The Nigerian Safety Investigation Bureau (NSIB) has recommended to the Nigerian Civil Aviation Authority (NCAA) the need to carry out inspection on all Allied Air airplanes for potential mechanical and structural vulnerabilities, specifically focusing on the flap and landing gear systems.
The NSIB’s recommendation is contained in the
preliminary report on its ongoing investigation into the incident involving a Boeing 737-400 Freighter aircraft, with registration marks 5N-JRT, operated by Allied Air Limited.
This is just as a statement signed by the NSIB’s Director, Public Affairs and Family Assistance, Mrs. Bimbo Oladeji, assured that further investigation into the incident will focus on a detailed inspection of the right main landing gear assembly, testing and examination of the aircraft’s flap drive system components, including transmission assemblies and actuators
She also said that further analysis on the main wheel tyres for any indications of failure or wear will also be carried out

A loud bang was reported from the right side upon touchdown. The right main landing gear assembly detached, causing the No. 2 engine nacelle to drag along the runway for approximately 1172 meters before the aircraft veered off the runway. The aircraft came to rest on the grass verge, facing 170 degrees from the runway heading,” NSIB Report revealed.
The Report further revealed that the right main landing gear was found sheared off from its attachment point while the No. 3 and No. 4 main wheel tyres burst and that damage was observed on the No. 2 engine nacelle and lower right-wing section.
The Report also said informed that the structural integrity of the cabin and cockpit remained intact and that all the occupants on board the aircraft exited safely through the forward main door without injuries.

The aircraft had a valid Certificate of Airworthiness and had performed 101 landings since November 1, 2024, 85 of which used Flaps 15. Weather conditions were favourable with no adverse meteorological factors reported. All navigational and communication equipment, except the Airfield Lighting Panel System, were serviceable.”
