Accident Narrative

A local sightseeing flight in mountainous terrain involved a passenger request for a left turn. The pilot executed the turn, and after returning the wings to level flight, experienced slight disorientation. The airspeed was dropping, and the vertical speed indicator indicated a 200-foot-per-minute climb. The aircraft had entered a canyon.

Pilot Actions

The pilot assessed the situation and determined that a turn was not possible. Recognizing that the airplane could not outclimb the rising terrain because the airspeed was near stalling speed, the pilot prepared for a collision with the trees. The pilot reported that no mechanical failures or malfunctions occurred with the airplane at the time of the accident.
