Required Actions
Inspect and adjust the cargo door latching mechanism to ensure minimum 0.34 inches clearance between the click-clack plunger face and jaws. Perform three measurements to verify proper engagement of the jaws into the door frame receptacle. Inspect door face plates, receptacles, and switches for deformation, cracks, or sticking, replacing parts as needed. Measure receptacle diameters and replace if oversized. Test the cargo door warning system and perform three door operation cycles. Repeat inspections and adjustments every 1,200 flight hours (if modified) or 250 flight hours (if unmodified).
