AD 2011-11-01 Airworthiness Directives; British Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 Airplanes

Models named: HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, Jetstream Model 3201. Read the applicability below — it usually turns on serial or part numbers too.

This AD applies to British Aerospace Regional Aircraft Model HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 airplanes, all serial numbers, that are: (1) Equipped with main landing gear (MLG) fittings, part number (P/N) 1379133B1/B2/B3/B4 that incorporate Modifications JM5218 or JM8003; and (2) Certificated in any category.

Unless already done, do the following actions: (1) Upon accumulating 41,000 flight cycles (landings) on the MLG since first installation or within the next 2,000 flight cycles (landings) on the MLG after June 22, 2011 (the effective date of this AD), whichever occurs later, eddy current inspect all the MLG leg pivot beam fastener bores for cracks. Do the inspections following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. (2) Before further flight after any inspection required in paragraphs (f)(1), (f)(2)(i), (f)(2)(ii), and (f)(3) of this AD in which cracks are found, replace the MLG fitting or repair any cracks. Cracks are defined in paragraph 2.D.(4) of British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. Replace or repair the MLG fitting following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. Any time the MLG fitting is repaired or replaced, do the following actions as applicable: (i) MLG fitting is replaced with a new MLG fitting as specified in paragraph (f)(2) of this AD: Upon accumulating 41,000 flight cycles (landings) after replacement, eddy current inspect all the MLG leg pivot beam fastener bores for cracks. Do the inspections following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. (ii) MGL fitting is repaired as specified in paragraph (f)(2) of this AD: Upon accumulating 27,000 flight cycles (landings) after the last repair and repetitively thereafter at intervals not to exceed 27,000 flight cycles (landings), eddy current inspect all the MLG leg pivot beam fastener bores for cracks. Do the inspections following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. (3) If no cracks are found during any inspection required in paragraph (f)(1), (f)(2)(i), or (f)(2)(ii) of this AD, repetitively thereafter upon accumulating 27,000 flight cycles (landings) after the last inspection, eddy current inspect all the MLG leg pivot beam fastener bores for cracks. (4) As of June 22, 2011 (the effective date of this AD), only install a MLG fitting specified in paragraph (c)(1) of this AD that has been eddy current inspected and found free of cracks following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, Revision 1, dated January 18, 2010. (5) Some of the compliance times of this AD are presented in flight cycles (landings). If the total flight cycles have not been kept, multiply the total number of airplane hours time-in-service by 0.75. For the purposes of this AD: (i) 75 cycles equals 100 hours TIS; and (ii) 750 cycles equals 1,000 hours TIS. Note 1: Credit will be given for the inspection required in paragraph (f)(1) of this AD and the corrective action required in paragraph (f)(2) of this AD if already done before June 22, 2011 (the effective date of this AD) following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA090240, original issue dated April 29, 2009; and BEA Systems All Operator Message: Ref 09-014J-1, issue 1, dated July 31, 2009. FAA AD Differences Note 2: This AD differs from the MCAI and/or service information as follows: No differences. Other FAA AD Provisions (g) The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Taylor Martin, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4138; fax: (816) 329-4090; e-mail: taylor.martin@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO. (2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service. (3) Reporting Requirements: For any reporting requirement in this AD, a Federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB Control Number.
