## Summary

We propose to revise an existing airworthiness directive (AD) that applies to all The Boeing Company Model 737-100, -200, -200C, - 300, -400, and -500 series airplanes. The existing AD requires repetitive inspections to detect cracking in the web of the aft pressure bulkhead at body station 1016 at the aft fastener row attachment to the ''Y'' chord, various inspections for discrepancies at the aft pressure bulkhead, and related investigative and corrective actions if necessary. Since we issued that AD, we have determined that certain inspection and repair conditions must be clarified, as well as certain paragraph references related to the terminating action. This proposed AD would clarify certain actions specified in the existing AD. We are proposing this AD to detect and correct fatigue cracking, which could result in rapid decompression of the fuselage.
