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.
Issued in Washington, DC.
Susan J.M. Cabler,
Assistant Manager, Aircraft Engineering Division, Aircraft
Certification Service.
