## Summary

The FAA is revising an earlier proposed airworthiness directive (AD) for certain Boeing Model 767 airplanes. The original NPRM would have required repetitive inspections for cracking of the wing skin, and related investigative/corrective actions if necessary. The original NPRM resulted from reports of cracks found in the lower wing skin originating at the forward tension bolt holes of the aft pitch load fitting. This action revises the original NPRM by revising certain compliance times. We are proposing this supplemental NPRM to detect and correct cracking in the lower wing skin for the forward tension bolt holes at the aft pitch load fitting, which could result in a fuel leak and reduced structural integrity of the airplane.
