Amdt 39-12819 and FAA Special Airworthiness Information Bulletin CE-03-21 refer.

           Compliance: For Requirement 1 - Remains unchanged as 'Within 12 months after the effective date of the original issue of this Directive'.

           For Requirement 2 - As of the effective date of this Amendment. This Amendment becomes effective on 12 June 2003.

           Background: The original issue of this Directive required replacement of any affected ADC with one that has a reprogrammed and tested CPU circuit card and circuit card assembly. The Directive was issued following a flight test that showed that these ADCs could display an unwarranted ADC flag in response to the aeroplane's "Normal/Alternate Air" static source selection capability. This could cause the flight crew to react to this incorrect flight information and possibly result in an unsafe operating condition.

           This Amendment is issued following advice from the United States Federal Aviation Administration that Saab 340 series aeroplanes were not affected.

           The original issue of this Directive became effective on 5 September 2002.
