Narrative

Shortly after takeoff, the pilot observed that the cylinder head temperature and manifold pressure were both above their red line limits, and engine power began to diminish. The mixture had been set to a lean setting for takeoff. When the pilot closed the turbocharger wastegate, the engine ceased operating. A forced landing was executed on an upslope in terrain described as "slightly hilly." During the landing roll, the aircraft collided with a manzanita bush.

Post-Accident Inspection

Following the accident, an inspection of the engine was conducted. No mechanical failure or malfunction was found during the examination.
