Background: | Cracks were reported in fuselage frame 179 at the attachment bracket for the door restraint cable. The cracks have been attributed to an initial high load on the cable with continued high load use. This directive requires an inspection and cable adjustment check, repeat inspections, and closing action comprising installation of new doublers to reinforce the frame. |
