THE APPROACH END OF THE RUNWAY TERMINATES IN A STEEP BLUFF WITH A 175-FOOT DROP OFF AT A 70-DEGREE ANGLE. THE AIRCRAFT WAS OBSERVED TO BE LOW ON THE BASE-TO-FINAL TURN. THE PILOT STATED THAT HE WAS 700 FEET HIGHER IN THE PATTERN TO COMPENSATE FOR THE TURBULENCE HE EXPECTED. HE EXTENDED THE SPOILERS AND THEN RETRACTED THEM, AND THEN LOWERED THE NOSE IN AN EFFORT TO INCREASE AIRSPEED. ON FINAL, THE AIRCRAFT DESCENDED BELOW THE TERRAIN AT THE APPROACH END OF THE RUNWAY AND CRASHED INTO THE BLUFF. THE PILOT SAID THAT WHILE IN THE TURN THE AIRSPEED DID NOT INCREASE AS EXPECTED AND HE WAS UNABLE TO REACH THE RUNWAY WHEN THE AIRCRAFT ENCOUNTERED A DOWNDRAFT. THE PREVAILING WINDS WERE CAUSING TURBULENCE AND DOWNDRAFTS AT THE END OF THE RUNWAY WAS CONFIRMED BY THE FAA. THE PILOT HAD BEEN BRIEFED ON THE WIND CONDITIONS AND SAID HE HAD EXPERIENCED THEM PREVIOUSLY.
Probable Cause: the pilot misjudged his planned approach by selecting a touchdown point close to the runway's approach end that did not provide sufficient clearance to safely maneuver when forcast turbulence and downdrafts were encountered. The pilot's early extension of spoilers was a factor in this accident.
