Summary

The descriptions of the loss of engine power and the subsequent engine surging were consistent with fuel starvation, a situation where the fuel to the engine is interrupted, although there is adequate fuel on board the aircraft.

Although the left high-pressure fuel pump failed to deliver the required pressure and fuel flow and was found leaking during subsequent testing, it would have had little effect on the development of the occurrence and its defect may have occurred during the accident sequence.

The pilot reported that he had selected inboard tanks for the flight. The investigation was unable to reconcile the pilot's reported recollection of inboard tank selection and the evidence of the remaining fuel quantities in the inboard tanks.
