Airworthiness Directive · Amendment 39-15369 · Wings
Saab Model SAAB SF340A and Model SAAB 340B Airplanes
This AD applies to Saab Model SAAB SF340A and Model SAAB 340B airplanes, certificated in any category, serial numbers 004 through 401.
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:
Within 72 months after the effective date of this AD, unless already done, do the actions described in paragraphs (f)(1) and (f)(2) of this AD.
(1) Do Modification 2762 and all related investigative actions and applicable corrective actions, in accordance with the Accomplishment Instructions of Saab Service Bulletin 340-57-031, Revision 02, dated September 28, 2005. Do all applicable related investigative and corrective actions before further flight. Actions done before the effective date of this AD in accordance with the Accomplishment Instructions of Saab Service Bulletin 340-57-031, dated September 4, 1996; or Revision 01, dated June 28, 1999; are considered acceptable for compliance with the requirements of this paragraph.
(2) For airplanes identified in Saab Service Bulletin 340-57-010, dated March 28, 1989, do the additional corrective actions described in and in accordance with the Accomplishment Instructions of that service bulletin.
Note 1: This AD differs from the MCAI and/or service information as follows: The MCAI does not require doing the actions of Saab Service Bulletin 340-57-010, which is specified in Saab Service Bulletin 340-57-031, Revision 02, as the appropriate source of service information for doing additional corrective actions for certain airplanes to completely address the unsafe condition. This AD requires accomplishing the additional corrective actions described in Service Bulletin 340-57-010 for certain airplanes.
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.
