Incident Overview
Following takeoff, the pilot communicated to the tower that a return to land was necessary due to loss of power to the right engine. Witnesses on the ground observed that the airplane exhibited a pronounced right yaw and an out-of-trim attitude as soon as it became airborne.
Examination of Wreckage
Inspection of the wreckage revealed that the rudder trim was set to 50% nose right position.
Previous Events
The pilot had made a precautionary landing at the same airport the night before, citing a reported partial loss of power on the left engine. Maintenance personnel subsequently identified and repaired the source of that power loss. During that maintenance, the pilot informed the mechanics that both engines were beyond their recommended time between overhauls (TBO) and expressed concern about engine reliability.
Engine Examination
Teardown and detailed examination of both engines and their turbochargers did not reveal any anomalies that would have prevented normal engine operation.
