Models named: 747-400, 747-400F, 767-200, 767-300 series, PW4000 series. Read the applicability below — it usually turns on serial or part numbers too.
Applicability*9
Model 747-400, 747-400F, 767-200, and 767-300 series airplanes equipped with Pratt & Whitney Model PW4000 series engines; certificated in any category. Note 1: For airplanes that have current-production fan blades (Phase 3, FB2C) installed on all engines, the performance adjustments in the attachments to Boeing Telex M-7200-00-02672, dated November 1, 2000, as referenced in this AD, are not applicable. However, this AD requires revising the Airplane Flight Manual (AFM) for all airplanes to address the potential for future installation of certain early-production fan blades (Phase 0/1, FB2B or FB2T). Note 2: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (c) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance
Required as indicated, unless accomplished previously. To prevent reduced acceleration and climb performance, relative to performance data in the AFM, which could result in runway overruns or impact with obstacles or terrain, accomplish the following: AFM Revision (a) Within 30 days after the effective date of this AD, revise the FAA-approved AFM by inserting a copy of this AD with Boeing Telex M-7200-00-02672, dated November 1, 2000, including the performance adjustments in “Performance for Operation of PW4000 Series Engines with FB2B or FB2T Fans Installed[,] 747-400,” (for Boeing Model 747-400 and 747-400F series airplanes) or “Performance for Operation of PW4000 Series Engines with FB2B or FB2T Fans Installed[,] 767-200/767-300,” (for Boeing Model 767-200 and -300 series airplanes), both dated November 1, 2000, as applicable. (b) When the information in Boeing Telex M-7200-00-02672 and its attachments have been incorporated into FAA-approved general revisions of the AFM, the general revisions may be incorporated in the AFM, and this AD with the telex and its attachments may be removed from the AFM. Alternative Methods of Compliance (c) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, Seattle Aircraft Certification Office (ACO), FAA. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Seattle ACO. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Seattle ACO. Special Flight Permits (d) Special flight permits may be issued in accordance with sections 21.197 and 21.199 of the Federal Aviation Regulations (14 CFR 21.197 and 21.199) to operate the airplane to a location where the requirements of this AD can be accomplished. Incorporation by Reference (e) The actions shall be done in accordance with Boeing Telex M-7200-00-02672, including Attachments “Performance for Operation of PW4000 Series Engines with FB2B or FB2T Fans Installed[,] 747-400” and “Performance for Operation of PW4000 Series Engines with FB2B or FB2T Fans Installed[,] 767-200/767-300,” dated November 1, 2000, as applicable. (Note: The attachment titles are indicated only on the first page of each attachment; no other page contains this information.) This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51. Copies may be obtained from Boeing Commercial Airplane Group, P.O. Box 3707, Seattle, Washington 98124-2207. Copies may be inspected at the FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of the Federal Register, 800 North Capitol Street, NW., suite 700, Washington, DC. Effective Date (f) This amendment becomes effective on February 6, 2001. Issued in Renton, Washington, on January 9, 2001. Donald L. Riggin, Acting Manager, Transport Airplane Directorate, Aircraft Certification Service. [FR Doc. 01-1234 Filed 1-19-01; 8:45 am] BILLING CODE 4910-13-P
