issue of this Directive required a check of the transponder Air/Ground discrete input connections and, in case of discrepancies, the accomplishment of corrective action.
             Since the original issue of this Directive was issued, the European Aviation Safety Agency (EASA) has advised that the Applicability of EASA AD 2009-0097 only referred to 'aeroplanes' in which the affected transponders could be installed, inadvertently implying that no helicopters could be affected.  Some helicopters (eg Sikorsky S-92) are also known to be equipped with the affected transponders and it has been determined that the unsafe condition addressed by that AD can also occur during taxiing (weight-on-wheels) of helicopters.

   Since the original issue of this Directive reflected the requirements of EASA AD 2009-0097, this Amendment expands the applicability to include helicopters.
   The original issue of this Directive became effective on 26 March 2010.
