Airworthiness Directive · Amendment 39-11132 · Boeing Model 737-100, -200, -200C, - 300, -400, and -500 Series Airplanes
Boeing Model 737-100, -200, -200C, - 300, -400, and -500 Series Airplanes
Superseded. A later AD replaced this one: AD 2012-18-13. Comply with the one in force.
All Model 737-100, -200, -200C, -300, -400, and - 500 series airplanes; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Boeing Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This action 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; and corrective actions, if necessary. This amendment is prompted by several reports of fatigue cracking found at that location on Model 737 series airplanes. The actions specified in this AD are intended to detect and correct such fatigue cracking, which could result in rapid decompression of the fuselage.
