Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain Saab Model SAAB 2000 series airplanes. This AD requires a one- time inspection to detect a broken terminal stud on a main relay of the electrical power generator, and corrective action if necessary. This AD is prompted by disconnection of an electrical power generator during an inspection flight, which was caused by a broken terminal stud on the main relay. We are issuing this AD to prevent a broken terminal stud on the main relay of an electrical power generator, which could reduce the redundancy of electrical power systems, result in increased pilot workload, and contribute to reduced controllability of the airplane.
