## Analysis

THE AIRCRAFT CRASHED 150 YARDS SHORT OF THE RUNWAY DURING LANDING. THE PILOT SAID THE MANIFOLD PRESSURE KEPT FALLING AS HE PROGRESSED AROUND THE FIELD IN THE TRAFFIC PATTERN. THE ENGINE WENT TO IDLE ON THE BASE LEG. THE PILOT HAD LOWERED THE GEAR BUT NOT THE FLAPS. WHEN IT BECAME APPARENT THE RUNWAY WOULD NOT BE REACHED HE PICKED A LANDING SPOT AND LOWERED THE FLAPS. THE ROUGH AREA OF LANDING TORE OFF THE LANDING GEAR AND SLOWED THE AIRCRAFT. INSPECTION SHOWED THAT THE THROTTLE CONTROL SPRING STUD ASSEMBLY NUT WAS MISSING WITH THE STUD DETACHED FROM THE THROTTLE. THE STUD WAS PLACED IN POSITION ON THE THROTTLE ARM AND FELL AWAY AFTER ABOUT 15 CYCLES OF THROTTLE ACTUATION FROM THE COCKPIT. THE ENGINE HAD JUST BEEN OVERHAULED AND INSTALLED, AND AN ANNUAL INSPECTION HAD BEEN PERFORMED ON DECEMBER 11, 1982. TOTAL TIME SINCE WAS ABOUT 10 HOURS.
