Circumstances:
The airline transport pilot reported that shortly after takeoff from runway 36, he heard a loud noise from the left engine area, and observed smoke trailing the left engine nacelle. He confirmed that the left engine was losing power, and he feathered the left propeller. He was unable to maintain altitude, and the aircraft was force landed on wooded terrain. The aircraft caught fire on the ground after colliding with trees and was destroyed. An inspection of the left engine turbocharger revealed that the rotor shaft was seized, with evidence of metal transfer to the bearing journals.
Probable cause:
The failure of the left engine turbocharger due to rotor shaft seizure, which resulted in a loss of engine power.
