Airworthiness Directive · Amendment 39-12002 · Saab Model SAAB 340B Series Airplanes
Saab Model SAAB 340B Series Airplanes
Model SAAB 340B series airplanes, certificated in any category; serial numbers -380 through -404 inclusive, -406 through -408 inclusive, and -410 through -413 inclusive.
Note 1: This AD applies to each airplane identified in the preceding applicability provision, regardless of whether it has been modified, altered, or repaired in the area subject to the requirements of this AD. For airplanes that have been modified, altered, or repaired so that the performance of the requirements of this AD is affected, the owner/operator must request approval for an alternative method of compliance in accordance with paragraph (b) of this AD. The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 340B series airplanes, that requires a one-time inspection to detect discrepancies of the flight idle stop override mechanism, and corrective action, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent increased braking distance for landings that require the flight idle stop override, resulting from the combination of failure of the override mechanism and inability of the power levers to be moved below the flight idle position after touchdown.
To prevent increased braking distance for landings that require the flight idle stop override, resulting from the combination of failure of the override mechanism and inability of the power levers to be moved below the flight idle position after touchdown, accomplish the following:
(a) Within 30 days after the effective date of this AD, perform a one-time inspection of the flight idle stop override mechanism to detect any discrepancy, in accordance with Saab Service Bulletin 340-76-041, dated May 29, 1997, or Revision 01, dated July 2, 1997. If any discrepancy is found, prior to further flight, replace the control quadrant with a new or serviceable control quadrant in accordance with the service bulletin.
Note 2: Accomplishment, prior to the effective date of this AD, of an operational check, as specified in SAAB 340 Maintenance Review Board (MRB) task 761501, is an acceptable method of compliance with the one-time inspection requirements of paragraph (a) of this AD.
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.
