## Probable cause

THE PARTIAL POWER LOSS DUE TO A DISCONNECTED THROTTLE CABLE. A FACTOR WAS THE LACK OF SUITABLE TERRAIN AT THE PILOT'S DISPOSAL.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(partial) - mech failure/malf, approach - vfr pattern - base turn
  - throttle/power lever,cable - disengaged (cause)
  - throttle/power control - not possible, dual student
- Forced landing, descent - emergency
  - emergency procedure - performed, pilot in command(cfi)
- Main gear collapsed, landing - roll
  - terrain condition - crop
  - terrain condition - none suitable (contributing factor)

## Analysis

AN INSTRUCTOR WAS PROVIDING QUALIFICATION TRAINING TO THE NEW OWNER OF THE AIRPLANE. ON HIS FIFTH STOP AND GO LANDING, THE PILOT RETARDED THE THROTTLE TO IDLE ABEAM HIS INTENDED LANDING POINT. WHILE ON BASE LEG, HE ADVANCED THE THROTTLE TO ADJUST HIS RATE OF DESCENT BUT THE ENGINE FAILED TO RESPOND AND CONTINUED TO RUN AT IDLE SPEED. CONTROLS WERE TRANSFERRED TO THE INSTRUCTOR WHO ALSO ATTEMPTED TO INCREASE POWER WITHOUT SUCCESS. EXAMINATION OF THE WRECKAGE REVEALED THAT A RETAINING CLIP ANCHORING THE THROTTLE CABLE ASSEMBLY TO THE FIREWALL WAS MISSING THUS ALLOWING THE ENTIRE HOUSING TO MOVE WHENEVER THE THROTTLE WAS ADVANCED OR RETARDED. WHILE ATTEMPTING A FORCED LANDING TO A CULTIVATED FIELD, THE LEFT MAIN GEAR WAS SEVERED ON IMPACT WITH THE FURROWS.
