What happened
The incident occurred while the aircraft was engaged in an aerial line patrol flight. During this phase of operations, the pilot encountered low stratus cloud conditions. In response to the deteriorating weather, the decision was made to return to Billard Airport.
While en route back to the airport, the engine ceased to operate. The pilot immediately attempted to restart the aircraft's powerplant but was unable to do so. With no power available, a forced landing was executed into a mowed pasture meadow. The aircraft came to rest in a ravine following the impact.
The investigation
The investigation focused on the mechanical status of the aircraft and the circumstances surrounding the engine failure. Examination revealed that the engine had stopped operating during the return flight. Subsequent attempts by the pilot to restart the engine were unsuccessful, confirming a loss of power that necessitated the off-airport landing.
Findings
The primary factor leading to the incident was the cessation of engine operation during the return leg of the patrol. The inability to restart the engine left the pilot with no option but to perform a forced landing in unprepared terrain. The presence of low stratus clouds contributed to the decision to abort the patrol and return, placing the aircraft in a situation where an immediate landing was required.
