Airworthiness Directive · Amendment 39-15130 · Wings
British Aerospace Regional Aircraft Jetstream HP.137 Jetstream Mk.1, Jetstream Series 200, Jetstream Series 3101, and Jetstream Model 3201 Airplanes
This AD applies to Jetstream HP.137 Jetstream Mk.1, Jetstream Series 200, 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 using British Aerospace Jetstream Series 3100 and 3200 Service Bulletin 57-JA020740, Revision 2, dated November 2, 2005.
(1) Inspect and torque check the bolts at frame 199 at the following compliance times:
(i) Initially within the next 90 days after August 22, 2007 (the effective date of this AD) or within the next 100 hours time-in-service (TIS) after August 22, 2007 (the effective date of this AD), whichever occurs first; and
(ii) Repetitively thereafter at intervals not to exceed 4,000 hours TIS.
(2) If any discrepancies are found in any of the inspections required in paragraph (f)(1) of this AD, before further flight, correct any discrepancies.
Note: This AD differs from the MCAI and/or service information as follows: We added repetitive inspection requirements in this AD to coincide with the service bulletin.
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.
