The Nigeria Safety Investigation Bureau has revealed that the door of a private jet with registration number T7-SEI and flight identification DWC052, which detached from the aircraft mid-air in October, actually flew open when a crew member attempted to recheck whether it was properly closed, following an instruction from the pilot.

This was contained in a preliminary report released by the Nigerian Safety Investigation Bureau on Thursday, which detailed how the flight crew scrambled to manage the situation and declared an emergency.

Recall that the aircraft, which was headed to Lagos from Abuja, was forced to declare emergency and immediately engaged in an air returned before landing at the Abuja airport.

In a video sighted by The PUNCH, the separated door, was reportedly recovered by farmers from a farm in the Abuja area.

According to the report, trouble began during the aircraft’s initial climb when the Pilot Monitoring observed an unusually rapid increase in cabin altitude at approximately 4,000 feet per minute.

Suspecting a pressurisation problem, the captain instructed the pilot to reduce the aircraft’s rate of climb in an attempt to address the situation.

According to the report, the development caused the pilot to suspect that the aircraft door may not be properly closed.

The reported further noted that “At about 17:19:07, the captain instructed the cabin crew to double-check the door,” warning that the cabin altitude increase was unusually high.

The cabin crew member initially inspected the Passenger-crew Door from her seated position and reported that it appeared to be properly closed, with the green indicator band aligned.
