Models named: ATP. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

BAe Model ATP airplanes, having constructor's numbers 2002 through 2063 inclusive; on which Jetstream Modification 10303A (Jetstream Service Bulletin ATP 32-41) has been installed; certificated in any category. Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been otherwise 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 (b) 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 uncommanded application of the brakes during landing, accomplish the following: (a) Within 60 days of the effective date of this AD, accomplish paragraphs (a)(1) and (a)(2) of this AD in accordance with Jetstream Service Bulletin ATP-29-12, dated September 9, 1995. (1) Modify the hydraulic system; and (2) Revise the Emergency and Abnormal Procedures Sections of the FAA-approved Airplane Flight Manual (AFM) to include the information specified in Temporary Revision No. T/52, Issue 1, dated August 16, 1995, which introduces revised procedures for lowering the landing gear, as specified in the temporary revision; and operate the airplane in accordance with those limitations and procedures. Note 2: Paragraph 1.K. of Jetstream Service Bulletin ATP-29-12, dated September 9, 1995, references Temporary Revision No. T/52 as an additional source of service information for revising the AFM. Note 3: This may be accomplished by inserting a copy of Temporary Revision No. T/52 in the AFM. When this temporary revision has been incorporated into general revisions of the AFM, the general revisions may be inserted in the AFM, provided the information contained in the general revisions is identical to that specified in Temporary Revision No. T/52. (b) 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, Standardization Branch, ANM-113, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, Standardization Branch, ANM-113. Note 4: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the Standardization Branch, ANM-113. (c) 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. (d) The actions shall be done in accordance with Jetstream Service Bulletin ATP-29-12, dated September 9, 1995; and Temporary Revision No. T/52, Issue 1, dated August 16, 1995. 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 Jetstream Aircraft, Inc., P.O. Box 16029, Dulles International Airport, Washington, DC 20041-6029.
