accuracy is to be achieved on long range 

flights. Use of INS and Global 

Positioning System (GPS) has rendered 

TSO-C68a systems obsolete. The FAA 

has no record of any applications for 

TSO-C68a since it was published in 

1983. Given the obsolescence of the 

equipment and the lack of industry 

interest in TSO-C68a product designs, 

we propose cancelling TSO-C68a.

Federal Aviation Administration 

Technical Standard Order (TSO) 

C-122a, Equipment That Prevent 

Blocked Channels Used in Two-Way 

Radio Communications Due to 

Simultaneous Transmissions 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice. 

SUMMARY: This notice announces the 

FAA’s intent to cancel TSO-C122a, 

Equipment That Prevent Blocked 

Channels Used in Two-Way Radio 

Communications Due to Simultaneous 

Transmissions. The effect of the 

cancelled TSO will not affect design or 

production according to an existing TSO 

authorization (TSOA). Articles 

produced under an existing TSOA can 

still be installed according to existing 

airworthiness approvals and 

applications for new airworthiness 

installation approvals will still be 

processed. 

DATES: Comments must be received on 

or before July 23, 2012.

SUPPLEMENTARY INFORMATION: 

Comments Invited 

You are invited to comment on the 

proposed cancellation of the TSO 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 

In 1984, the FAA was petitioned to 

enact rulemaking requiring two-way 

radio communication systems 

employing anti-blocking and stuck 

microphone protection circuitry. Our 

response to this rulemaking petition was 

the issuance of TSO-C128, Devices that 

Prevent Blocked Channels Used in TwoWay Radio Communications Due to 

Unintentional Transmissions, for 

preventing blocked channels used in 

two-way radio communication due to 

unintentional transmissions. TSO-C128, 

and the subsequent revision, has proven 

effective and popular with VHF radio 

manufacturers. Since 1994, there has 

been only one application for TSOA for 

TSO-C122a. Therefore, we believe it is 

appropriate to cancel TSO-C122a, given 

the eventual obsolescence of TSO-C122a 

equipment and the lack of industry 

interest in new TSO-C122a product 

designs. We continue to coordinate with 

industry’s federal advisory committee 

through RTCA Special Committee (SC) 

226, Audio Systems and Equipment, for 

any new developments on other means 

being used to address blocked channels 

caused by simultaneous transmissions.

FHWA Environmental Excellence 

Awards. 

Background: In 1995 FHWA 

established the biennial Environmental 

Excellence Awards to recognize 

partners, projects and processes that use 

FHWA funding sources to go beyond 

environmental compliance and achieve 

environmental excellence. Awardees 

must make an outstanding contribution 

that goes beyond traditional 

transportation projects and that 

encourages environmental stewardship 

and partnerships to achieve a truly 

multi-faceted, environmentally sensitive 

transportation solution. 

Award: Anyone can nominate a 

project, process, person or group that 

has used Federal Highway 

Administration funding sources to make 

an outstanding contribution to 

transportation and the environment. 

The nominator is responsible for 

submitting an application via the FHWA 

Environmental Excellence Awards Web 

site that gives a summary of the 

outstanding accomplishments of the 

entry. The collected information will be 

used by FHWA to evaluate, showcase 

and enhance the public’s knowledge on 

incorporating environmental 

stewardship into the planning and 

project development process. 

Nominations will be reviewed by an 

independent panel of judges from
