Airtell International, Inc., Centaurus Model C3-100 Ground Proximity Warning System (GPWS), as Installed in Various Airplanes
Centaurus Model C3-100 ground proximity warning system (GPWS) equipment, as installed in, but not limited to, the following airplanes, certificated in any category: Beech 99 series airplanes; Beech 200 series airplanes; Dassault Aviation Model Mystere-Falcon 200 series airplanes; EMBRAER (Empresa Brasileira de Aeronautica S.A.) EMB-110 series airplanes; Fairchild Aircraft Model SA226-TC series airplanes; Fairchild Aircraft Model SA227-AT series airplanes; and Grumman Model G-73 Mallard airplanes.
This amendment adopts a new airworthiness directive (AD), applicable to all Airtell International, Inc., Centaurus Model C3-100 GPWS equipment that is installed on any type of airplane, that requires replacement of this equipment with a similar type of equipment that meets specific performance requirements. This amendment is prompted by results of an investigation, which revealed that, under certain circumstances, the Centaurus GPWS equipment does not provide the flight crew with aural warnings to indicate that the airplane is descending. The actions specified by this AD are intended to prevent failure of the GPWS equipment to provide such aural warnings. If the flight crew relies on receiving such warnings and the GPWS equipment fails to provide those warnings, the ability of the flight crew to prevent the airplane from impacting the ground may be inhibited.
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.
