What happened
The aircraft experienced a complete loss of engine power while cruising at altitude. With no option to return to the departure airport or reach a nearby airfield, the pilot initiated a forced landing procedure. The pilot selected a highway as the most viable landing site due to its length and relative lack of obstacles compared to the surrounding terrain.
As the aircraft approached the highway for landing, smoke began to fill the cockpit, significantly reducing visibility and creating hazardous conditions for the pilot. Despite the smoke, the pilot managed to align with the road and execute a touchdown on the paved surface.
During the rollout phase, fire breached the firewall and entered the passenger compartment. The pilot immediately evacuated the aircraft while it was still in motion. The unoccupied aircraft continued its path off the highway and collided with a tree before coming to rest and burning completely.
The investigation
The investigation focused on the sequence of events leading to the engine failure and the subsequent fire. Investigators examined the wreckage to determine the point of origin for the fire and whether mechanical failure preceded the loss of power. The presence of smoke prior to touchdown suggested an issue that developed during the cruise portion of the flight.
Findings
The primary finding was the loss of engine power during cruise, which necessitated the forced landing. The subsequent fire, which originated from the engine compartment and breached the firewall, posed a critical threat to the occupants. The pilot's decision to evacuate while the aircraft was still moving was a direct response to the immediate danger posed by the fire.
Safety message
This incident highlights the importance of emergency evacuation procedures when fire is present in the cockpit or cabin. Even in a controlled forced landing, the risk of fire can escalate rapidly, requiring immediate action to ensure occupant safety.
