Triton Aviation CL60 Loses Door After Takeoff From Abuja, Lands Safely After Mayday Call
Why It MattersIn-flight loss of a fuselage door on a business jet is a serious incident that places airframe and door-system integrity under investigator scrutiny, with the cause still undetermined at the segment level.
What happened
A CL60 operated by Triton Aviation, registration T7-SEI and flight identification DWC052, lost a door shortly after taking off from Nnamdi Azikiwe International Airport (NAIA), Abuja, on Thursday. The crew declared a "Mayday" emergency. The aircraft was scheduled to fly from Abuja to Murtala Muhammed Airport, Lagos.
An incident report indicates the aircraft departed Runway 22 at 4:17 p.m. UTC. It was about three nautical miles from the airport, climbing through 3,000 feet, when the crew declared the emergency. The crew told air traffic controllers that a door had opened in flight, and the approach radar controller directed the aircraft back to Abuja for an emergency landing.
The airport's fire watch room and medical team were alerted and told to stand by, and fire and emergency personnel were directed to designated positions at A4 and A5. The crew asked whether controllers could confirm if the door was open; the duty controller tried to observe the aircraft with binoculars but could not establish the door's condition because of the aircraft's position. The aircraft landed safely on Runway 22 at approximately 4:34 p.m. UTC, and after landing the duty controller observed that the door was missing from the fuselage.
A viral video showed the missing door, which was said to have been recovered by farmers on farmland within Abuja. A male voice in the video, whose identity could not be established, said the farmers found it while returning from their farm. Michael Achimugu, Director of Public Affairs and Consumer Protection at the Nigeria Civil Aviation Authority (NCAA), confirmed the incident but said the agency could not comment, as it falls under the purview of the Nigerian Safety Investigation Bureau (NSIB). The NSIB also confirmed the serious incident, and a source at the bureau said investigators had been deployed to the scene and that an official statement would be issued soon.
Industry impact & what to watch
A door departing the fuselage in flight is among the more consequential structural events a business jet can experience, and it lands directly on the airframe-integrity and door-system questions that regulators and operators treat with priority. Cases like this typically turn on maintenance records, door-latching and warning systems, and how the aircraft was handled before departure, though none of those findings exist yet for this event.
The handling of the emergency is itself part of the picture: a crew that declared Mayday early, a radar controller who turned the aircraft straight back, and ground services positioned before landing. For fleets operating the same type, the investigation outcome is what would determine whether the event is treated as an isolated occurrence or prompts wider inspection attention.
The next marker is the official statement the NSIB source said would be issued soon, which would be the first authoritative account of what investigators found on the aircraft and at the scene.
