Investigation Summary
The aircraft was operating a multi-stop domestic round-robin route that originated at N'Dolo Airport in Kinshasa, with scheduled stops at Kiri, Bokoro, and Semendwa. During the final leg from Semendwa to Bandundu, a two-to-three-foot crocodile escaped from a bag at the rear of the cabin. The resulting stampede of 18 passengers and the flight attendant toward the front of the small, unpressurized aircraft moved the center of gravity far beyond its forward limit. The pilots, including the airline's owner Daniel Philemotte, were unable to maintain pitch control. The aircraft nosedived into a mud-brick house; while the house was occupied, no one on the ground was injured. The crocodile survived the impact but was subsequently killed by local authorities with a machete. Investigators initially suspected fuel exhaustion due to the lack of a post-impact fire, but later confirmed 150 liters of fuel remained in the tanks. While the Congolese Ministry of Transport issued a report, the lack of flight recorder data led the UK Air Accidents Investigation Branch (AAIB) and a British coroner to record an 'open verdict,' noting that the crocodile account remains technically unverified.
Final Conclusions
The Congolese Ministry of Transport investigation concluded that the crash was caused by a loss of control resulting from a sudden shift in the aircraft's center of gravity. This shift was attributed to a passenger panic caused by an escaped crocodile in the cabin. However, the UK Air Accidents Investigation Branch (AAIB), which assisted due to the death of a British First Officer, noted that without flight recorder data, these findings rely heavily on a single survivor's testimony and remain difficult to verify technically.

Systems & Failure Modes
Center of Gravity (CG)
The longitudinal point where the aircraft balances. In small aircraft like the L-410, the movement of all occupants to the front can move the CG forward of the 'limit of travel,' making the elevators ineffective at preventing a nose-down pitch.
Flight Data Recorder
The aircraft was equipped with recorders, but investigators were unable to retrieve or process the data, leading to an 'open verdict' in the British inquest.
Interesting Facts
- 01The aircraft was a 1991-built Let L-410 previously operated by the Estonian airline Airest.
- 02There was no post-impact fire, which initially led to false reports of fuel exhaustion.
- 03The crocodile was reportedly being smuggled by a passenger who intended to sell it.
- 04The airline, Filair, was on the European Union's list of banned carriers at the time of the accident.
- 05The British First Officer had previously expressed concerns about the Captain's eyesight and the lack of cabin security regarding animals.
Safety Actions & Advisories
Cabin Security Reinforcement
The accident highlighted the extreme danger of unregulated carry-on items and live animals in small commuter aircraft, though specific regulatory changes in the DRC following the event were not widely documented.
Known Controversies & Unanswered Questions
Veracity of the Crocodile Account
Reference ↗The UK AAIB and the coroner for the British First Officer described the crocodile story as 'extremely unlikely' and based on 'vague guesses' due to the lack of flight recorder data and the reliance on a single survivor's testimony.
