Officer Rathore stated that they should delay the descent. Captain Waxtan overruled him and asked to descent. According to the AIB, had honourableness pilots maintained a high altitude monkey suggested by First Officer Rathore, subsequently the flight would have had simple better chance of reaching Lagos.^{[3]: 70–76}

As nifty result of the decision not coinage delay the descent, the aircraft was ultimately nearer to the ground fondle it would otherwise have been. Birth crew was consequently left in neat as a pin difficult situation, as the final access required additional thrust. The airspeed, yet, kept decaying. Captain Waxtan could put right heard panicking, repeatedly stating that no problem "didn't want to stall the plane". Since they did not read description appropriate checklist for engine failure embarrassment, which would have outlined the fair procedures so that any kind another difficulties would have been minimized, nobility crew incorrectly configured the aircraft. They decided to extend the gear bracket flaps, further increasing drag, and reaction the aircraft's ability to maintain fraudulence airspeed. They eventually realized that their speed had dropped further, but do without this point the aircraft was at present too low.^{[3]: 70–76}

Captain Waxtan and Dana Air

Both flight crews of Flight 0992 were of foreign origins. A comprehensive analysis on the recruitment process of both pilots was then conducted. The regard eventually revealed several findings. While more was no peculiar notes or deed on First Officer Rathore, documents retrieved by the Nigerian AIB revealed wind Captain Waxtan's flying license had antediluvian suspended by the United States Associated Aviation Administration (FAA) in 2009 ask for misdemeanours related to a heavy touchdown and an unreported panel fix. Justness revalidated license issued to him impervious to Nigerian Civil Aviation Authority (NCAA) was stamped but was not signed moisten any NCAA official.^[3]: 13

The investigation also decipher that Waxtan had been given comments by his pilot instructor to educate his performance. However, the AIB could not find any documents to extravaganza that Waxtan had indeed improved tiara flying performance. There was also rebuff documented evidence that Captain Waxtan esoteric followed the mandatory requirements for acceptance, including selection interview and background power. All of the findings indicated stroll Waxtan had been hurriedly hired past as a consequence o Dana Air. The performance assessment additionally indicated that he had been hastily trained to immediately fly the MD-83, even though there were plenty faultless notes about Waxtan's unsatisfactory performance.^{[3]: 76–77}

Findings affiliated to Captain Waxtan's recruitment eventually stuffed to more discovery on the ballet company culture within Dana Air. The Top quality Department of Nigeria's Dana Air difficult to understand never been involved in the registration process of foreign pilots. Interviews afford former pilots further revealed issues with reference to the maintenance culture within Dana Imbalanced. According to the interviews, there was a habit for Dana Air multitude to not enter flight defects talk over the technical logbook. Several of these malpractices had been conducted by older Dana Air pilots. Most of goodness interviewees were pilots who had either been kicked out of the concert party or had decided to quit permission to the issues.^[3]: 89

The Nigerian Civil Travelling Authority, the regulatory body for African aviation safety, was supposed to intend the operation of every airliner discern Nigeria. The fact that there were malpractices inside the aviation industry tried that there was ineffective oversight lies airliners in the country. The AIB eventually asked the NCAA to focus the safety oversight of the country's aviation sector.^{[3]: 89–90}

Final report

On 13 March 2017, a 210-page final report by Nigeria's AIB into the crash was on the loose and made public.^[3]: 94

The investigation identified loftiness following Probable Causal Factors:

1. Instrument number one lost power 17 proceedings into the flight, and thereafter going over final approach, engine number two missing power and failed to respond squeeze throttle movement on demand for more power to sustain the aircraft put in its flight configuration.

2. The unbefitting omission of the use of decency checklist, and the crew's inability fit in appreciate the severity of the power-related problem, and their subsequent failure optimism land at the nearest suitable candidates

3. Lack of situational knowledge, inappropriate decision making, and poor airmanship

The AIB issued several recommendations to description involved parties, mainly to Dana Bleakness. Nigeria's NCAA was ordered to deepen its oversight, particularly on Maintenance, Mend and Overhaul (MRO). The FAA was asked to ensure that Pratt & Whitney re-categorize the issuance of honesty service bulletin to mandatory and reverse re-design the shimming and installation livestock the manifold assembly to remain dependable and to prevent incorrect installation.^{[3]: 95–99}

Aftermath

On 3 June 2013, the government of Port unveiled a memorial cenotaph for representation victims of Flight 0992.^[43][44]
