Incident Overview
During climb to cruise altitude, the engine suffered a loss of power. Unable to maintain altitude, the pilot elected to land on an access road. The landing itself was uneventful, but during the landing roll-out, the left wheel pant struck a road marker. The airplane then yawed to the left, exited the roadway, and proceeded through a barbed wire fence before coming to rest on a dirt field.
Engine Examination
An examination of the engine disclosed that the #2 piston was destroyed. The piston was not identified as being the correct one for the engine. The engine had accrued 145 hours since a major overhaul, which was performed by an A&P mechanic.
Outcome
No further details about injuries, damage extent, or other factors were provided in the investigation source.
