What happened
The aircraft had been out of service for two years prior to the accident. Before departure, a mechanic observed evidence of fuel leaking at the drain holes located in the left wing root, just aft of the main cabin door. This information was communicated to a pilot-rated passenger. Shortly after this observation, the aircraft departed with the pilot in command, the aircraft owner, and two passengers, one of whom was the mechanic.
Approximately 14 minutes after takeoff, radar data indicated that the aircraft transitioned from a climb into a descent while performing a 180-degree turn. During this period, witnesses observed smoke and flames trailing from the aircraft. The aircraft subsequently struck trees and power lines before impacting a small, flat field situated in hilly terrain.
The investigation
Post-crash examination of the wreckage revealed melted aluminum spatter on the underside and leading edge of the left horizontal stabilizer. Investigators also identified focalized fire damage within the cabin area located behind the drain holes in the left wing root.
