Aircraft Accident/Incident Report

Zenia, California 95495
Wednesday, September 20, 1989 17:30 PDT

NTSB Narrative Summary Released at Completion of Accident

THE VFR FLIGHT, CONDUCTED UNDER 14 CFR 135, WAS ROUTINE UNTIL ARRIVING AT SHANNON AIRPORT. AFTER CIRCLING THE ARPT, THE PILOT EXECUTED TWO GO-AROUNDS, BECAUSE HE HAD NOT SLOWED THE AIRPLANE SUFFICIENTLY. HE STATED THAT HE LANDED ON THE THIRD APPROACH, BUT THE AIRPLANE'S AIRSPEED WAS TOO HIGH. REALIZING THAT HE WAS GOING TO OVERSHOOT THE END OF THE RUNWAY, THE PILOT INTENTIONALLY GROUND LOOPED THE AIRPLANE. THIS CAUSED IT TO EXIT THE RIGHT SIDE OF THE RUNWAY AND COLLIDE WITH A FENCE. A POST-ACDNT EXAM DISCLOSED THAT THE FLAP ACTUATOR JACKSCREW HAD SEIZED IN THE UP POSITION.

NTSB Probable Cause Narrative

FAILURE OF THE PILOT TO REALIZE THAT THE FLAPS DID NOT EXTEND, WHICH RESULTED IN EXCESSIVE AIRSPEED. THE SEIZED FLAP ACTUATOR WAS A RELATED FACTOR.
