Background

The Loran-C navigation system ceased transmitting usable signals on February 8, 2010. Because the Loran-C system ceased operation, the FAA intends to cancel all Loran-C Technical Standard Orders and revoke all associated Technical Standard Order Authorizations (TSOA).

The FAA database contains one (1) specific TSO requiring the Loran-C system as a means of navigation, and numerous TSOAs issued for the design and manufacture of Loran-C avionics equipment. This announcement serves as notice to all Loran-C TSOA holders that the FAA intends to cancel all TSOs (including active historical TSOs) and revoke all TSOAs for Loran-C avionics equipment.
