                Note 2:  The words "as in force from time to time" require compliance with the most recent version of the referenced document.
                  2. Disable the Automatic Dependent Surveillance - Broadcast (ADS-B) function on TDR-94 transponders with P/N 622-9352-409 and TDR-94D transponders with P/N 622-9210-409 unless compliance with European Aviation Safety Agency (EASA) Acceptable Means of Compliance (AMC) 20-24 as in force from time to time or EASA Certification Specifications and Acceptable Means of Compliance for Airborne Communications, Navigation and Surveillance (CS-ACNS) as in force from time to time or United States of America Federal Aviation Administration (FAA) Code of Federal Regulations (CFR) 14CFR91.225 and 91.227 as in force from time to time has been demonstrated.
                  3. Transponders, identified by the Applicability Statement may not be installed in an aeroplane equipped with Honeywell AZ800 or AZ810 (all part numbers) ADC where the data bus interface between the Honeywell ADC and the transponder is providing the Selected Altitude data input to the transponder unless modified in accordance with Requirement 1.a.
               Note 3:  This Directive is not applicable to Avions de Transport Régional ATR-42 and ATR-72 aeroplanes on which the affected transponder and ADC installation has been done in accordance with an ATR design definition, although equipped with transponders and Honeywell AZ800 or AZ810 ADC as listed in the Applicability section of this Directive, since on these aeroplanes' original architecture, the Selected Altitude is not provided by the ADC.
               Note 4:  This Directive is not applicable to de Havilland Canada DHC-8 Series 100, 200 and 300 aeroplanes, all models, on which the affected transponder and ADC installation has been done in accordance with the applicable de Havilland Canada Type Design definition, although equipped with affected transponders and Honeywell AZ800 or AZ810 ADC as listed in the Applicability section of this Directive, are exempt from having to meet the requirements of this Directive, since on these aeroplanes' original architecture, the Selected Altitude is not provided by the ADC.  This exemption does not apply to aeroplanes that have been modified to enable a digital link between the air data computer and the transponder.
               Note 5:  EASA AD 2009-0173R1 is the basis for this AD.
Compliance:    For Requirement 1 - Within 60 days after the commencement date of this AD, unless previously
