What was found
FOUND HINGE ASSY CRACKED LONGITUDINALLY IN SEVERAL PLACES DURING PRE-FLIGHT INSPECTION. UPON FURTHER INVESTIGATION AND DISASSEMBLY, THE DOOR WAS FOUND CRACKED, ALSO, FROM A RIVET HOLE INWARDS TOWARD THE CENTER OF THE DOOR. THIS PART IS CALLED OUT AS PART OF THE TAIL COMPARTMENT ABOVE FLOOR INSPECTION. SUBMITTER SUGGESTS A MORE DETAILED INSPECTION SHOULD BE EMPHASIZED BY GAC. ALSO, A HEAVIER DUTY HINGE ASSY MIGHT BE THE CURE FOR THIS PROBLEM.
