Incident Overview
A positioning flight from Lyon-Satolas Airport to Le Puy-Loudes Airport ended in a crash landing after both engines failed simultaneously during the final approach. The flight was conducted at night. At an altitude of approximately 500 feet, the crew moved both propellers to fine pitch, at which point the engines lost power. The airplane stalled and came down in an open field a few hundred meters short of the runway threshold.
Injuries and Damage
Both pilots escaped with minor injuries. The aircraft sustained damage beyond repair.
Official Findings
The investigation determined that weather conditions at the time of the accident were marginal, with icing conditions present. Both engines failed due to excessive ice accumulation after the crew set the propellers to fine pitch. The crew had not activated the engine deicing systems, nor did they attempt to restart the engines. Additionally, it was reported that no antifreeze fluid was used.
