While in cruise flight, the engine began making banging and hissing sounds, emitting white smoke, and steadily losing power. The pilot requested vectors from ATC to the nearest airport, Dobbins ARB, but couldn't stretch his glide, and made a forced landing onto a construction site. The airplane came to a stop in trees and was destroyed. An NTSB-supervised teardown inspection revealed failure of the oil cooler core resulting in oil starvation.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

A catastrophic failure of the oil cooler core which led to overboard porting of lubricating oil and subsequent engine failure.
