This AD applies to Model HP.137 Jetstream Mk.1, Jetstream Series 200 and 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 that will supersede an existing AD. This AD results from mandatory continuing airworthiness information (MCAI) issued by the 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) Before further flight after October 5, 2009 (the effective date of this AD) inspect the main landing gear (MLG) radius rods to identify if you have part number (P/N) 1847/D through 1847/N and 1862/D through 1862/N with one of the affected serial numbers listed in British Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009. Perform the inspection following British Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009. Only paragraphs (f)(3) and (f)(4) of this AD apply to you if one or both of the following exists:
(i) If you do not have one of the affected P/Ns installed; and/or
(ii) If you can positively show (maintenance records) that, during the inspection required by AD 2009-13-10, none of the serial number radius rods listed in British Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-JA090640, Revision 2, dated August 11, 2009, are installed.
(2) If as a result of the inspection required in paragraph (f)(1) of this AD you find one of the affected P/N MLG radius rods installed on the airplane, before further flight, install one of the following MLG radius rods:
(i) A serviceable MLG radius rod that is not in one of the following P/N ranges: 1847/D through 1847/N or 1862/D through 1862/N; or
(ii) An affected P/N MLG radius rod that has already been inspected following APPH Ltd. Service Bulletin 1847-32-14 or 1862-32-14, as applicable, both dated June 2009, and found to be serviceable.
(3) As of October 5, 2009 (the effective date of this AD), do not install an affected part number MLG radius rod unless it has been inspected following APPH Ltd. Service Bulletin 1847-32-14 or 1862-32-14, as applicable, both dated June 2009, and found to be serviceable.
