Applicability: Model 737-600, -700, -700C, -800 and -900 series aeroplanes which have complied with Requirement 1 of AD/B737/290 using either Boeing Service Bulletin (SB) 737-24A1141 Revision 1 dated 23 December 2004 or Revision 2 dated 1 December 2005.

Later revisions of SB 737-24A24A1141, Revision 3, approved by the United States Federal Aviation Administration (FAA) as an Alternate Method of Compliance (AMOC) to FAA AD 2009-16-07, are considered acceptable for compliance with the equivalent Requirements of this Directive. Note: FAA AD 2009-16-07 Amdt 39-15990 refers. Compliance: Within 12 months after the effective date of this Directive. This Airworthiness Directive becomes effective on 22 October 2009. Background: This Directive supplements AD/B737/357 by requiring, under certain conditions, an additional operational test of the P5-14 panel. The testing of the P5-14 panel ensures correct operation of critical flight systems and the passenger oxygen system. If an improperly functioning passenger oxygen system goes undetected, the passenger oxygen mask could fail to deploy and result in possible incapacitation of passengers during a depressurization event.
