Approval of this change in type design applies to the above model aircraft equipped with a flight management computer (FMC), which meets AC 90-45A.

A copy of this Certificate and the FAA Approved Airplane Flight Manual Supplement (AFMS) must be maintained as part of the permanent records for the modified aircraft. A system self test as specified in Document No. 060-4167-004, production ground test procedures, shall be performed at intervals not to exceed 6,000 flight hours or 15 months, which ever comes first.
