The 767-398 Kit Rib Flange – RH is a structural repair or installation kit component used in Piper aircraft wing assemblies. It is designed for the right-hand (RH) side and typically includes flange elements used to reinforce or restore the structural integrity of a wing rib.

Rib flange kits are commonly used during maintenance, repair, or restoration to replace worn, damaged, or corroded flange sections that connect wing skin to the rib structure.

Its primary functions include:

Providing structural reinforcement to wing rib assemblies
Restoring proper attachment surfaces for wing skin panels
Maintaining structural alignment and load distribution in the wing

Rib flange kits like the 767-398 are important for preserving the strength and airworthiness of aircraft wing structures, especially in aging or frequently operated general aviation aircraft.
