On August 22, 1995, a Navion A (registration N8513H) was involved in an aviation accident near Groveland, CA. Investigators recorded the probable cause as: fuel starvation, due to the pilot's improper positioning of the fuel selector. The lack of suitable terrain for a forced landing was a related factor. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a VFR maintenance test flight, the engine lost power shortly after departure. The pilot turned right to return to the airport but could not reach it, recalling trying to avoid a tree before impact in a wooded area.
