What happened
Shortly after the aircraft departed and the landing gear was retracted, the pilot observed a reduction in power from the left engine. This loss of thrust caused the aircraft to drift toward the left side of the flight path. The plane subsequently struck rising terrain while in a left-wing-low attitude. The impact triggered a fire that heavily damaged the left side of the airframe.
Findings
Post-accident inspections of the left engine showed that while the engine suffered thermal damage, it did not sustain any damage from the impact itself. Specifically, the right-hand turbocharger showed no signs of impact or thermal distress, and the housing and impeller remained free of obstructions or structural damage. However, investigators discovered that the impeller was seized within the center section and was unable to rotate. Evidence of grooving and scraping was present, suggesting that a lack of lubrication to the bearings and drive shaft had occurred. Prior to the takeoff, the pilot had reported no mechanical issues that would have interfered with standard flight operations.
