What happened
During a local training mission operating out of Anchorage-Intl Airport, a single engine airplane experienced an in-flight emergency. While the pilot was on final approach, smoke began to permeate the cockpit area. As the situation progressed, the aircraft lost altitude and collided with a dirt embankment located near the runway threshold. The impact resulted in a post-crash fire that completely destroyed the airframe. Although the aircraft was lost, the pilot managed to exit the wreckage without any injuries.
Findings
Investigations into the accident identified an onboard fire of unknown origin as a primary factor. Several contributing elements were noted during the analysis of the event:
- The pilot failed to properly estimate the aircraft's speed and distance from the terrain.
- There was a delay in the decision to execute a go-around procedure.
- Issues were identified regarding the electrical system, specifically involving the generators and protective components.
- Circuit breakers tripped during the flight sequence.
