## Probable cause

A FAILURE OF THE LEFT MAGNETO GROUNDING LEAD RESULTING IN A 'HOT MAGNETO' CONDITION.

## Sequence of events

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

- Miscellaneous/other, standing - starting engine(s)
  - ignition system,magneto grounding lead (p-lead) - failure,partial (cause)
- On ground/water collision with object, taxi

## Analysis

DURING ENGINE START, THE PILOT OBSERVED THE STARTER OPERATING, BUT NOT ENGAGING THE ENGINE. HE TURNED OFF THE MAGNETOS AND BATTERY AND EXITED THE AIRPLANE TO INVESTIGATE THE PROBLEM. HE DID NOT CHOCK OR SECURE THE AIRPLANE. HE TURNED THE PROPELLER SOME, THEN BEGAN TO WALK AWAY. THE ENGINE THEN 'ROARED TO LIFE.' THE AIRPLANE PROCEEDED ACROSS THE RAMP AND COLLIDED WITH A PARKED BEECH 77. AN INSPECTION OF THE AIRPLANE REVEALED THAT THE LEFT MAG WOULD NOT GROUND OUT WITH THE SWITCH, RESULTING IN A 'HOT MAG' CONDITION.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
