## Discrepancy

DURING PRE-BUY INSPECTION, FOUND IGNITION KEY COULD BE REMOVED FROM SWITCH IN ANY POSITION.  DURING LOG BOOK REVIEW, FOUND SWITCH HAD BEEN MODIFIED PER AD 93-05-06 BY INSTALLING ACS/GERDES KIT A-3600.  THIS MODIFICATION WAS DONE AT LAST ANNUAL (8/95) 58 HOURS PREVIOUSLY.  THIS CREATED A HAZARDOUS SITUATION AS KEY COULD BE REMOVED WITH MAGS STILL HOT.  SUSPECT CAUSE WAS HIGH TOTAL TIME.  LACK OF PROPER MAINTENANCE/INSPECTION COULD HAVE CAUSED SERIOUS INJURY.
