## Sequence of events

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

- Loss of engine power, approach - vfr pattern - final approach
  - miscellaneous - undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with object, landing - flare/touchdown
  - object - fence (contributing factor)
- Nose over, landing - flare/touchdown

## Analysis

WHILE ON FINAL APPROACH FOR A SIMULATED SHORT FIELD LANDING, THE ENGINE LOST POWER. THE PILOTS WERE UNABLE TO RESTART THE ENGINE, AND THE AIRCRAFT STRUCK A FENCE AND NOSED OVER DURING THE LANDING. CONDITIONS WERE FAVORABLE FOR CARBURETOR ICE, BUT THE INSTRUCTOR REPORTED THAT THE CARBURETOR HEAT WAS ON. AN EXAMINATION OF THE AIRCRAFT REVEALED NO PREIMPACT FAILURE OR MALFUNCTION. THE ENGINE STARTED AND RAN DURING AN OPERATIONAL CHECK.
