Airworthiness Directive · Amendment 39-15774 · Landing gear
Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B Airplanes
This AD applies to Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B 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) originated 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.
(1) Within 6 months after the effective date of this AD, do a functional check of the landing gear emergency extension valve in accordance with the Accomplishment Instructions of SAAB Service Bulletin 340-32-136, dated January 9, 2008. Repeat the functional check thereafter at intervals not to exceed 24 months.
(2) If any discrepancy is found during any functional check required by paragraph (f)(1) of this AD, before further flight, repair using a method approved by either the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; or the EASA (or its delegated agent).
Note 1: This AD differs from the MCAI and/or service information as follows: Although the MCAI includes a note that allows the option of the repetitive inspections (functional checks) to be accomplished in accordance with SAAB 340 Maintenance Review Board Report, Section F, Revision 6, Task Number 323106, this AD does not include that option. That document is not yet available.
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.
