Airworthiness Directive · Amendment 39-18231 · Wings
British Aerospace Regional Aircraft Airplanes
This AD applies to British Aerospace Regional Aircraft Jetstream Model 3201 airplanes, all serial numbers, that are:
(1) Certificated in any category; and
(2) Modified in service following BAE Systems (Operations) Ltd Service Bulletin (SB) 05- JM8229.
We are adopting a new airworthiness directive (AD) for British Aerospace Regional Aircraft Model Jetstream Model 3201 airplanes. 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 the in-service special detailed inspection technique required for the Jetstream 3200's life extension program was delayed; consequently, the in-service special detailed inspection technique is not formally part of the life extension program and may therefore not be accomplished as intended. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions as specified in paragraphs (f)(1) through (f)(3) of this AD:
(1) Before accumulating a total of 53,950 flight cycles (FC) on the airplane or within the next 50 FC after September 21, 2015 (the effective date of this AD), whichever occurs later, and repetitively thereafter at intervals not to exceed 14,300 FC, accomplish an eddy current (EC) and an x-ray inspection of the wing main spar around rib 36 following the instructions of British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57-JA140140, Original Issue, dated June 26, 2014. For the purposes of this AD, owner/operators who do not track total FC must multiply the total number of airplane hours time-in-service (TIS) by 0.75 to calculate the cycles.
(2) If any crack or corrosion is found during any inspection required by paragraph (f)(1) of this AD, before further flight, contact BAE Systems (Operations) Ltd for FAA-approved repair instructions approved specifically for this AD and accomplish those instructions. You can find contact information for BAE Systems (Operations) Ltd in paragraph (i)(3) of this AD. Use the Operator Report Form and follow the instructions in British Aerospace Jetstream Series 3100 & 3200 Service Bulletin 57-JA140140, Original Issue, dated: June 26, 2014.
(3) Repair of an airplane as required in paragraph (f)(2) of this AD does not terminate the repetitive inspections required in paragraph (f)(1) of this AD for that airplane, unless the approved repair instructions state otherwise.
