## Discrepancy

DURING ANNUAL INSPECTION, ON THE PILOT'S DOOR FOUND SEVERE WEAR ON THE HARDWARE FOR THE ARM, CABIN DOOR STOP. THESE ARE COVERED BY INTERIOR TRIM. THE 8/32 MS27039-0816 SCREW AND 2 EA. 1411206-1 SPACERS ATTACHED TO THE ARM WERE WORN ALMOST ALL THE WAY THROUGH BY A SAWING ACTION. THESE PARTS RIDE IN A HARD STEEL BRACKET WITH A TENSION SPRING AND HAD NO OBSERVED LUBRICATION. THE MAIN CONCERN IS FAILURE OF THESE PARTS WOULD ALLOW THE CABIN DOOR TO SWING OPEN AND CONTACT THE WING STRUT WHICH IS A CRITICAL PART WITH VERY LIMITED OR NO DAMAGE ALLOWED. REPLACED ALL WORN PARTS AND LUBRICATED WITH AEROSHELL 22. THE CESSNA MM CH12 AND 52 DO NOT ADDRESS LUBRICATION OF THIS.
