Probable cause

A partial loss of engine power during cruise flight for reasons that could not be determined because the airplane was not recovered.

NTSB narrative

The flight instructor reported that he was performing an introductory flight lesson for a student with her parents on board as passengers. Rather than fly in the normal practice area, the flight instructor and student decided to fly across a channel toward an adjacent island to avoid unfavorable weather conditions. The student flew the majority of the flight following the shoreline until the flight instructor took the flight controls and turned the airplane inland to return to the airport. As the flight instructor flew the airplane over mountainous terrain, the engine lost partial power, and the airplane then began to descend. The flight instructor subsequently performed a forced landing into densely forested terrain. The airplane was not recovered from the accident site, and it could not be examined on site due to the inhospitable and remote terrain; therefore, the reason for the partial loss of engine power could not be determined.
