Airworthiness Directives; Saab Model SAAB 2000 Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Saab Model SAAB 2000 series airplanes. This action requires repetitive visual inspections to detect whether the de- icing system boots on the horizontal stabilizer are inflating fully. It also requires modification of the stabilizer de-icing system tube as terminating action for the repetitive inspections. This amendment is prompted by reports indicating that condensational water may collect in the de-icing system tube, freeze in low temperatures, and keep the boots from inflating fully. The actions specified in this AD are intended to prevent such failure which, if not corrected, could keep the stabilizer de-icing system from operating properly, and consequently result in reduced controllability of the airplane.
