Incident Details
While in the traffic pattern for landing, the pilots observed that the left engine fuel pressure gauge indicated below normal. They activated the fuel boost pump, which restored fuel pressure to the normal range. After landing, the left engine compressor stalled several times, and subsequently the engine caught fire.
Investigation Findings
Post-accident investigation revealed that the left engine #3 fuel line had failed. Photographs of the failed component showed that the bends in the #3 fuel line had been modified for the unique installation on the accident airplane. The fuel line was discarded before further examination could be conducted.
Fuel Line Modification
The investigation noted that the bends in the #3 fuel line were altered from the original configuration to accommodate the specific installation in the accident airplane. No additional details about the modification or its origin were provided in the source material.
