Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The pilot experienced a total loss of engine power during climb when he made his initial power reduction. The power loss was accompanied by a loud bang. A severe postaccident ground fire melted a large portion of the engine. A partial engine teardown was performed, however, it failed to reveal the cause of the power loss or the loud bang. The examination revealed that the connecting rods, crankshaft, etc., remained intact. The ground fire followed a forced lndg and noseover.
