Airworthiness Directive · Amendment 39-11987 · Saab Model SAAB SF340A and SAAB 340B Series Airplanes
Saab Model SAAB SF340A and SAAB 340B Series Airplanes
Model SAAB SF340A series airplanes, serial numbers -004 through -159 inclusive; and Model SAAB 340B series airplanes, serial numbers -160 through -459 inclusive; certificated in any category; on which a refuel/defuel panel having part number 7239160-505 is installed.
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 SF340A and SAAB 340B series airplanes, that requires inspecting the connector on the refuel/defuel panel and the electrical connector on the illuminated placard to detect signs of fluid ingression or corrosion, and corrective actions. The actions specified by this AD are intended to prevent electrical shorts or arcing at the illuminated placard connector at the refuel/defuel panel, which could result in a potential ignition source for fuel vapors during fueling procedures. This action is intended to address the identified unsafe condition.
To prevent electrical shorts or arcing at the illuminated panel connector at the refuel/defuel panel, which could result in a potential ignition source for fuel vapors during fueling procedures, accomplish the following:
(a) Within 6 months after the effective date of this AD, inspect the electrical connector on the refuel/defuel panel and the electrical connector on the illuminated placard to detect signs of fluid ingression or corrosion; and accomplish applicable corrective actions (including a sealing procedure, a cleaning/sealing procedure, and repair of corrosion on the refuel/defuel panel mounting plate); in accordance with Saab Service Bulletin 340-28-022, dated February 25, 2000.
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.
