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 testing of certain components of the emergency pitch trim system (EPTS), and corrective action, if necessary. This action is necessary to prevent faulty activation of the emergency pitch trim actuator (EPTA), which could cause damage to the elevator front spar, resulting in reduced structural integrity of the elevator and a non-functioning EPTS. This action is intended to address the identified unsafe condition.
