AD 2010-25-02 Airworthiness Directives; British Aerospace Regional Aircraft Models Jetstream Series 3101 and Jetstream Model 3201 Airplanes

Models named: 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 Models Jetstream Series 3101 and Jetstream Model 3201 airplanes, all serial numbers, certificated in any category.

Unless already done, do the following actions: (1) Within 30 days after January 11, 2011 (the effective date of this AD), establish the number of flight cycles (landings) accumulated since installation of each left and right main landing gear radius rod mounting shaft assemblies following paragraph 2.(A) of BAE Systems British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 05-JA090143, dated April 30, 2009. (2) Replace the left and right main landing gear radius rod mounting shaft assembly with an airworthy assembly following British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 32-JA990142, dated March 26, 1999, within the following: (i) For Model Jetstream Series 3101: Within 38,220 total landings accumulated on each main landing gear radius rod mounting shaft assembly or within 1,000 landings after January 11, 2011 (the effective date of this AD), whichever occurs later; and (ii) For Model Jetstream Model 3201: Within 31,038 total landings accumulated on each main landing gear radius rod mounting shaft assembly or within 1,000 landings after January 11, 2011 (the effective date of this AD), whichever occurs later. (3) After replacing each main landing gear radius rod mounting shaft assembly as required by paragraph (f)(2) of this AD, repetitively thereafter replace each assembly with an airworthy assembly at intervals not to exceed the following life limits: (i) For Model Jetstream Series 3101: Within 38,220 total landings; and (ii) For Model Jetstream Model 3201: Within 31,038 total landings. (4) For operators that do not have landing records, determine the number of landings by multiplying the number of hours time-in-service (TIS) accumulated on each main landing gear radius rod mounting shaft assembly by 0.75. For the purpose of this AD: (i) 1,000 landings equals 1,333 hours TIS; (ii) 31,038 landings equals 41,384 hours TIS; and (iii) 38,220 landings equals 50,960 hours TIS. (5) Compliance with the life limits set in paragraph (f)(3) of this AD may be done by incorporating these limits into the limitations section of the aircraft maintenance manual. You may do this by inserting a copy of this AD into the limitations section of aircraft maintenance manual. FAA AD Differences Note: 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, under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq. ), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
