## Discrepancy

DURING ANNUAL INSPECTION FOUND SUPPORT ANGLE WHERE LT IB MAIN GEAR DOOR AFT HINGE IS ATTACHED, CRACKED.  PROBLEM NOTED ON OTHER LOW-TIME LATE SERIAL NUMBER BE 58 SERIES AIRCRAFT.  PROBLEM SEEMS TO BE RELATED TO CHANGE TO ONE-PIECE MACHINED IB DOORS DUE TO STIFFNESS OF NEWER STYLE DOORS COMPARED TO THE OLDER BUILT-UP RIVETED SHEET METAL CONSTRUCTION DOORS.  STRESS FROM DOOR AIR LOADS AND/OR RETRACTED POSITION TENSION SEEMS TO BE BEING TRANSFERRED INTO IB DOOR HINGE SUPPORT STRUCTURE. (K)
