Airworthiness Directive · Amendment 39-13989 · Boeing Model 757 Series Airplanes
Boeing Model 757 Series Airplanes
This AD applies to Boeing Model 757-200, -200CB, and -200PF series airplanes identified in Boeing Alert Service Bulletin 757-33A0048, dated March 28, 2002; and Boeing Model 757-300 series airplanes identified in Boeing Alert Service Bulletin 757-33A0049, dated March 28, 2002; certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 757 series airplanes. This AD requires identification of the part number for the cable assembly for the lower anti-collision light, and related investigative and corrective actions if necessary. This AD is prompted by a report of damage caused by an electrical arc in a connector on the cable assembly for the lower anti-collision light. We are issuing this AD to prevent an electrical arc in the cable assembly for the lower anti-collision light, which could result in a fire in a flammable leakage zone of the airplane.
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 60 months after the effective date of this AD: Do an inspection or a review of airplane maintenance records to identify the P/N of the cable assembly for the lower anti-collision light. If Boeing P/N S283T012-15 or Grimes P/N 60-3414-9 is identified, or if the part number of the cable assembly cannot be positively identified, do the related investigative and corrective actions required by paragraph (g) of this AD.
For airplanes having Boeing P/N S283T012-15 or Grimes P/N 60-3414-9, or airplanes on which the P/N of the cable assembly cannot be positively identified: Within 60 months after the effective date of this AD, replace the cable assembly for the lower anti-collision light with a new, improved cable assembly, or modify the existing cable assembly; and do the related investigative actions; in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 757-33A0048 (for Model 757-200, -200CB, and -200PF series airplanes); or 757-33A0049 (for Model 757-300 series airplanes); both dated March 28, 2002; as applicable.
As of the effective date of this AD, no person may install a cable assembly, Boeing P/N S283T012-15 or Grimes P/N 60-3414-9, in a flammable leakage zone on any airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
