Brief Description: Measured Wing Sweep and Incidence
Performed leveling, sweep, and incidence measures per the Service Bulletin instructions and 8-15. Found that the wingtip to fuselage at F706 bulkhead distance was 124 & 5/8" for both wings. Using the plumb bobs, both inboard bobs measured ~1/8" aft of the chalkline snapped between the tip bobs. Using multiple levels and the incidence guide blocks, both wings were found to have no noticeable twist and the bubble levels were centered for both wings, demonstrating the same incidence. Temporarily attached the flaps and checked that the bottom flap skins did in fact just "kiss" the bottom fuselage skin when the flaps were placed in trail. Located holes for rear spar attach bolthole. Verified a minimum of 1/16" over the minimum 5/8" edge distance in all directions.
