SUMMARY: We propose to adopt a new
airworthiness directive (AD) for all Air
Tractor, Inc. Models AT–602, AT–802,
and AT–802A airplanes. This proposed
AD would require you to repetitively
inspect the engine mount for any cracks,
repair or replace any cracked engine
mount, and report any cracks found to
VerDate Aug<31>2005

the FAA. This proposed AD results from
reports of cracked engine mounts. We
are proposing this AD to detect and
correct cracks in the engine mount,
which could result in failure of the
engine mount. Such failure could lead
to separation of the engine from the
airplane.
DATES: We must receive comments on
this proposed AD by June 27, 2006.

beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,

information you provide. We will also
post a report summarizing each
substantive verbal contact we receive
concerning this proposed AD.
Discussion
We received two reports from Air
Tractor, Inc. of cracked engine mounts
resulting from fatigue. One report was
for a Model AT–602 airplane. The
specific airplane model with the other
crack is unverified. This AD applies to
Air Tractor, Inc. Models AT–602, AT–
802, and AT–802A airplanes due to
design similarity.
A cracked engine mount, if not
detected and corrected, could result in
failure of the engine mount. Such failure
could lead to separation of the engine
from the airplane.
Relevant Service Information
We have reviewed Snow Engineering
Co. Service Letter #253, dated December
12, 2005.
The service information describes
procedures for performing a visual
inspection for cracks of the engine
mount and requesting a repair scheme
from the manufacturer.
Snow Engineering Co. has a licensing
agreement with Air Tractor, Inc. that
allows them to produce technical data
to use for Air Tractor, Inc. products.
FAA’s Determination and Requirements
of the Proposed AD
We are proposing this AD because we
evaluated all information and
determined the unsafe condition
described previously is likely to exist or
develop on other products of the same
type design. This proposed AD would
require you to repetitively inspect the
engine mount for any cracks, repair or
replace any cracked engine mount, and
report any cracks found to the FAA. To
repair a cracked engine mount, you
would obtain an FAA-approved repair
scheme from Air Tractor, Inc. following
the instructions in the service
information.
Costs of Compliance
We estimate that this proposed AD
would affect 368 airplanes in the U.S.
registry.
We estimate the following costs to do
the proposed inspection of the engine
mount for cracks:

Federal Register / Vol. 71, No. 84 / Tuesday, May 2, 2006 / Proposed Rules
Total cost per
airplane per
inspection
Labor cost
Parts cost
1.5 work hours × $80 per hour = $120 ............................................
Not Applicable .............................
We have no way of determining the
number of airplanes that may need
repair/replacement of the engine mount
as a result of the proposed inspection.
We have no way of determining the cost
of an engine mount repair. To replace
the engine mount would take 81 work
hours at $80 per hour (estimated total
labor = $6,480), parts cost of $3,982, and
a total replacement cost of $10,462 per
airplane.
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
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 have determined that this
proposed AD would not have federalism
implications under Executive Order
13132. This proposed AD would 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 that the proposed regulation:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
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 proposed AD and placed it in the
AD docket.
Examining the AD Docket
You may examine the AD docket that
contains the proposed AD, the
regulatory evaluation, any comments
received, and other information on the
Internet at https://dms.dot.gov; or in
person at the Docket Management
Facility between 9 a.m. and 5:00 p.m.,
Monday through Friday, except Federal
holidays. The Docket Office (telephone
(800) 647–5227) is located at the street
address stated in the ADDRESSES section.
Comments will be available in the AD
docket shortly after receipt.

ADDRESSES:
Background on Viticultural Areas
TTB Authority
Section 105(e) of the Federal Alcohol
Administration Act (the FAA Act, 27
U.S.C. 201 et seq.) requires that alcohol
beverage labels provide consumers with
adequate information regarding a
product’s identity and prohibits the use
of misleading information on those
labels. The FAA Act also authorizes the
Secretary of the Treasury to issue
regulations to carry out its provisions.
The Alcohol and Tobacco Tax and
Trade Bureau (TTB) administers these
regulations.
Part 4 of the TTB regulations (27 CFR
part 4) allows the establishment of
distinct viticultural areas and the use of
their names as appellations of origin on
wine labels and in wine advertisements.
Part 9 of the TTB regulations (27 CFR
part 9) contains the list of approved
viticultural areas.
Definition
Section 4.25(e)(1)(i) of the TTB
regulations (27 CFR 4.25(e)(1)(i)) defines
a viticultural area for American wine as
a delimited grape-growing region
distinguishable by geographical
features, the boundaries of which have
been recognized and defined in part 9
of the regulations. These designations
allow vintners and consumers to
attribute a given quality, reputation, or
other characteristic of a wine made from
grapes grown in an area to its
geographical origin. The establishment
of a viticultural area allows vintners to
more accurately describe the origin of
their wines to consumers and helps
consumers to identify wines they may
purchase. However, the establishment of
a viticultural area is neither an approval
nor an endorsement by TTB of the wine
produced in that area.
FOR FURTHER INFORMATION CONTACT:
Requirements
SUPPLEMENTARY INFORMATION:
Section 4.25(e)(2) of the TTB
regulations outlines the procedure for
proposing an American viticultural area
and provides that any interested party
may petition TTB to establish a grapegrowing region as a viticultural area.

Discussion
We received two reports from Air Tractor, Inc. of cracked engine
mounts resulting from fatigue. One report was for a Model AT-602
airplane. The specific airplane model with the other crack is
unverified. This AD applies to Air Tractor, Inc. Models AT-602, AT-802,
and AT-802A airplanes due to design similarity.
A cracked engine mount, if not detected and corrected, could result
in failure of the engine mount. Such failure could lead to separation
of the engine from the airplane.
Relevant Service Information
We have reviewed Snow Engineering Co. Service Letter 253,
dated December 12, 2005.
The service information describes procedures for performing a
visual inspection for cracks of the engine mount and requesting a
repair scheme from the manufacturer.
Snow Engineering Co. has a licensing agreement with Air Tractor,
Inc. that allows them to produce technical data to use for Air Tractor,
Inc. products.
FAA's Determination and Requirements of the Proposed AD
We are proposing this AD because we evaluated all information and
determined the unsafe condition described previously is likely to exist
or develop on other products of the same type design. This proposed AD
would require you to repetitively inspect the engine mount for any
cracks, repair or replace any cracked engine mount, and report any
cracks found to the FAA. To repair a cracked engine mount, you would
obtain an FAA-approved repair scheme from Air Tractor, Inc. following
the instructions in the service information.
Costs of Compliance
We estimate that this proposed AD would affect 368 airplanes in the
U.S. registry.
We estimate the following costs to do the proposed inspection of
the engine mount for cracks:
[[Page 25794]]
----------------------------------------------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane per Total cost on U.S. operators for
inspection initial inspection
----------------------------------------------------------------------------------------------------------------
1.5 work hours x $80 per hour = Not Applicable........ $120 368 x $120 = $44,160
$120.
----------------------------------------------------------------------------------------------------------------
We have no way of determining the number of airplanes that may need
repair/replacement of the engine mount as a result of the proposed
inspection. We have no way of determining the cost of an engine mount
repair. To replace the engine mount would take 81 work hours at $80 per
hour (estimated total labor = $6,480), parts cost of $3,982, and a
total replacement cost of $10,462 per airplane.
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 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 have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 that the proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket that contains the proposed AD, the
regulatory evaluation, any comments received, and other information on
the Internet at https://dms.dot.gov; or in person at the Docket
