Applicability*9

This AD applies to The Boeing Company Model 737-400 series airplanes, certificated in any category, having serial numbers 23865, 24231, 24706, 24474, 25417, 27003, 27149, 25375, 26281, 28661, and 28881, as modified by Supplemental Type Certificate ST01114WI ( http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/f9490633c04cbc8286257301006ed621/$FILE/ST01114WI.pdf ).

Compliance

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

Required actions

Within 6 months after effective date of this AD, do a detailed inspection of Advanced Aircraft Extinguishers cargo fire protection system (FPS) placards to determine if they are the correct placards and in the correct location, and do all applicable corrective actions, in accordance with the “SERVICE BULLETIN INSTRUCTIONS” of Advanced Aircraft Extinguishers Service Bulletin TFA10-26-0020, Revision IR, dated January 12, 2015. Do all applicable corrective actions before further flight.

Unsafe condition

This AD was prompted by the discovery of a design drawing error regarding placards that identified incorrect squibs and pressure switches for certain fire extinguisher bottles. We are issuing this AD to detect and correct incorrectly installed harnesses for the cargo fire suppression system bottles, which could result in an incorrect activation sequence of the bottles, the inability to suppress a cargo fire quickly, and a possible uncontrollable fire.

Affected ADs

None.
