What was found
WHEN PERFORMING A MAINTENANCE CHECK OF THE AIR TURBINE STARTER OIL LEVEL, FOUND THAT THE STARTER HAD ROTATED ON THE MOUNTING PAD AND THE SERVICING PORT WAS INACCESSIBLE. THE STARTER WAS REMOVED FOR INSPECTION AND THE ANTI-ROTATION, ALIGNMENT PIN WAS PUSHED FLUSH INTO THE HOUSING WHICH WOULD ALLOW THE STARTER TO EITHER ROTATE OR BE INSTALLED IN THE INCORRECT POSITION. INSTALLED A REPLACEMENT STARTER.
