Brief Description: Final-Drill Outboard Right Aileron Hinge Bracket
21-3: Step 1: Cleckoed the righ wing outer hinge bracket to doubler, spar, and main rib and final drilled the #40 holes to be countersunk later. Cleckoed the outer hinge bracket in place and double check I had it assembled correctly by comparing to hinges on right wing. Step 2: Match-drilled #30 middle and outer holes of the hinge assembly and removed one outer clecko. I used a series of drill sizes and gradulally enlarged the hinge bracket outer holes to 3/16 int using a slower portable drill. Disassembled pieces and deburred then reassembled and drilled the second hole after inserting an AN3 bolt,washer, and nut to hold assembly. Step 3: Disassembled and deburred all holes, reassembled doubler to spar and countersunk for NAS1097 rivets to two holes specified.
