Requirement:       1. Add the information contained in one of the following documents to the LIMITATIONS section of the Flight Manual:
                     a. FAA AD 98-25-02 Amdt 39-10924 Appendix titled "Power-Up Procedures for Skywatch SKY497 Installations with Top-Mounted Antenna".
                     b. BFGoodrich Alert Service Bulletin SB #78A dated 21 October 1998.

             This task may be accomplished by inserting a copy of either document into the limitations section of the Flight Manual.

             The introduction of software version 16, 1.7 or 1.8 provides an equivalent level of safety to this requirement and the statement may be removed form the flight manual.
             Note 2:  The limitations added to the Flight Manual require the pilot to verify the antenna configuration of the SKY497 each time the system is powered up.
                2. If an incorrect antenna configuration is found during any of the power-up procedures specified in the Flight Manual limitations required by this Directive, remove the SKY497 from service.
             Note 3:  FAA AD 98-25-02 Amdt 39-10924 refers.
Compliance:     1. Remains unchanged as "Within 25 hours time in service from the effective date of the original issue of Directive".
                2. Prior to further flight.
             This Amendment becomes effective on 21 December 2006.
Background:  The FAA has been advised of numerous reports of internal component failure of SKY497 installations which changes the antenna configuration from a top to a bottom mount.  The change in configuration would result in target indications appearing on the incorrect side
