[3]: 10  His license had previously been suspended by the Federal Aviation Administration (FAA) due to multiple hard landings and failing to report maintenance issues.

Waxtan then asked Rathore if one of the ground crews had tampered with the panel near the aircraft's rear door, and subsequently stated that "the guy" was angry at them.

Prior to the flight's departure, the pilots had been in a dispute with the ground crew involving the use of the rear passenger exit door.

Their altitude was a bit higher than usual at the time and Captain Waxtan decided to increase the rate of descent to correct it.

The crew then applied stabilizer trim several times as they tried to avoid obstacles and buildings ahead of them, but they failed to arrest the descent.

[23] Many residents initially mistook the explosion that had been caused by the crash as an attack by Nigerian terrorist group Boko Haram.

[24] The crash scene became chaotic, with Nigeria's The Sun reporting that thousands of Lagos residents attempted to approach the site.

Water trucks commandeered from nearby construction projects had difficulties reaching the site due to the narrow roads.

[25] Due to these challenges, the dousing of the flames, by the authorities, was delayed, and consequently the fire completely destroyed every structure of the aircraft, bar the tail.

Forensic analysis eventually revealed that 27 people on board the aircraft, all of whom were seated at the back, initially had survived the crash.

[3] Some residents reported that they had tried to escape from the burning wreckage, with locals attempting to open the emergency exit to rescue them, however they immediately succumbed to the smoke and the ensuing explosions.

[26][24] High-ranking officials, including then-Nigerian President Goodluck Jonathan and Governor of Lagos State Babatunde Fashola, visited the crash site on 4 June.

He noted that the accident had "sadly plunged the nation into further sorrow on a day when Nigerians were already in grief over the loss of many other innocent lives in the church bombing in Bauchi State", which happened just mere hours before the crash.

[31] On 5 September 2012, the suspension on Dana Air's operating license was lifted, and the airline started recertification and retraining processes.

[39] NAMA released a transcript of the communication between the crew of Flight 0992 and Lagos ATC and the member argued that authorities should have activated the emergency immediately after the pilots had reported that there was something wrong with the aircraft.

[40] Because the aircraft was American-made, the United States National Transportation Safety Board (NTSB) had observer status for the investigation.

[23] United States Federal Aviation Administration, Boeing and Pratt & Whitney Canada also sent their representatives to assist the investigators.

Two other officials from NAMA further supported the claim, stating that Dana Air should be charged with murder as the crashed aircraft had history of multiple problems.

Crash site inspection confirmed that both engines had not generated much power as the observed damage was consistent with low-to-no RPM at the time of impact.

[3]: 96 On 6 October 2013, Dana Air Flight 0348, an MD-83 flying from Port Harcourt to Lagos, registration 5N-SAI, reported troubles with the aircraft's engine during its climbing phase.

The protective fairings of the tube had been installed in a way that was not in conformity with the correct standard that had been issued by Pratt & Whitney Canada, causing the fuel lines to be severed.

In October 2003, Pratt & Whitney addressed all operators to replace or modify the secondary fuel manifold with new tube material.

[3]: 80–88 During the investigation, the pilot of Flight 0348 stated that there were other Dana Air aircraft that had suffered slow acceleration, all of which had been overhauled by Millenium.

The decision to not declare an emergency over the engine failure was possibly influenced by Captain Waxtan's fear of being investigated by Nigerian authorities.

According to the AIB, had the pilots maintained a high altitude as suggested by First Officer Rathore, then the flight would have had a better chance of reaching Lagos.

Since they did not read the appropriate checklist for engine failure emergency, which would have outlined the correct procedures so that any kind of difficulties would have been minimized, the crew incorrectly configured the aircraft.

There was also no documented evidence that Captain Waxtan had followed the mandatory requirements for recruitment, including selection interview and background check.

[3]: 76–77 Findings related to Captain Waxtan's recruitment eventually led to more discovery on the corporate culture within Dana Air.

The inappropriate omission of the use of the checklist, and the crew's inability to appreciate the severity of the power-related problem, and their subsequent failure to land at the nearest suitable airfield

Lack of situational awareness, inappropriate decision making, and poor airmanshipThe AIB issued several recommendations to the involved parties, mainly to Dana Air.
