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

During the flight, an oil-like odor was detected and oil spots appeared on the windshield. The oil pressure dropped to zero and the engine failed. During the forced landing on a highway, the left wing struck a road sign. The spar/ fuel tank ruptured and the airplane burned. The rod bolts from the 3 and 4 rods failed after loss of lubrication. The reason for the loss of lubrication could not be determined.
