NSIB Unveils Findings on Mid-Air Door Detachment from Abuja-Lagos Flight

The Nigerian Safety Investigation Bureau (NSIB) has released a preliminary report detailing the findings of its investigation into the alarming mid-air detachment of a passenger door from a Bombardier Challenger 604 aircraft during a flight from Abuja to Lagos. The incident, which occurred on October 15, involved flight DWC052 operated by Triton Aviation Limited and was carrying nine individuals, including two pilots and six passengers.

According to the NSIB, all locking mechanisms of the passenger-cabin door were discovered in the open position, a critical detail that raises serious questions about the aircraft's safety protocols. The report, published on November 11, indicated that the aircraft's door indicator displayed an 'UNLOCKED/RED' warning, while both internal and external door handles were also found in the open position. This evidence starkly contradicts the flight crew's assertion that they received no aural or visual warnings prior to the door's separation from the aircraft.

“The incident occurred at approximately 5:19 p.m. when the flight crew observed an abnormal increase in cabin altitude and suspected a pressurisation problem,”

the report stated. Furthermore, no faults or warnings related to the door were recorded in the aircraft's downloaded Maintenance Diagnostic Computer (MDC) data, suggesting that the incident may not have stemmed from mechanical failure but rather from oversight in safety measures.

The NSIB's findings underscore the importance of stringent adherence to safety protocols in aviation, especially in light of the potential risks posed to passengers and crew. As investigations continue, stakeholders in the aviation sector are urged to review safety regulations and ensure that such incidents do not recur, reinforcing public confidence in air travel across Nigeria.
