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.

Lee Nguyen, AIR–130, Federal Aviation
Administration, 470 L’Enfant Plaza,

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
20:20 Mar 27, 2013
Jkt 229001
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
AGENCY:
VerDate Mar<15>2010
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.
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.

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
gerald.yakowenko@dot.gov. For legal
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 (https://www.fhwa.dot.gov/
construction/contracts/
waivers.cfm?id=79) on August 22nd.
The FHWA received five comments in
response to the publication. Two
