By Dickson Omobola Nigerian Safety Investigation Bureau, NSIB, has disclosed that the flight crew of a Bombardier Challenger 604 aircraft, with nationality and registration marks T7-SEI, operated by Triton Aviation Limited, observed an abnormal increase in cabin altitude and suspected a pressurisation issue at 17:19, before its passenger-crew door detached during initial climb.
NSIB also revealed that the cabin crew’s medical certificate was not valid at the time of that occurrence.
Recall that on October 15, 2026, the serious incident occurred after the aircraft took-off from Nnamdi Azikiwe International Airport, Abuja. The aircraft, operating as DWC052, was conducting a non-scheduled flight from Abuja to Murtala Muhammed International Airport, Lagos, with nine persons on board, comprising two flight crew members, one cabin crew member and six passengers. NSIB, in its preliminary report, stated that the captain subsequently instructed the cabin crew to double-check the main cabin door, adding that as the cabin crew approached the passenger-crew door to carry out the inspection, the door opened and subsequently detached from the aircraft. Director-General/Chief Executive Officer of NSIB, Captain Alex Badeh Jr, who signed the report, stated that the flight crew subsequently declared an emergency and coordinated with Abuja Air Traffic Control, ATC, for an immediate return to the airport.
