DEFLECTOR DOOR - APPROVED REPAIRS
1. General
A. The studs and spacers mounted on the deflector doors are retained by a nutplate sandwiched between outer and inner deflector door skins. As the nutplate is inaccessible, a special method of repair is required to replace the nutplate without removing the door skins.
2. Repair Deflector Door
A. Enlarge hole in deflector door skin to .343/.350-inch diameter. Enlarge the two rivet holes to .128 inch. (See detail A, figure 801.)
B. Rework a NAS680C3 nutplate by enlarging rivet holes to .128 inch.
C. Attach a piece of safety wire to nutplate and insert nutplate through hole; align rivet holes and install two CR2562S-4 rivets.
NOTE: When a CFA18-3-14 screw is installed on a lower door that has been repaired using the above method, screw will protrude .037 inch above skin line. This is acceptable on a repair installation.
