## Probable cause

A partial loss of engine power due to the turbocharger's seizure as a result of a severely worn turbowheel. Contributing to the accident was the failure of the pilot/owner to have the turbo normalization system inspected every 100 hours as required, which allowed erosion on the exhaust side of the turbowheel to go undetected.
