Models named: 737-100, -200, -200C, -300, -400, -500 series. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

(1) This AD applies to The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 30, 2013. (2) Installation of Supplemental Type Certificate (STC) ST01219SE ( http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/ebd1cec7b301293e86257cb30045557a/$FILE/ST01219SE.pdf ) does not affect the ability to accomplish the actions required by this AD. Therefore, for airplanes on which STC ST01219SE is installed, a “change in product” alternative method of compliance (AMOC) approval request is not necessary to comply with the requirements of 14 CFR 39.17.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

For Groups 1 through 4 airplanes identified in Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 30, 2013: Within the applicable compliance times specified in Tables 1 through 10 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 30, 2013, except as provided by paragraph (j)(1) and (j)(3) of this AD, do the applicable detailed and low frequency eddy current inspections for any cracking of the skin and bear straps in the corners of the forward galley service door, and do all applicable corrective actions, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 30, 2013, except as required by paragraph (j)(2) of this AD. Do all applicable corrective actions before further flight. Repeat the inspections at the applicable time specified in Tables 1 through 10 of paragraph 1.E., “Compliance,” of Boeing Alert Service Bulletin 737-53A1116, Revision 4, dated September 30, 2013.

Unsafe condition

This AD was prompted by reports from multiple operators that have found fatigue cracking in the corners of the forward galley service doorway. We are issuing this AD to detect and correct fatigue cracking, which could result in rapid loss of cabin pressure.

Affected ADs

None.
