Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB SF340A and SAAB 340B series airplanes. This proposal would require 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. This action is necessary 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.
