THE PILOT-IN-COMMAND SELECTED THE 40 DEGREE FLAP POSITION FOR HIS APPROACH AND LANDING. THE AIRPLANE 'FELL OUT OF THE SKY' ON SHORT FINAL. AFTER EXITING THE AIRPLANE HE NOTICED THE FLAP HANDLE WAS IN THE 30 DEGREE POSITION. EXAMINATION OF THE AIRPLANE AND FLAP SYSTEM SHOWED THAT THE HANDLE WOULD NOT STAY IN THE 40 DEGREE SELECTED POSITION IF BUMPED. THE FLAP HANDLE WAS VERY STIFF WHEN POSITIONED FROM THE 30 DEGREE TO THE 40 DEGREE POSITION AND WOULD NOT COMPLETELY LATCH ON THE 40 DEGREE POSITION.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: THE INADVERTENT RAISING OF THE FLAPS. Full narrative available
