Superseded. A later AD replaced this one: AD 2009-19-03. Comply with the one in force.
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. 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, inspect the main landing gear (MLG) radius rod to identify if you have one of the affected part numbers (P/Ns) (P/N 1847/D through 1847/N and 1862/D through 1862/N) installed on the airplane following British Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-JA090640, dated June 2009. If you do not have one of the affected P/Ns installed, then only paragraphs (f)(3) and (f)(4) of this AD apply to you.
(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, replace the MLG radius rod with one of the following:
(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 June 26, 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.
Note 1: The inspection requirements of paragraph (f)(3) above apply to any replacement required per AD 2007-21-17.
(4) Within 30 days after the inspection required in paragraph (f)(1) of this AD, send an Accomplishment (Inspection) Report to BAE Systems following the instructions in paragraph 2.C of British Aerospace Jetstream Series 3100 and 3200 Alert Service Bulletin 32-A-JA090640, dated June 2009. Include the details of any radius rods removed.
Note 2: 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.
