What happened
Shortly after takeoff, the pilot transmitted a radio message indicating that he had experienced a mechanical failure, specifically stating that he had "blown a rod." At the time of the transmission, the aircraft was approximately two miles from the airport and positioned on a right base leg for landing. The pilot subsequently informed air traffic control at the tower that he would not be able to make it back to the runway.
As the aircraft attempted to maneuver toward the airport, the left wing struck a power pole. This impact caused the aircraft to explode upon hitting the ground. There were no further details provided regarding the condition of any occupants or specific injuries in the source text.
The investigation
A post-accident examination of the aircraft's engine revealed significant internal damage. Investigators found foreign debris within the oil pump, indicating a loss of lubrication or contamination. Most critically, the number six connecting rod was found to be completely separated from the crankshaft. Additionally, the end cap associated with the connecting rod had detached.
Findings
The mechanical evidence points directly to an internal engine failure as the primary event. The separation of the connecting rod and the presence of debris in the oil pump suggest a catastrophic loss of engine function. This led to fuel exhaustion or total power loss, preventing the pilot from completing the return to the airport. The aircraft was unable to maintain flight altitude after the initial mechanical failure.
