THE PILOT WAS UNABLE TO START THE AIRCRAFT WITH THE ELECTRIC STARTER WHEN THE BATTERY HAD INSUFFICIENT POWER TO CRANK THE ENGINE. THE PILOT STATED THAT HE SHUT OFF THE BATTERY AND ALTERNATOR SWITCHES, TURNED OFF THE MAGNETO SWITCH, AND REMOVED THE KEYS. HE STATED THAT HE THEN EXITED THE AIRCRAFT AND BEGAN PULLING THE ENGINE THROUGH TO COAT THE CYLINDER WALLS WITH OIL. SUBSEQUENTLY, THE ENGINE STARTED AND THE AIRCRAFT TRAVELED ACROSS THE RAMP AND STRUCK ANOTHER PLANE. AN INVESTIGATION REVEALED THAT THE KEYS COULD BE REMOVED WITH THE IGNITION SWITCH IN THE RIGHT MAG POSITION. A TEARDOWN OF THE SWITCH REVEALED THAT THE CONTACTS WERE BURNED AND THE LOCK CYLINDER CHAMBER WAS WORN. THERE WAS NO RECORD SHOWING COMPLIANCE WITH AD 76-07-12 FOR AN INSPECTION OF THE BENDIX IGNITION SWITCH, PN 10-357200-1.
