## Summary

We propose to adopt a new airworthiness directive (AD) for certain Model 767-300 series airplanes. This proposed AD would require repetitive inspections for cracks in the fuselage skin and backup structure at the lower very high frequency (VHF) antenna cutout at station 1197 + 99 between stringers 39L and 39R, and corrective actions if necessary. Certain repairs would terminate certain inspection requirements. This proposed AD results from reports of cracking found in the section 46 fuselage lower skin around the periphery of the VHF antenna baseplate at station 1197 + 99. We are proposing this AD to detect and correct fatigue cracks in the fuselage skin and internal backup structure, which could result in rapid decompression of the airplane.
