## Probable cause

THE INSTRUCTOR PILOT NOT MAINTAINING DIRECTIONAL CONTROL FOLLOWING ENGINE SHUT DOWN AND NOT PERFORMING REMEDIAL ACTION OF A POWER REDUCTION TO REGAIN DIRECTIONAL CONTROL, AS PRESCRIBED BY HIS COMPANY'S TRAINING MANUAL, ONCE THE AIRPLANE BEGAN TO YAW/TURN TO THE LEFT.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - directional control - not maintained, pilot in command(cfi) (cause)
  - remedial action - not performed, pilot in command(cfi) (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE TRAINEE STATED SHE WAS FLYING FINAL APPROACH AT 95 KIAS WITH THE POWER SET AT APPROXIMATELY 400 POUNDS OF TORQUE. THE INSTRUCTOR PILOT COMMANDED THE TRAINEE TO GO AROUND.  THE TRAINEE STATED SHE APPLIED FULL POWER. SHORTLY AFTER THE FULL POWER APPLICATION THE INSTRUCTOR PILOT STATED HE OBSERVED A LEFT YAW.  THE INSTRUCTOR PILOT TOOK CONTROL OF THE AIRPLANE AND FEATHERED THE LEFT PROP. THE AIRPLANE CONTINUED ITS LEFT YAW/TURN UNTIL GROUND COLLISION. APPROXIMATELY 120 DEGREES TO THE LEFT OF THE RUNWAY HEADING.  TEAR DOWN OF THE LEFT ENGINE AND ITS CONTROLS REVEALED NOTHING WHICH WOULD HAVE CAUSED A POWERPLANT FAILURE. THE AIRCRAFT OPERATING MANUAL STATES THE FINAL APPROACH SPEED OF THE AIRPLANE SHOULD BE 96 KIAS.  V-MC IN THE AIRPLANE IS 86 KIAS.
