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 installation of a new circuit breaker and related wiring, and relocation of circuit breaker 12FG, if applicable. This action is necessary to prevent loss of the nose wheel steering and reduced controllability of the airplane on the ground. This action is intended to address the identified unsafe condition.
