## Probable cause

FAILURE OF THE INSTRUCTOR PILOT TO UTILIZE CARBURETOR HEAT IN ICING CONDITIONS.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, maneuvering
  - weather condition - carburetor icing conditions (contributing factor)
  - carburetor heat - not used, pilot in command (cause)
- Forced landing, descent - emergency
- On ground/water collision with object, landing - roll
  - object - fence

## Analysis

THE CFI PULLED THE THROTTLE TO IDLE SIMULATING AN ENGINE FAILURE. THE STUDENT APPLIED THE EMERGENCY PROCEDURES & AFTER APPLYING THE THROTTLE TO ABORT THE MANEUVER, THE END DID NOT RESPOND. ATTEMPTS TO RESTORE POWER WERE UNSUCCESSFUL. DURING THE FORCED LANDING, THE AFT COLLIDED WITH A FENCE & NOSED OVER. ACCORDING TO THE CHIEF PLT OF THE FLT SCHOOL, THE ENG STARTED & OPERATED NORMALLY AT THE ACCIDENT SITE. CONDITIONS WERE FAVORABLE FOR SERIOUS INDUCTION ICING AT GLIDE POWER.
