Background

    Because the Omega navigation system ceased operation on September 
30, 1997, the FAA intends to cancel all Omega Technical Standard Orders 
(TSOs) and revoke all associated Omega Technical Standard Order 
Authorizations (TSOAs). Currently, the FAA database contains three TSOs 
and numerous TSOAs for the design and manufacture of Omega avionics 
equipment. This announcement serves as notice to all Omega TSOA holders 
that the FAA intends to cancel all TSOs (including active historical 
TSOs) and revoke all TSOAs for Omega avionics equipment. The affected 
TSOs are as follows:

TSO-C94, Airborne Omega Receiving Equipment;
TSO-C94a, Omega Receiving Equipment operating within the Radio 
Frequency Range of 10.2 to 13.6 Kilohertz; and
TSO-C 120, Airborne Area Navigation Equipment Using Omega /VLF Inputs.
