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 ensure correct installation of certain self- seal couplings in each nacelle, and corrective action, if necessary. This amendment also requires installation of a new clamp to the self- seal couplings. This action is necessary to prevent separation of the self-seal couplings, which could result in loss of engine oil pressure and a flight-crew-commanded engine shutdown. This action is intended to address the identified unsafe condition.
