Aircraft Accident/Incident Report

Addison, Texas 75001
Saturday, April 8, 1995 14:40 CDT

NTSB Narrative Summary Released at Completion of Accident

WHILE ON A 1.5 MILE FINAL APPROACH AT ADDISON AIRPORT (ADS) THE PILOT WAS REQUESTED BY THE TOWER CONTROLLER TO SLOW DOWN FOR TRAFFIC SEQUENCING. POWER WAS REDUCED TO SLOW DOWN. AS THE PILOT ATTEMPTED TO INCREASE THROTTLE TO MAINTAIN ALTITUDE, HE NOTICED IT WAS 'JAMMED.' PRIOR TO REDUCING POWER, THE PILOT SAW THAT THE KNOB ASSEMBLY OF THE THROTTLE CONTROL LEVER HAD 'DROPPED OFF.' DURING A LANDING TO AN OPEN FIELD, THE AIRPLANE STRUCK A BERM. EXAMINATION OF THE THROTTLE QUADRANT REVEALED THAT THE THROTTLE CONTROL HAD BECOME MISALIGNED. WHEN THE THROTTLE CONTROL WAS ALIGNED, THE THROTTLE WOULD MOVE FULL TRAVEL FORE AND AFT.

NTSB Probable Cause Narrative

THE JAMMED THROTTLE. FACTORS WERE THE KNOB BECOMING LOOSE AND SEPARATING FROM THE THROTTLE LEVER, AND THE LACK OF SUITABLE TERRAIN AVAILABLE FOR THE FORCED LANDING.
