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.

**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.

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 thatPrevent 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.

**SUPPLEMENTARY INFORMATION :**  Title: 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.
