Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires an inspection to detect chafing or damage to the electrical wire harnesses in the left and right wing fuel tanks, applicable corrective action(s) if necessary, and installation of harnesses. For certain airplanes, this AD also requires modifying the collector tank walls. This action is necessary to prevent chafing damage to the electrical wire harnesses in the left and right wing fuel tanks, which could cause misleading data and erroneous fuel pump cautions to be displayed to the flightcrew, and could result in electrical arcing with consequent increased potential for fire or explosion in the fuel tank. This action is intended to address the identified unsafe condition.
