What was found
(CAN) RIGHT MLG WOULD NOT EXTEND. AFTER APPROXIMATELY 150 ATTEMPTS, THE GEAR EXTENDED INTO A DOWN AND LOCKED POSITION. INVESTIGATION REVEALED THAT THE MISALIGNMENT OF THE INBOARD GEAR DOOR DUE TO ELONGATED HOLES IN THE HINGE BRACKETS (P/N 27-55 001-213) CAUSED THE DOOR TO BIND AT THE AFT END PREVENTING THE GEAR FROM EXTENDING.
