Incident Overview
During a straight-in approach for landing, the pilot reported reducing power when the engine experienced a total loss of power. The pilot subsequently executed a power-off, gear-up forced landing in a congested area. The aircraft landed on rough, uneven terrain, causing substantial damage.
Pilot Account
The pilot stated that the engine had a total loss of power during power reduction on approach. In his written statement, he speculated that the engine may have had a vapor lock, though this was not confirmed.
Post-Incident Examination
FAA inspectors examined the aircraft after the incident. They found approximately 8 gallons of non-contaminated fuel in each fuel tank. An operational check of the engine was performed, during which the engine operated throughout normal operational limits with no abnormalities noted.
Records Review
A review of aircraft records found no discrepancies. All applicable airworthiness directives, including those pertaining to vapor lock, were noted as having been complied with.
Findings
Despite thorough inspection and operational testing, no cause for the power loss was found. The engine functioned normally under test conditions, and fuel was uncontaminated and present in adequate quantity. No mechanical or maintenance issues were identified.
