Airworthiness Directive · Amendment 39-15929 · Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 Series Airplanes
Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 Series Airplanes
This AD applies to the Boeing airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Model 737-300, -400, and -500 series airplanes, as identified in Boeing Service Bulletin 737-24-1145, dated March 4, 2004.
(2) Model 737-600, -700, -700C, -800, and -900 series airplanes, as identified in Boeing Service Bulletin 737-24-1147, Revision 1, dated March 1, 2007.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 737-300, -400, -500, -600, -700, -700C, -800, and -900 series airplanes. This AD requires installing a new circuit breaker, relays, and wiring to allow the flightcrew to turn off electrical power to the in-flight entertainment (IFE) systems and other non-essential electrical systems through a switch in the flight compartment, and doing other specified actions. This AD results from an IFE systems review. We are issuing this AD to ensure that the flightcrew is able to turn off electrical power to IFE systems and other non-essential electrical systems through a switch in the flight compartment. The flightcrew's inability to turn off power to IFE systems and other non- essential electrical systems during a non-normal or emergency situation could result in the inability to control smoke or fumes in the airplane flight deck or cabin.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
For Model 737-300, -400, and -500 series airplanes: Within 60 months after the effective date of this AD, install a new circuit breaker, relays, and wiring to allow the flightcrew to turn off electrical power to the IFE systems through the IFE/galley switch and do all other specified actions as applicable, by accomplishing all the applicable actions specified in the Accomplishment Instructions of Boeing Service Bulletin 737-24-1145, dated March 4, 2004.
For Model 737-300 series airplanes identified as Group 6 airplanes in Boeing Service Bulletin 737-24-1145, dated March 4, 2004, and equipped with P5-13 module assembly part number (P/N) 69-37321-81: Prior to or concurrently with accomplishing the actions required by paragraph (f) of this AD, replace the lightplate assembly of the P5-13 module assembly with a new lightplate assembly and reidentify and test the modified P5-13 module assembly, in accordance with the Accomplishment Instructions of Boeing Component Service Bulletin 69-37321-31-03, dated August 21, 2003.
For Model 737-600, -700, -700C, -800, and -900 series airplanes: Within 60 months after the effective date of this AD, install a new circuit breaker, relays, and wiring, as applicable, to allow the flightcrew to turn off electrical power to the IFE systems and other non-essential electrical systems through a utility switch in the flight compartment, by accomplishing all of the applicable actions specified in Parts 1, 2, or 3 of the Work Instructions of Boeing Service Bulletin 737-24-1147, Revision 1, dated March 1, 2007.
(i) For Model 737-600, -700, -700C, -800, and -900 series airplanes identified as Groups 3 through 139 inclusive in Boeing Service Bulletin 737-24-1147, Revision 1, dated March 1, 2007, and equipped with P5-13 module assembly P/N 285A1840-3 or -4: Prior to or concurrently with accomplishing the actions required by paragraph (h) of this AD, modify the P5-13 module assembly, in accordance with the Accomplishment Instructions of Boeing Component Service Bulletin 285A1840-24-02, dated August 28, 2003.
For Model 737-800 series airplanes identified in paragraph 1.A.1. of Boeing Service Bulletin 737-23-1189, dated June 27, 2002: Prior to or concurrently with accomplishing the actions required by paragraph (h) of this AD, install wiring for the No. 4 VDU cluster, an INOP marker, and stow clip at the P6-1 circuit breaker panel; reroute certain wiring for the No. 4 VDU cluster between stations 685 and 767; and do a continuity test of the newly installed and rerouted wiring; in accordance with the Accomplishment Instructions of Boeing Service Bulletin 737-23-1189, dated June 27, 2002.
