Overview
According to the pilot's report, shortly after takeoff from runway 36, a loud noise was heard from the left engine area. Smoke was observed trailing the left engine nacelle. The pilot confirmed that the left engine was losing power and subsequently feathered the left propeller. Unable to maintain altitude, the pilot performed a forced landing on wooded terrain. The aircraft caught fire after colliding with trees and was destroyed.
Inspection Findings
An inspection of the left engine turbocharger revealed that the rotor shaft was seized. Evidence of metal transfer to the bearing journals was noted, consistent with a seizure event.
Probable Cause
The official probable cause is the failure of the left engine turbocharger due to rotor shaft seizure, which resulted in a loss of engine power.
