Airworthiness Directive · Amendment 39-10748 · Saab Model SAAB 2000 Series Airplanes
Saab Model SAAB 2000 Series Airplanes
Model SAAB 2000 series airplanes, as listed in Saab Service Bulletin 2000-23-017, dated March 10, 1997; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Saab Model SAAB 2000 series airplanes, that requires replacing the radio tuning units (RTU's) and associated components with new, improved parts. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent NAV/COM radios from simultaneously changing tuned frequencies and transponder codes due to a black screen failure or ``blanking'' of an RTU, which could result in loss of communications capability and air traffic control data.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
