Accident Details
The pilot-in-command, holding a commercial pilot certificate, was allowing a passenger to fly the aircraft for a simulated engine-out approach to a full-stop landing. The passenger was a certified flight instructor but did not have a current medical certificate. During the approach, while attempting to stretch the final glide, the passenger allowed the airspeed to become too slow. This caused the aircraft to begin descending at an excessive rate.
Despite the developing situation, the pilot-in-command did not take any remedial action. The aircraft continued its descent and ultimately impacted the terrain approximately 40 feet short of the runway. The impact resulted in substantial damage to the airframe.
Probable Cause
According to the investigation, the probable cause of the accident was the passenger letting the airspeed get too slow while trying to stretch the final glide, and the pilot-in-command not taking remedial action.
