## Probable cause

A WORN THROTTLE CONTROL ASSEMBLY THAT HAD FAILED.

## 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, go-around (vfr)
  - throttle/power lever - worn (cause)
  - throttle/power lever - failure,total (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, landing
  - terrain condition - high vegetation

## Analysis

WHILE ON A COMMERCIAL PLT CHECK FLT, THE APPLICANT WAS GIVEN A SIMULATED ENG FAILURE. HE SELECTED A DIRT ROAD FOR A SIMULATED FORCED LANDING. AT AN ALT OF ABOUT 500 FT, AFTER THE EXAMINER WAS ASSURED THE APPLICANT COULD HAVE LANDED, THE APPLICANT WAS TOLD TO GO AROUND. THE APPLICANT APPLIED THROTTLE, BUT THE ENG DID NOT RESPOND. WHILE ATTEMPTING TO CORRECT THE PROBLEM, THE ACFT OVERFLEW MOST OF THE ROAD. UNABLE TO LAND ON THE ROAD, THE PLTS SELECTED A FIELD OF SAPLINGS & THE ACFT WAS DAMAGED DURING AN EMERGENCY LANDING. AN EXAM OF THE ENG REVEALED THE THROTTLE CONTROL ASSEMBLY WAS WORN & HAD FAILED, WHICH ALLOWED THE INNER CABLE TO EXIT ITS HOUSING.
