## Probable cause

THE ENGINE STARTED FOR AN UNDETERMINED REASON, WHEN THE PROP WAS MOVED AFTER THE PILOT EXPERIENCED AN INOPERATIVE STARTER.  (MOST PROBABLY, THERE WAS EITHER AN ISOLATED/INTERMITTENT PROBLEM IN THE IGNITION SYSTEM OR THE PILOT DID NOT MOVE THE MAGNETO SWITCH ALL THE WAY TO THE OFF POSITION BEFORE MOVING THE PROPELLER.)

## Sequence of events

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

- Miscellaneous/other, standing - starting engine(s)
  - reason for occurrence undetermined (cause)
  - engine accessories,engine starter - inoperative
- On ground/water collision with object, taxi
  - object - aircraft parked/standing

## Analysis

THE PLT THOUGHT THE PROP WAS STUCK, WHEN THE ENGINE DID NOT START WITH THE BATTERY DRIVEN STARTER.  HE SAID HE TURNED THE MASTER SWITCH OFF, TURNED THE KEY TO THE OFF POSITION AND PULLED THE MIXTURE & THROTTLE LEVERS ALL THE WAY OUT. HE THEN EXITED THE ACFT TO UNSTICK THE PROP BY A SLIGHT MOVEMENT.  HOWEVER, WHEN HE MOVED THE PROP, THE ENG STARTED & THE ACFT MOVED INTO A PARKED AERO COMMANDER.  SUBSEQUENT INSPN OF THE MAGNETO SWITCH & MAGNETOS REVEALED NO IRREGULARITIES.
