Airworthiness Directive · Amendment 39-14375 · Boeing Model 737 Airplanes
Boeing Model 737 Airplanes
This AD applies to the Boeing airplanes listed in Table 1 of this AD, certificated in any category:
| Airplane | Line numbers |
|---|---|
| Model 737-100, -200, -200C, -300, -400, and -500 series airplanes | 1 through 3132 inclusive. |
| Model 737-600, -700, -700C, -800, and -900 series airplanes | 0001 through 1240 inclusive. |
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 737 airplanes. This AD requires, for certain airplanes, a one-time detailed inspection for interference between a clamp assembly and the wires behind the P15 refuel panel, and corrective actions if necessary. For certain other airplanes, this AD requires a one-time detailed inspection for discrepancies of the wires behind the P15 refuel panel; and corrective and related investigative actions if necessary. This AD is prompted by evidence of chafed wiring behind the P15 refuel panel and arcing to the back of the P15 refuel panel and adjacent wing structure. We are issuing this AD to detect and correct chafing of the wiring behind the P15 refuel panel, which could lead to arcing and fire with consequent airplane damage and injury to refueling personnel.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 18 months after the effective date of this AD, perform the following actions as applicable:
(1) For Model 737-100, -200, -200C, -300, -400, and -500 series airplanes: Perform a one-time detailed inspection of the wires in wire bundle W0024 to connector D04578P on the back of the P15 refuel panel for discrepancies, and do any applicable corrective and related investigative actions before further flight, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1193, Revision 1, dated July 28, 2005.
(2) For Model 737-600, -700, -700C, -800, and -900 series airplanes: Perform all applicable actions listed in paragraphs (f)(2)(i) and (f)(2)(ii) of this AD in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1200, Revision 1, dated July 28, 2005.
(i) For Group 1 and Group 2 airplanes as defined in Service Bulletin 737-28-1200: Perform a one-time detailed inspection for discrepancies of the clamp and T-bolt assembly on the wing thermal anti-ice duct near the P15 refuel panel and do any applicable corrective actions before further flight.
(ii) For Group 2 airplanes only as defined in Service Bulletin 737-28-1200: Perform a one-time detailed inspection for discrepancies of the wires in wire bundle W0024 to connector D04578P on the back of the P15 refuel panel and do any applicable corrective actions before further flight.
Note 1: For the purposes of this AD, a detailed inspection is: “An intensive visual examination of a specific structural area, system, installation, or assembly to detect damage, failure, or irregularity. Available lighting is normally supplemented with a direct source of good lighting at intensity deemed appropriate by the inspector. Inspection aids such as mirror, magnifying lenses, etc., may be used. Surface cleaning and elaborate access procedures may be required.”
Actions accomplished before the effective date of this AD in accordance with Boeing Special Attention Service Bulletin 737-28-1193, dated April 24, 2003; or Boeing Special Attention Service Bulletin 737-28-1200, dated July 10, 2003; as applicable; including Information Notices 737-28-1193 IN 01 and 737-28-1200 IN 01; both dated September 11, 2003; as applicable, are acceptable for compliance with the corresponding actions required by this AD.
