On impact, the undercarriage were torn off and the airplane came to rest few dozen metres further. All nine occupants were evacuated, one passenger was slightly injured. The aircraft was written off.
Probable cause:
The accident was the consequence of a loss of speed due to abnormal use of flight controls and landing flaps. The following contributing factors were reported:
- Stall during initial climb after the pilot prematurely retracted the flaps from 28° to 14°,
- At the time of the accident, the total weight of the aircraft was 2,600 kilos, 185 kilos above the MTOW for existing flying conditions,
- There were eight passengers on board while the aircraft was certified for seven passengers maximum,
