Due to a month-long break and doing some steps out of order, we forgot to pull some rivets on the wingtip until just after we’d installed the outboard trailing edge cuff over them. We tried reaching under the cuff to do them, but none of our tools reached. Rather than drill out all the rivets we’d just installed on the trailing edge cuff, we slipped the wingtip out, did some careful measuring to mark the positions of the rivet holes on the cuff, then drilled clearance holes in the cuff so the rivets could be reached through it. The access holes shouldn’t be too obvious under the fabric covering, and affords the possibility of removing the wingtip without removing the trailing edge cuff, should that ever be an unfortunate necessity.

Jet Super Glue is better than the hardware store stuff.
Strapping the leading edge onto the wing so that we can start marking where to drill the holes for the rivets.
Here are some of the manual pages we worked on.
