## Discrepancy

(CAN) HAD STARTER FAILURES WHERE THEY SEIZED AND OVERHEATED.  INVESTIGATION REVEALED THAT IF PILOT AGGRESSIVELY ROTATED KEY IN CLOCKWISE DIRECTION THAT KEY WOULD JAM AND LEAVE SWITCH IN THE START POSITION.  THIS WOULD CAUSE THE STARTER TO REMAIN ENGAGED UNTIL IT SMOKED.  REPLACED SWITCH WITH NEW, ALL CORRECT.
