## Probable cause

THE INSTRUCTOR PILOTS IMPROPER IN-FLIGHT PLANNING, AND HIS FAILURE TO MAINTAIN A PROPER GLIDE PATH TO THE FORCED LANDING AREA.  A FACTOR IN THIS ACCIDENT WAS THE INSTRUCTOR'S DECISION TO SHUT DOWN THE ENGINE DURING A 'SIMULATED' ENGINE FAILURE .

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, other
  - emergency procedure - simulated, pilot in command
  - in-flight planning/decision - improper, pilot in command (cause)
  - mixture - improper use of, pilot in command (contributing factor)
- Forced landing, descent - emergency
  - proper glidepath - not maintained, pilot in command (cause)
- In flight collision with object, landing
  - object - tree(s)

## Analysis

WHILE PRACTICING SIMULATED ENGINE FAILURES, FROM 4800 FEET ABOVE MEAN SEA LEVEL, THE INSTRUCTOR PILOT PULLED THE MIXTURE LEVER TO THE CUT OFF POSITION CAUSING THE ENGINE TO SHUT DOWN.  THE INSTRUCTOR PILOT AND STUDENT PILOT CONTINUED WITH 'SIMULATED' ENGINE OUT PROCEDURES UNTIL 2500 FEET WHEN AN ATTEMPT WAS MADE TO RESTART THE ENGINE.  AFTER SEVERAL UNSUCCESSFUL ATTEMPTED RESTARTS, THE INSTRUCTOR MANEUVERED THE AIRPLANE TOWARD THE ORIGINAL SIMULATED FORCED LANDING AREA.  HOWEVER, HE OVER SHOT THE FIELD, AND THE AIRPLANE IMPACTED TREES.  THE POST-ACCIDENT EXAMINATION OF THE ENGINE REVEALED IT WAS CAPABLE OF NORMAL OPERATION.
