1. Based on the measurement from Section 3, Inspection, chose one of the
replacement W-1207B-x rear spar doublers. There are four different ones
available, ranging from 0.025 to 0.055 longer than the original, in increments of
0.010 — (i.e: W-1207-25 is 0.025” longer than stock.) Note that a pattern of holes
punched in the inboard end indicates the size – one extra hole is the first
oversize then two, three and four holes are used to identify each progressively
longer part.
2. Prepare the doubler by sanding the rounded end just enough to remove the
rough surface left from manufacture, no more.
3. Prime the doubler if/as desired.
4. Remove the wing and drill out the rivets attaching the W-1207B rear spar
doubler, W-1212 and hinge assembly to the rear spar. See KAI Section 5.4.
