## Abstract

We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 727C, 727-100, 727-100C, 727-200, and 727-200F series airplanes. This AD was prompted by the results of a fleet survey, which revealed cracking in bulkhead frame webs at a certain body station. This AD requires repetitive inspections of the bulkhead frame web at a certain body station and applicable on-condition actions. We are issuing this AD to address the unsafe condition on these products.
