Required Actions
Inspect the 1G unit panel for an asterisk after the part number (P/N). If an asterisk is present, inspect for a rubber extrusion on the stringer. If no rubber extrusion is installed, remove the 1G unit, bond a rubber extrusion on the stringer, reinstall the 1G unit, and functionally test the emergency flotation gear control system. If no asterisk is present, remove the 1G unit and inspect for interference between harness wires and the stringer, as well as between internal parts. Bond a rubber extrusion on the stringer if none is installed. Inspect for interference between the attachment screw and harness wires, and for wire damage. Modify the 1G unit as necessary to prevent interference and mark an asterisk after the P/N. Reinstall and functionally test the 1G unit. Installing a conforming 1G unit is the terminating action.
