## Abstract

The FAA is adopting a new airworthiness directive (AD) for all Boeing Model 727 airplanes. This AD requires doing an initial detailed inspection for cracks in the aft pressure bulkhead web; repairing any discrepancy; and doing repetitive detailed inspections, and doing related investigative actions, if necessary. This AD results from reports of cracking in the aft pressure bulkhead web. We are issuing this AD to detect and correct a cracked pressure bulkhead web, which could result in rapid decompression of the airplane.
