Incident Overview
An aircraft that had been inactive for two years was involved in an accident shortly after takeoff. Pre-flight inspection revealed evidence of fuel leaking from drain holes in the left wing root, just aft of the main cabin door. A mechanic brought this to the attention of a pilot-rated passenger. Despite the report, the aircraft departed with the pilot (PIC), the aircraft owner, and another passenger/mechanic on board.
Flight and Accident Sequence
Approximately 14 minutes after takeoff, radar data indicated the aircraft transitioning from a climb to a descent while executing a 180-degree turn. Witnesses observed smoke and flames trailing from the aircraft. Subsequently, the aircraft struck trees and power lines before crashing in a small flat field within hilly terrain.
Post-Crash Examination
Examination of the wreckage revealed melted aluminum spatters on the leading edge and underside of the left horizontal stabilizer. Additionally, focalized fire damage was noted on the cabin behind the drain holes in the left wing root.
Toxicology Findings
Toxicological analysis detected tetrahydrocannabinol carboxylic acid (marijuana) in the blood (0.004 μg/mL) and urine (0.010 μg/mL) of the pilot-rated passenger.
