Airborne Radar Altimeter Equipment (For Air Carrier Aircraft)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of intent to cancel Technical Standard Order (TSO)-C67, 
Airborne Radar Altimeter Equipment (For Air Carrier Aircraft).

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

SUMMARY: This notice announces the FAA's intent to cancel TSO-C67, 
Airborne Radar Altimeter Equipment (For Air Carrier Aircraft). The 
effect of the cancelled TSO will result in no new TSO-C67 design or 
production approvals. However, cancellation will not affect any current 
production of an existing TSO authorization (TSOA). Articles produced 
under an existing TSOA can still be installed per the existing 
airworthiness approvals, and all applications for new airworthiness 
approvals will still be processed.

DATES: Comments must be received on or before February 22, 2012.

FOR FURTHER INFORMATION CONTACT: Mr. Albert Sayadian, AIR-130, Federal 
Aviation Administration, 470 L'Enfant Plaza, Suite 4102, Washington, DC 
20024. Telephone (202) 385-4652, fax

SUPPLEMENTARY INFORMATION: 

Comments Invited

    You are invited to comment on the cancellation of the TSO-C67 by 
submitting written data, views, or arguments to the above address. 
Comments received may be examined, both before and after the closing 
date at the above address, weekdays except federal holidays, between 
8:30 a.m. and 4:30 p.m. The Director, Aircraft Certification Service, 
will consider all comments received on or before the closing date.

Background

    On November 15, 1960, the FAA published TSO-C67, Airborne Radar 
Altimeter Equipment (for air carrier aircraft). Since 1978, there have 
been no new applications for TSOA for TSO-C67. Our research indicates 
there are no authorized manufacturers currently manufacturing, 
advertising, or selling TSO-C67 compliant equipment. Therefore, given 
the obsolescence of the equipment, and the lack of industry interest in 
TSO-C67 product designs, we propose cancelling TSO-C67. Please note 
that TSO-C87, Airborne Low Range Radio Altimeter, is currently used for 
Radio Altimeter certification and is not affected by this action.

Susan J. M. Cabler,
Assistant Manager, Aircraft Engineering Division, Aircraft 
Certification Service.
