Brief Description: QB Inspection of Section 16 Top Wing Skins
1354 - 1430
Verify every step in section 16.
Noted discrepancies on step 2 and 3.
Holes for plate nuts are not final drilled with #40 drill.
Holes for screws in plate nuts are not final drilled to #19.
Rivet along inboard edge of top wing skins installed using incorrect holes near the W-1028 wing box J stiffeners. Rivets were placed assuming use of all K-1000 platenuts, neglecting the MS21051-L08 platenut that gets installed adjacent to the W-1028 J stiffener. When this was noted, information was double checked against the F-1099A cover to confirm proper hole placement for attachment screws. Proper screw holes are indicated in green in the pictures.
Incorrect rivet in W-1002 skin drilled out, 2x.
Final drill all applicable plate nut screw holes using #19 drill.
