What happened
During the initial climb phase following departure from Cherbourg-Maypertus Airport, the flight crew encountered significant mechanical issues involving the engines. These complications necessitated an immediate emergency descent and an attempt to land the aircraft safely.
While attempting to manage the situation, the aircraft departed from its flight path and struck the ground in an open field situated close to the airport perimeter. The impact resulted in a crash landing; however, the aircraft came to a complete stop without further movement. There were no fatalities or injuries reported among those on board during the incident.
Findings
The investigation into the mechanical failure determined that the primary factor leading to the emergency was an error in the engine's operation. Specifically, one of the propellers mistakenly auto-feathered while the aircraft was still in its early ascent, which compromised the power required for a stable climb.
