760-835 Hi-Shear Rivet Replacement

NOTE – I no longer supply these components or in kit form. Someone figured out those little screws and nuts are valuable and I would rather stay out of the high-price competition. I do have a surplus of the screws if you would like to purchase those, $5 each.

Save a bunch; buy this kit.

The photo below shows the content of the Hi-Shear Rivet Kits; however this is not how Piper packages their kits. Their P/N 760-835 “HI-SHEAR RIVET REPLACEMENT” as described in their literature states materials required for one fitting; the kit I provide, pictured above, is for all four fittings including the cover plates; i.e. one kit for the entire airframe, not four kits @ $176.98 each [w/o cover plates] as you would from Piper. This is Piper’s recommended method; not an AMOC. The prevailing wisdom is to do all four at one time, rather than as necessary. If you’re tempted to repair only the loose one[s], would logic not suggest the others will follow?

Another small mention; at the February 2009 Laughlin, Nevada fly-in we discovered one 400 Comanche with loose rivets in the tail cone bulkhead. That condition was discovered during the inspection for loose stabilator bearings and/or loose rivets in the mounting blocks.

Per the photos above; $NLA adequate for one airframe

These photos show how to determine whether the Piper method of compliance has been accomplished. You’re looking for the riveted cover plate as the above photos illustrate.
