Private Airstrip Airport
Aircraft Accident/Incident Report

Naples, Idaho 83847
Saturday, September 11, 1999 17:00 PDT

NTSB Narrative Summary Released at Completion of Accident

A witness reported that after the aircraft took off, it made an immediate 180-degree turn back to the departure area. It then appeared to the witness to attempt a landing, descending to within 2 to 4 feet of the surface, but at midfield appeared to the witness to be too fast to land. The aircraft then began a go-around and another turn back to the departure area. During the second turn back to the departure area, the aircraft entered an abrupt descent and crashed. An FAA on-scene investigator found barbed wire entangled with the aircraft wreckage, and leading edge gouges on the aircraft's propeller blades matching the diameter of the barbed wire. The departure area has barbed-wire fences at either end. The FAA investigator found no evidence of pre-impact flight control or engine malfunction.

NTSB Probable Cause Narrative

The pilot's failure to maintain adequate airspeed during a turn back toward the departure surface, resulting in a stall.
