DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

Airworthiness Approval for Aircraft 

Forward-Looking Windshear and 

Turbulence Radar Systems 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Request for comment. 

SUMMARY: This notice announces the 

proposed development of an advisory 

circular addressing airworthiness 

approval for aircraft forward-looking 

windshear and turbulence radar 

systems. The planned advisory circular 

would address installation guidance for 

these functionalities in Technical 

Standard Order (TSO)-C63d, Airborne 

Weather Radar Equipment. The 

objective is to leverage the installation 

specific guidance from the System Level 

Requirements (SLR) 10.2 recommended 

by the Forward-Looking Windshear 

Detection System Working Group and 

the generic issue papers on turbulence 

detection to publish an advisory 

circular. (In order for the public to 

comment on our proposal, they will 

need to have access to SLR 10.2 and the 

issue papers.) 

DATES: Request comments and interest 

in participating by April 29, 2013. 

FOR FURTHER INFORMATION CONTACT: Mr. 

Lee Nguyen, AIR–130, Federal Aviation 

Administration, 470 L’Enfant Plaza, 

Suite 4102, Washington, DC 20024. 

Telephone (202) 385–4676, fax (202)

SUPPLEMENTARY INFORMATION: 

Background 

Use of radar for forward-looking 

windshear and turbulence detection was 

previously addressed as additional 

functionality added to TSO–C63c, 

Airborne Weather and Ground Mapping 

Pulsed Radars. The FAA and industry 

collaborated on the end-to-end 

requirements for the design and 

installation of the forward-looking 

windshear detection system with SLR 

10.2 and the turbulence detection 

function issue papers. With the 

publication of TSO–C63d, which added 

the forward-looking windshear and 

turbulence detection requirements, the 

design requirements are deleted from 

the TSO functionality. 

Issue 

The design requirements are 

standardized and incorporated in TSO– 

C63d; however, use of the SLR 10.2 

documentation and the associated issue 

papers were not eliminated because 

guidance is still needed for the 

installation and airworthiness 

certification of these systems, which is 

not covered by TSO–C63d. 

Proposal 

The FAA proposes developing an 

advisory circular to address installation 

guidance for TSO–C63d predictive 

windshear and turbulence detection 

equipment. The goal is to combine the 

installation specific guidance from SLR 

10.2 and existing generic issue papers 

into an approved coordinated advisory 

circular. Additionally, the FAA would 

update the existing guidance as 

appropriate, based on experience with 

the existing guidance and industry 

input. 

Comment and Participation Invited 

The FAA requests comment on the 

proposed AC to provide installation 

guidance for forward-looking windshear 

and turbulence detection radar systems. 

If the FAA proceeds with development 

of the AC, we envision collaborating 

with industry when drafting the 

guidance. As such, we request 

interested participants in a working 

group to develop the AC to respond to 

the person listed in the ‘‘For Further 

Information Contact’’ paragraph. 

Issued in Washington, DC, on March 25,

Buy America Waiver Notification 

AGENCY: Federal Highway 

Administration (FHWA), DOT. 

ACTION: Notice. 

SUMMARY: This notice provides 

information regarding the FHWA’s 

finding that a Buy America waiver is 

appropriate for the use of non-domestic 

iron and steel products in GenSet diesel 

engine and air compressor for a 

Congestion Mitigation and Air Quality 

(CMAQ) project in the Commonwealth 

of Kentucky. 

DATES: The effective date of the waiver 

is March 29, 2013. 

FOR FURTHER INFORMATION CONTACT: For 

questions about this notice, please 

contact Mr. Gerald Yakowenko, FHWA 

Office of Program Administration, (202) 

366–1562, or via email at

questions, please contact Mr. Michael 

Harkins, FHWA Office of the Chief 

Counsel, (202) 366–4928, or via email at

Background 

The FHWA’s Buy America policy in 

23 CFR 635.410 requires a domestic 

manufacturing process for any steel or 

iron products (including protective 

coatings) that are permanently 

incorporated in a Federal-aid 

construction project. The regulation also 

provides for a waiver of the Buy 

America requirements when the 

application would be inconsistent with 

the public interest or when satisfactory 

quality domestic steel and iron products 

are not sufficiently available. This 

notice provides information regarding 

the FHWA’s finding that a Buy America 

waiver is appropriate to use some nondomestic iron and steel products in 

GenSet diesel engine and air compressor 

for CMAQ project in the Commonwealth 

of Kentucky. 

In accordance with Division A, 

section 122 of the ‘‘Consolidated and 

Further Continuing Appropriations Act, 

2012’’ (Pub. L. 112–284), the FHWA 

published a notice of intent to issue a 

waiver on its Web site for iron and steel 

products in GenSet diesel engine and air 

compressor (http://www.fhwa.dot.gov/ 

construction/contracts/ 

waivers.cfm?id=79) on August 22nd. 

The FHWA received five comments in 

response to the publication. Two
