Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB 2000 series airplanes. This proposal would require repetitive inspections of the installation of the spoilers of the windshield wiper assemblies for discrepancies, and replacement with new spoilers if necessary. The proposal also would require eventual replacement of the spoilers of the windshield wiper assemblies with new spoilers. This action is necessary to prevent failure of the windshield wiper assembly, which could result in loss of visibility, damage to the propeller(s) and/or engine(s), or penetration of the fuselage skin and consequent rapid depressurization of the airplane. This action is intended to address the identified unsafe condition.
