What happened
The airplane experienced a complete loss of engine power while airborne. In response to the emergency, the pilot initiated a controlled descent and executed a forced landing in a nearby pasture. The terrain at the landing site was uneven, which likely contributed to the nature of the impact damage.
The investigation
Following the accident, investigators conducted a post-accident examination of the aircraft's systems. A detailed inspection of the ignition system revealed significant wear on the ignition points and the cam follower assembly. This mechanical failure prevented the engine from maintaining combustion, leading to the in-flight power loss.
Findings
The primary factor contributing to the accident was the deterioration of the ignition components. The worn ignition points and cam follower assembly failed to provide the necessary spark for engine operation. Additionally, it was noted that the pilot's certificate had been revoked prior to this flight, raising questions regarding the legality of the operation, though the mechanical failure remains the direct cause of the power loss.
