Flight Details
The pilot and three passengers were returning to a remote area fishing lodge in a float-equipped airplane. According to reports, the pilot flew over the lodge at approximately 200 feet above ground level to alert occupants of the airplane's arrival.
Witness Observations
A witness observed the airplane in a right turn toward the river area, where the pilot intended to land and taxi to the lodge's boat dock. During the turn, the nose of the airplane suddenly dropped toward the ground. The airplane then descended out of the witness's view, behind several trees.
Passenger Recollections
The pilot did not remember the accident. The front seat passenger also could not recall the crash but reported feeling pushed downward into the airplane's seat during the turn.
Post-Accident Examination
Following recovery of the airplane, an examination of the engine did not reveal any evidence of a preimpact mechanical malfunction. No other anomalies were documented.
Conclusion
The investigation did not identify a probable cause for the accident. The engine examination ruled out a preimpact mechanical failure, but the sequence of events leading to the nose-drop remains undetermined.
