THE PRIVATE PILOT (PIC) WAS ON A CHECK-OUT FLIGHT OVER MOUNTAINOUS TERRAIN THAT WAS REQUIRED BY THE FLYING CLUB. THE CHECK PILOT WAS ALSO AN INSTRUCTOR PILOT (CFI). SHORTLY AFTER TAKEOFF, THE PRIVATE PILOT TOLD THE CFI THAT THE AIRPLANE WAS NOT CLIMBING. THE CFI TOOK CONTROL OF THE AIRPLANE, AND NOTED THAT EVEN THOUGH THE AIRSPEED AND PITCH WERE NORMAL, THE AIRPLANE CONTINUED TO DESCEND. WHEN COLLISION WITH TREES WAS INEVITABLE, THE CFI SLOWED THE AIRPLANE TO REDUCE IMPACT FORCES. THE AIRSTRIP WAS SURROUNDED BY TREES AND MOUNTAINOUS TERRAIN, AND THE AREA WAS SUBJECT TO UP AND DOWNDRAFTS. NO EVIDENCE WAS FOUND TO INDICATE A MECHANICAL FAILURE OR MALFUNCTION.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: IMPROPER PLANNING/DECISION BY THE PILOT-IN-COMMAND, AND INADEQUATE SUPERVISION BY THE CHECK PILOT, WHICH RESULTED IN THEIR FAILURE TO REMAIN CLEAR OF TREES DURING TAKEOFF. FACTORS RELATED TO THE ACCIDENT WERE: A DOWNDRAFT AND THE PROXIMITY OF TREES TO THE AIRPORT. Full narrative available
