Airworthiness Directive · Amendment 39-19168 · Landing gear
British Aerospace Regional Aircraft Airplanes
This AD applies to British Aerospace Regional Aircraft Models HP.137 Jetstream Mk.1, Jetstream Series 200 and 3101, and Jetstream Model 3201 airplanes, all serial numbers, certificated in any category.
We are superseding Airworthiness Directive (AD) 2007-08-06 for British Aerospace Regional Aircraft Models HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as the need for airworthiness limitations for critical components in the main and nose landing gear assemblies. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions listed in paragraphs (f)(1) through (4) of this AD:
(1) For all affected airplanes: Before further flight after March 5, 2018 (the effective date of this AD), replace each component part in the main and nose landing gear assemblies as applicable to airplane model and configuration before exceeding the applicable life limit, following the Accomplishment Instructions in BAE Systems British Aerospace Jetstream Series 3100 and 3200 Service Bulletin 32-JA981042 Rev 9, dated July 11, 2017.
(2) For the affected Model Jetstream 3201 airplanes: Within the next 50 hours after March 5, 2018 (the effective date of this AD), replace alternative port and starboard axles part numbers (P/N) AIR141958 and P/N AIR141959 that have exceeded the applicable life limits as shown in table 5 of BAE Systems British Aerospace Jetstream Series 3100 and 3200 Service Bulletin 32-JA981042 Rev 9, dated July 11, 2017.
(3) For all affected airplanes: Before further flight after March 5, 2018 (the effective date of this AD), revise the FAA-approved maintenance program (instructions for continued airworthiness) that the operator or the owner uses to ensure the continuing airworthiness of each operated airplane, as applicable to the airplane model, by incorporating the limitations described in BAE Systems British Aerospace Jetstream Series 3100 and 3200 Service Bulletin 32-JA981042 Rev 9, dated July 11, 2017, as applicable to the airplane model and depending on the airplane configuration.
(4) For all affected airplanes: The compliance times in paragraphs (f)(1) and (2) of this AD are presented in flight cycles (landings). If the total flight cycles have not been kept, multiply the total number of airplane hours time-in-service (TIS) by 0.75 to calculate the cycles. For the purposes of this AD:
(i) 100 hours TIS ×.75 = 75 cycles; and
(ii) 1,000 hours TIS ×.75 = 750 cycles.
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.
