Airborne Omega Receiving Equipment

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of cancellation of: (1) Omega navigation system 
Technical Standard Orders (TSO); and (2) the revocation of Omega 
navigation system TSO Authorizations (TSOA).

-----------------------------------------------------------------------

SUMMARY: This notice announces the cancellation of Technical Standard 
Orders (TSO) C-94, Airborne Omega Receiving Equipment; TSO-C94a, Omega 
Receiving Equipment Operating Within the Radio Frequency Range of 10.2 
to 13.6 Kilohertz; and TSO-C120, Airborne Area Navigation Equipment 
Using Omega/VLF Inputs. The effect of the cancelled TSOs will result in 
the revocation of all Technical Standard Order Authorizations issued 
for the production of those navigational systems. These actions are 
necessary because the Omega Navigation System ceased operation on 
September 30, 1997.

SUPPLEMENTARY INFORMATION:

Comments Invited

    You are invited to comment on the cancellation of the three (3) 
TSOs and the revocation of those associated TSOAs by submitting written 
data, views, or arguments to the above address. Comments received may 
be examined, both before and after the closing date, in Room 815 at the

Background

    The Omega navigation system ceased operation on September 30, 1997. 
Because the Omega system has been decommissioned for over 10 years, the 
FAA intends to cancel all Omega Technical Standard Orders and revoke 
all associated Technical Standard Order Authorizations (TSOA).
    The FAA database contains three (3) specific TSOs for equipment 
based on the Omega system as a means of navigation, and numerous TSOAs 
issued for the design and manufacture of Omega avionics equipment. This 
announcement serves as notice to all Omega TSOA holders that the FAA is 
cancelling all TSOs (including active historical TSOs) and revoking all 
TSOAs for Omega avionics equipment.
