Requirement:     1. For aeroplanes listed in Table 1 - Inspect the alternate static air source selector valve to assure that the part number identification placard is not obstructing the port as follows:
                   a. Adjust the pilot and copilot seats as far aft as possible.
                   b. Use a flashlight and mirror to inspect the alternate static air source selector valve to assure the port on the forward end of the valve is clearly visible and not covered by the part number identification placard.
                 2. For aeroplanes listed in Table 2 - Either:
                   a. Inspect the alternate static air source selector valve in accordance with Requirement 1, or
                   b. Inspect the aeroplane's maintenance records to determine if the alternate static air source selector valve has been replaced since 19 November 2007 with P/N 2013142-18, if the valve has not been replaced no further action is necessary.
              Note 3:  The Requirement 2.b. inspection and determination may be accomplished and certified for by the aeroplane operator, provided that they hold at least a private pilot's licence.
