What was found
ENTRANCE STAIR EXTENSION: AIR STAIR DOOR OPENS NORMALLY BUT WHEN I STEPPED ON THE STAIRS THE HANDLE JUMPS FROM ITS'S OVER-CENTER POSITION TO AN UNSECURED POSITION AND THE DOOR DROPS TO A POSITION ABOUT 1/2 INCH FROM THE GROUND AND BINDS AGAINST THE FUSELAGE. THE DOOR CANNOT BE CLOSED FROM INSIDE THE AIRCRAFT AFTER THIS HAS OCCURRD. WHEN I TRIED CLOSING THE DOOR FROM THE OUTSIDE, IT WOULD ONLY CLOSE AFTER I MOVE THE HANDLE MANUALLY BACK TO THE OVER-CENTER POSITION. AFTER INSPECTION OF WHERE THE DOOR WAS BINDING AGAINST THE FUSELAGE, AN AREA ABOUT THE SIZE OF A QUARTER ON THE FUSELAGE HAS THE PAINT CHIPPED OR SCRAPED AWAY AND SAME ON THE DOOR. TO MAKE SURE I DIDN'T MAKE A MISTAKE OPENING THE DOOR THE FIRST TIME, I REPEATED THE PROCESS WITH THE SAME RESULTS. // SIGNOFF// ACCOMPLISHED FUNCTIONAL TEST OF PASS DOOR PER BD-100 AMM 52-11-00- 720· 801.
