British Aerospace Regional Aircraft Models Jetstream Series 3101 and Jetstream Model 3201 Airplanes
This AD applies to British Aerospace Regional Aircraft Models Jetstream Series 3101 and Jetstream Model 3201 airplanes, all serial numbers, certificated in any category.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
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.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
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.
