Boeing Model 757-200, -200CB, and -300 Series Airplanes
This AD applies to Boeing Model 757-200, -200CB, and -300 series airplanes; certificated in any category; as identified in Boeing Service Bulletin 757-21-0109, Revision 1, dated October 30, 2008.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 757-200, -200CB, and -300 series airplanes. This AD requires a detailed inspection for damage of the wire bundle of the right recirculation fan, and repair if necessary. This AD also requires re-routing the wire bundle of the right recirculation fan. This AD results from a report indicating that, during landing of a Model 757 airplane, an overheat warning and smoke occurred in the main cabin, and the right recirculation fan stopped operating. We are issuing this AD to prevent damage of the wiring bundle of the right recirculation fan. Such damage could result in a short circuit and possible fire in the mix bay or smoke in the main 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.
Within 24 months after the effective date of this AD, do the actions required by paragraphs (f)(1) and (f)(2) of this AD, in accordance with the Accomplishment Instructions of Boeing Service Bulletin 757-21-0109, Revision 1, dated October 30, 2008.
(1) Do a detailed inspection for damage of the wire bundle of the right recirculation fan, and repair any damage before further flight.
(2) Re-route the wire bundle and re-orient the electrical connector of the right recirculation fan.
Actions done before the effective date of this AD in accordance with Boeing Service Bulletin 757-21-0109, dated December 15, 2006, are acceptable for compliance with the requirements of paragraphs (f)(1) and (f)(2) of this AD.
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.
