SUPPLEMENTARY INFORMATION:
Conclusion
We reviewed the available data and
determined that air safety and the
public interest require adopting the AD
as proposed.
SUMMARY: We are adopting a new
airworthiness directive (AD) for the
products listed above. This AD results
from mandatory continuing
airworthiness information (MCAI)
issued by an aviation authority of
another country to identify and correct
an unsafe condition on an aviation
product. The MCAI describes the unsafe
condition as:
This Airworthiness Directive (AD) is
prompted due to a potential problem with
the tail landing gear locking mechanism of
PC–6 series aircraft.
Investigation, carried out after an incident
report, determined that both screws of the
tail-wheel locking mechanism had ruptured,
rendering the mechanism inoperative.
In order to address this situation, the
present AD requires you replace the two bolts
of the tail-wheel locking mechanism with
new ones, having higher shear strength, and
install a warning placard on the tail-wheel
mudguard.
The actions specified by this AD are
intended to prevent, on take-off or landing
runs, possible hazards associated with loss of
directional control.
This Airworthiness Directive (AD) is
prompted due to a potential problem with
the tail landing gear locking mechanism of
PC–6 series aircraft.
Comments
We gave the public the opportunity to
participate in developing this AD. We

Investigation, carried out after an incident
report, determined that both screws of the
tail-wheel locking mechanism had ruptured,
rendering the mechanism inoperative.
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would
apply to the specified products. That
NPRM was published in the Federal
Register on May 1, 2008 (73 FR 23993).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:

Differences Between This AD and the
MCAI or Service Information
We have reviewed the MCAI and
related service information and, in
general, agree with their substance. But
we might have found it necessary to use
different words from those in the MCAI
to ensure the AD is clear for U.S.
operators and is enforceable. In making
these changes, we do not intend to differ
substantively from the information
provided in the MCAI and related
service information.
We might also have required different
actions in this AD from those in the
MCAI in order to follow FAA policies.
Any such differences are highlighted in
a NOTE within the AD.
Costs of Compliance
Based on the service information, we
estimate that this AD will affect 50
products of U.S. registry. We also
estimate that it will take about 3 workhours per product to comply with basic
requirements of this AD. The average
labor rate is $80 per work-hour.
Required parts will cost about $120 per
product.
Based on these figures, we estimate
the cost of this AD to the U.S. operators
to be $18,000 or $360 per product.
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
section 106, describes the authority of
the FAA Administrator. ‘‘Subtitle VII:
Aviation Programs,’’ describes in more
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in ‘‘Subtitle VII,
Part A, Subpart III, Section 44701:
General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for

35912
Federal Register / Vol. 73, No. 123 / Wednesday, June 25, 2008 / Rules and Regulations
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We determined that this AD will not
have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
(3) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD Docket.
Examining the AD Docket
You may examine the AD docket on
the Internet at https://
www.regulations.gov; or in person at the
Docket Management Facility between 9
a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The AD
docket contains the NPRM, the
regulatory evaluation, any comments
received, and other information. The

Background
The America Creating Opportunities
to Meaningfully Promote Excellence in
Technology, Education, and Science
(COMPETES) Act, Public Law 110–69,
was enacted on August 9, 2007, to
invest in innovation through research
and development and to improve the
competitiveness of the United States.
Section 3012 of the COMPETES Act
established TIP for the purpose of
assisting United States businesses and
institutions of higher education or other
organizations, such as national
laboratories and nonprofit research
institutions, to support, promote, and
accelerate innovation in the United
States through high-risk, high-reward
research in areas of critical national
need. High-risk, high-reward research is
research that has the potential for

yielding transformational results with
far-ranging or wide-ranging
implications; addresses areas of critical
national need that support, promote,
and accelerate innovation in the United
States and is within NIST’s areas of
technical competence; and is too novel
or spans too diverse a range of
disciplines to fare well in the traditional
peer review process. Section 3012(f) of
the America COMPETES Act requires
the NIST Director to promulgate
regulations implementing the TIP.
NIST published a notice of proposed
rulemaking with a request for public
comments in the Federal Register on
March 7, 2008 (46 FR 12305) to seek
public comment on proposed
regulations implementing TIP, which
included policies and procedures for the
award of financial assistance (grants
and/or cooperative agreements) under
TIP. The notice specifically sought
comment on how NIST should
determine if ‘‘reasonable and thorough
efforts have been made to secure
funding from alternative funding
sources and no other alternative funding
sources are reasonably available.’’ In
addition, the Federal Register notice
informed the public that NIST was
revising the heading of Subchapter K of
its regulations to accurately reflect the
current contents of that subchapter.
The comment period closed on April
21, 2008.
In response to the comment received
regarding the ownership of invention
rights in the course of a bankruptcy or
dissolution, and also to correct the
following typographical errors and
inconsistencies and clarify terminology
found in the proposed rule, NIST makes
the following changes from the
proposed rule:
In the Table of Contents, the titles of
section 296.11 and the title of Subpart
C were revised to be consistent with the
titles of that section and subpart within
the body of the rule. The title of section
296.20 in both the Table of Contents and
the body of the rule was changed to be
consistent with the capitalization format
used in the remainder of the rule.
In paragraphs 296.2(f) and (z), the
definitions of critical national need and
societal challenge, respectively, the
word ‘‘demands’’ was changed to
‘‘justifies’’ to better characterize the
government’s role in responding to
societal challenges.
In paragraph 296.4(c), the second
sentence was corrected to reflect the fact
that the referenced Procurement
Standards are in part 14 of subtitle A of
title 15.
Paragraph 296.11(b)(4) was revised to
clarify under what situations that
paragraph applies.

In section 296.22, the order of the
award criteria found in paragraphs (d)
and (e) was revised to be consistent with
the order of the evaluation criteria
found in section 296.21.
In paragraph 296.21(b)(1), the first
sentence was corrected by adding the
word ‘‘knowledge’’ after ‘‘United States
science and technology’’ to be
consistent with newly redesignated
paragraph 296.22(e).
Summary of Public Comments Received
by NIST in Response to the May 7,
2008, Proposed Regulations, and NIST’s
Response to Those Comments
NIST received five responses to the
request for comments. Two responses
were from for-profit companies. One
response was from a United States
Senator. One response was from an
individual. One response was from an
industry association. A detailed analysis
of the comments follows.
General Comments
Comment: One commenter expressed
personal views about NIST.
Response: This comment is outside
the scope of this rulemaking.
Comment: One commenter stated that
they found it difficult to understand
how NIST staff will identify areas that
demand government attention. Another
commenter highlighted their industry’s
commitment to high-risk, high-reward
research, including a few example of
their work to transform some of the
Nation’s major societal challenges. The
commenter further stated that the
examples provided amplify that their
specific industry should be considered
as an area of critical national need.
Response: As indicated in the March
7, 2008 Federal Register notice, in
determining which areas of critical
national need will be addressed in a
competition, TIP may solicit input from
within NIST, from the TIP Advisory
Board, and from the public. TIP may
engage experts in scientific and
technology policy to ensure that the
areas of critical national need that will
be considered are those that entail
significant societal challenges that are
not already being addressed by others
and could be addressed through highrisk, high-reward research. Specific
societal challenges within selected areas
of critical national need will be the
focus of TIP funding.
Comment: One commenter raised a
question about a business review
indicating that the new legislation
appears to remove the impetus and need
to commercialize to capture the
economic value potentially created.
Response: The TIP legislation does
not include a commercialization

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on May 1, 2008 (73 FR
23993). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
This Airworthiness Directive (AD) is prompted due to a potential
problem with the tail landing gear locking mechanism of PC-6 series
aircraft.
Investigation, carried out after an incident report, determined
that both screws of the tail-wheel locking mechanism had ruptured,
rendering the mechanism inoperative.
In order to address this situation, the present AD requires you
replace the two bolts of the tail-wheel locking mechanism with new
ones, having higher shear strength, and install a warning placard on
the tail-wheel mudguard.
The actions specified by this AD are intended to prevent, on
take-off or landing runs, possible hazards associated with loss of
directional control.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
Based on the service information, we estimate that this AD will
affect 50 products of U.S. registry. We also estimate that it will take
about 3 work-hours per product to comply with basic requirements of
this AD. The average labor rate is $80 per work-hour. Required parts
will cost about $120 per product.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $18,000 or $360 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for
[[Page 35912]]
safety in air commerce. This regulation is within the scope of that
authority because it addresses an unsafe condition that is likely to
exist or develop on products identified in this rulemaking action.
Regulatory Findings
We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
government and the States, or on the distribution of power and
responsibilities among the various levels of government.
For the reasons discussed above, I certify this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979); and
(3) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria

Subject
(d) Air Transport Association of America (ATA) Code 32: Landing
Gear.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``This Airworthiness Directive (AD) is prompted due to a
potential problem with the tail landing gear locking mechanism of
PC-6 series aircraft.
Investigation, carried out after an incident report, determined
that both screws of the tail-wheel locking mechanism had ruptured,
rendering the mechanism inoperative.
In order to address this situation, the present AD requires you
replace the two bolts of the tail-wheel locking mechanism with new
ones, having higher shear strength, and install a warning placard on
the tail-wheel mudguard.
The actions specified by this AD are intended to prevent, on
take-off or landing runs, possible hazards associated with loss of
directional control.''
