probe P/N 2015G2H2H-8(  ).
                For Requirement 2 - As of the effective date of this Amendment.
                This Amendment becomes effective on 4 April 2008.

Background:  The ANAC has received reports of moisture being found in the pneumatic passage between the pitot port and the pressure sensors in the air data smart probes.  That moisture may freeze and block the sensors, causing erroneous information to the Air Data System.
             Since this condition may affect the safety of the aeroplane, the original issue of this Directive required the repetitive inspection of the air data smart probes for moisture and, if necessary, the removal of any accumulated moisture.
             This Amendment continues the repetitive inspection of the probes until the probe is optionally replaced with a probe P/N 2015G2H2H-8(  ).
             The original issue of this Directive became effective on 4 April 2007.
