## Probable cause

An observed loss of engine power due to the bound/jammed turbocharger wastegate during takeoff, the pilot not maintaining airplane control, and the stall he inadvertently encountered.  A factor was the maintenance personnel not replacing the turbocharger wastegate bypass valve assembly during the last annual inspection 8.7 hours of operation prior to the accident.  An additional factor was the manufacturer's insufficiently defined inspection conditions for the bypass valve's proper operation.
