AD 2013-02-05 Airworthiness Directives; the Boeing Company
Models named: 737-600, -700, -700C, -800, -900, -900ER series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
This AD applies to The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 737-31A1332, Revision 3, dated March 28, 2012.
Compliance
Comply with this AD within the compliance times specified, unless already done.
Required actions
Within 36 months after the effective date of this AD: Install two warning level indicator lights on each of the P1-3 and P3-1 instrument panels in the flight compartment, and, as applicable, replace the existing P5-16 and P5-10 panels, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737-31A1332, Revision 3, dated March 28, 2012. Note 1 to paragraph (g) of this AD: Note rows (a) and (b) of Figures 1 and 2 of Boeing Alert Service Bulletin 737-31A1332, Revision 3, dated March 28, 2012, provide additional guidance for reworking the P1-3 and P3-1 panels to new part numbers. Section 1.A., “Planning Information—Effectivity,” of the documents specified in those note rows identify part numbers to which those documents apply.
Unsafe condition
This AD was prompted by a design change in the cabin altitude warning system that would address the identified unsafe condition. We are issuing this AD to prevent failure of the flightcrew to recognize and react to a valid cabin altitude warning horn, which could result in incapacitation of the flightcrew due to hypoxia (a lack of oxygen in the body), and consequent loss of control of the airplane.
Affected ADs
This AD affects the ADs identified in paragraphs (b)(1), (b)(2), and (b)(3) of this AD. This AD does not supersede the requirements of these ADs. (1) AD 2003-14-08, Amendment 39-13227 (68 FR 41519, July 14, 2003). (2) AD 2006-13-13, Amendment 39-14666 (71 FR 35781, June 22, 2006; corrected July 3, 2006 (71 FR 37980)). (3) AD 2008-23-07, Amendment 39-15728 (73 FR 66512, November 10, 2008).
