## Probable cause

FAILURE OF THE THROTTLE CABLE ASSEMBLY WHICH RESULTED IN A FORCED LANDING AND SUBSEQUENT COLLISION WITH A FENCE.

## Sequence of events

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

- Airframe/component/system failure/malfunction, approach - vfr pattern - final approach
  - throttle/power lever,cable - failure,total (cause)
- Forced landing, descent - emergency
- On ground/water collision with object, landing
  - object - fence

## Analysis

THE INSTRUCTOR PILOT SAID THAT WHILE ON FINAL APPROACH FOR LANDING, THE ENGINE FAILED TO RESPOND TO THROTTLE INPUTS. UNABLE TO REACH THE AIRPORT, AN EMERGENCY LANDING WAS ATTEMPTED IN A SOY BEAN FIELD WHERE THE AIRCRAFT COLLIDED WITH A FENCE. POST ACCIDENT INVESTIGATION REVEALED THE THROTTLE CABLE ASSEMBLY HAD FAILED.
