Federal Register / Vol. 77, No. 200 / Tuesday, October 16, 2012 / Proposed Rules
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 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 this 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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

Discussion
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2012–13,
dated April 10, 2012 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
A revision has been made to Part 2 of the
Canadair Regional Jet Maintenance
Requirements Manual (MRM), Airworthiness
Limitations (AWL), to introduce more
stringent inspection requirements for
continued airworthiness based on reanalysis, in-service data and/or fatigue
testing. Failure to comply with these revised
AWL items could lead to an unsafe
condition.
This [TCCA] AD is issued to ensure that
fatigue cracking of these affected components
[and consequent loss of airplane structural
integrity] is detected and corrected.
Required actions include revising the
maintenance program by incorporating
the revised inspection requirements
specified in certain temporary revisions
to Appendix B—Airworthiness
Limitations, of Part 2 of the Bombardier
CL–600–2B19 Maintenance
Requirements Manual (MRM). You may
obtain further information by examining
the MCAI in the AD docket.

FAA’s Determination and Requirements
of This Proposed AD
This product has been approved by
the aviation authority of another
country, and is approved for operation
in the United States. Pursuant to our
bilateral agreement with the State of
Design Authority, we have been notified
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all pertinent
information and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 575 products of U.S.
registry. We also estimate that it would
take about 1 work-hour per product to
comply with the basic requirements of
this proposed AD. The average labor
rate is $85 per work-hour. Based on
these figures, we estimate the cost of the
proposed AD on U.S. operators to be
$48,875, or $85 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.

Federal Register / Vol. 77, No. 200 / Tuesday, October 16, 2012 / Proposed Rules
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 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 this 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);
3. Will not affect intrastate aviation in
Alaska; and
4. 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.

Discussion
We propose to adopt a new AD for all
Brantly B–2, B–2A, and B–2B
helicopters with an M/R blade, part
number (P/N) 248–101, 248–202, or
248–404. This proposed AD is prompted
by a 2007 accident in New Zealand in
which a large inboard section of the M/
R blade of a Brantly B–2B helicopter
separated from the helicopter during
flight. Laboratory analysis concluded
that the M/R blade failure was caused
by hydrocarbon contaminants inside the
blade’s skin-to-foam bond and that the
fracture originated near the blade’s
trailing edge. There were three other
reports of portions of M/R blades
separating during flight and another five
reports of M/R blades having cracks or
other defects that were found during
inspections.
FAA’s Determination
We are proposing this AD because we
evaluated all known relevant
information and determined that an
unsafe condition exists and is likely to
exist or develop on other products of
these same type designs.
Related Service Information
We reviewed Brantly International
Inc. Service Bulletin No. 111, dated
February 10, 2011 (SB 111). The bulletin

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2012-13, dated April 10, 2012 (referred to after this as ``the MCAI''),
to correct an unsafe condition for the specified products. The MCAI
states:
A revision has been made to Part 2 of the Canadair Regional Jet
Maintenance Requirements Manual (MRM), Airworthiness Limitations
(AWL), to introduce more stringent inspection requirements for
continued airworthiness based on re-analysis, in-service data and/or
fatigue testing. Failure to comply with these revised AWL items
could lead to an unsafe condition.
This [TCCA] AD is issued to ensure that fatigue cracking of
these affected components [and consequent loss of airplane
structural integrity] is detected and corrected.
Required actions include revising the maintenance program by
incorporating the revised inspection requirements specified in certain
temporary revisions to Appendix B--Airworthiness Limitations, of Part 2
of the Bombardier CL-600-2B19 Maintenance Requirements Manual (MRM).
You may obtain further information by examining the MCAI in the AD
docket.

The actions described in this service information are intended to
correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 575 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $48,875, or $85 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.
[[Page 63284]]
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 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 this 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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
List of Subjects in 14 CFR Part 39
