AD FAA-2011-1062

We are superseding an existing airworthiness directive (AD) for all Saab AB, Saab Aerosystems Model 340A (SAAB/SF340A) and SAAB 340B airplanes. That AD currently requires an inspection of the main landing gear (MLG) separation bolt harness for broken wires and corroded connectors, and corrective actions if necessary; and for certain airplanes, a modification of the MLG separation bolt's electrical harness. This new AD requires replacement of the separation bolt harness. This AD was prompted by reports of broken wires and corroded connectors in the SAAB 340 MLG emergency release system. We are issuing this AD to prevent improper release of the MLG during an emergency situation, possibly resulting in damage to the airplane during landing and injury to the occupants.
