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 repetitive, detailed visual inspections of the windshield wiper assembly for discrepant conditions, and corrective actions, if necessary. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent failure of the windshield wiper assembly, which could result in loss of visibility, damage to the propeller(s), or penetration of the fuselage skin and consequent depressurization of the airplane.
