Piper Service Bulletin 1372. Main Wing Spar Inspection. 20 pages. Lowers the initial inspection time for many as compared to the AD. Adds recurring inspections. Info on installing over size bolts to fix some holes that are scratched but not cracked. Also a reinforcing kit for some models (no Arrows). No price on the kit yet. Wonder if the FAA will revise the AD.
