Sheared or missing fasteners canbe quickly identified as the result of the detailed inspection from outside, forthe loose fasteners however it could be more difficult. In particular, based onthe in-service experience, some fasteners affected by paint peeling can bewrongly considered loose due to the black marks around the fastener head,the so called fastener rash phenomenon. Recommendation to detect loose fasteners:- Paint chipping of fastener head detected from outside is a good indicator, but must not be the only evidence.- Check for abnormal gap under the fastener heads on both sides.- Fastener movement (play) confirm the fastener is loose. However,sometimes the fastener can be loose and stuck (between skin andframe), that is why it is necessary to check on both sides of the cargo door.(1) 详细检查后货仓门挂钩间隙Do a Detailed Inspection of the AFT Cargo Compartment Door Hook Gaps (a) 参考AMM 52-32-00, Page Block 001确保后货舱门正确的关闭和锁上。Make sure the AFT Cargo Compartment Door is correctly closed and locked, refer to AMM 52-32-00, Page Block 001.(b) 将后货舱门锁手柄搬动至非锁上位置。Put the AFT Cargo Compartment Door locking handle in the unlocked position.(c) 参考Fig. A-GBAAA Sheet 01和AMM Task 52-32-11-820-803测量以下位置处挂钩间隙的“U”值和“V”值，并在后附记录表中记录检查结果。Measure and record the hook gaps U and V at the locations detailed below, refer to Fig. A-GBAAA Sheet 01 and AMM Task 52-32-11-820-803.隔框60、隔框60A、隔框61、隔框61A、隔框62、隔框62A、隔框63、隔框63A、隔框64和隔框64A。Frame 60, Frame 60A, Frame 61, Frame 61A, Frame 62, Frame 62A, Frame 63, Frame 63A, Frame 64 and Frame 64A. 挂钩间隙U和V在规定容限内Hook gaps U and V are within specified tolerances 挂钩间隙U和V不在规定容限内Hook gaps U and V are out of tolerances(d) 假如挂钩间隙U和V在规定容限内，执行步骤“详细检查后货舱门隔框叉形接头区域”和“详细检查后货舱门隔框顶部区域”。If hook gaps U and V are within specified tolerances, go to Do a Detailed Inspection of the AFT Cargo Compartment Door Frame Fork Areas and Do a Detailed Inspection of the AFT Cargo Compartment Door Frame Head Areas .(e) 假如挂钩间隙U和V不在规定容限内，执行步骤“详细检查后货舱门隔框叉形接头区域”和“详细检查后货舱门隔框顶部区域”。If hook gaps U and V are out of tolerances, go to Do a Detailed Inspection of the AFT Cargo Compartment Door Frame Fork Areas and Do a Detailed Inspection of the AFT Cargo Compartment Door Frame Head Areas .1 检查和修理完成后，调节挂钩间隙，执行步骤“调节后货舱门挂钩间隙”：Do the hook gap adjustment after the inspection and any resulting repairs are completed go to Do the Adjustment of the AFT Cargo Compartment Door Hook Gaps .
