MCAI AD which states that two cases of
cracks on a certain cargo hook lever
(lever) have been reported by the
manufacturer of the cargo hook. This
lever is a critical structural component
of the cargo hook, and a crack could
result in inadvertent loss of the cargo
hook load. The proposed AD would
require actions that are intended to
address the unsafe condition caused by
cracks in the cargo hook lever.

Discussion
EASA, which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Emergency AD No. 2007–0160–E, dated
June 7, 2007 (referred to after this as
‘‘the MCAI’’), to correct an unsafe
condition for these Italian-manufactured
products. The MCAI states that two
cases of cracks in the cargo hook lever
(lever), part number (P/N) 232–028–00,
have been reported by the manufacturer
of the cargo hook. The lever is a
component of the cargo hook, P/N 528–
010–01. This lever is a critical structural
component of the cargo hook, and a
crack could result in inadvertent loss of
the cargo hook load.
You may obtain further information
by examining the MCAI and service
information in the AD docket.
Relevant Service Information
Agusta has issued Alert Bollettino
Tecnico (ABT) No. 109EP–78, ABT No.
109S–12, and ABT No. 119–21, all dated
June 6, 2007. The actions described in
the MCAI are intended to correct the
same unsafe condition as that identified
in the service information.
dwashington3 on PROD1PC60 with PROPOSALS
FAA’s Determination and Proposed
Requirements
These products have been approved
by the aviation authority of Italy, and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with this State of Design
Authority, we have been notified of the
unsafe condition described in the MCAI
and service information. 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 these same type designs.
VerDate Nov<24>2008

Jkt 217001
Differences Between This AD and the
MCAI AD
We have reviewed the MCAI and, in
general, agree with its substance.
However, we have made the following
changes:
• Excluded the August 31, 2007
compliance date because that date has
passed;
• Excluded the Model A109LUH from
the applicability and do not reference
Agusta ABT No. 109L–006 because the
Model A109LUH helicopter is not on
the U.S. type certificate, H7EU;
• Added the Model AW119MKII to
the applicability;
• Proposed to require the use of a 10power or higher magnifying glass to
accomplish the visual inspections; and
• Excluded the kit installation P/N,
relying instead on the cargo hook and
lever P/N.
These differences are highlighted in the
‘‘Differences Between the FAA AD and
the MCAI AD’’ section in the proposed
AD.
Costs of Compliance
We estimate that this proposed AD
would affect about 26 helicopters on the
U.S. Registry with the cargo hook. We
also estimate that it would take about 10
minutes to inspect each cargo hook for
a crack, and about 1 work-hour to
replace a cracked cargo hook. The
average labor rate is $80 per work-hour.
Required parts would cost about $3,677
per cargo hook. Based on these figures,
we estimate the cost of the proposed AD
on U.S. operators to be $97,647 per year,
assuming that each affected helicopter
would require five inspections per
week, and that two cargo hooks would
have to be replaced each year.
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 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); 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 an economic evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

SUMMARY: We propose to adopt a new
airworthiness directive (AD) for Bell
Helicopter Textron Canada (BHTC)
Model 427 helicopters. This proposed
AD results from mandatory continuing
airworthiness information (MCAI)
originated by the aviation authority of
Canada to identify and correct an unsafe
condition on an aviation product.
Transport Canada, the aviation authority
of Canada, with which we have a
bilateral agreement, states that it has
been determined that the existing
hardware connecting the vertical fin to
the tail rotor gearbox needs to be
upgraded, to prevent the vertical fin
from becoming loose.
BHTC has received reports of loose
vertical fins discovered during
inspections. Investigation revealed that
the current vertical fin attachment
hardware may not provide adequate
clamp-up. If not corrected, the vertical
fin could become loose and cause
vibration, which could lead to
subsequent loss of control of the
helicopter. The proposed AD would
require actions that are intended to
address this unsafe condition.

states that two cases of cracks in the cargo hook lever (lever), part
number (P/N) 232-028-00, have been reported by the manufacturer of the
cargo hook. The lever is a component of the cargo hook, P/N 528-010-01.
This lever is a critical structural component of the cargo hook, and a
crack could result in inadvertent loss of the cargo hook load.
You may obtain further information by examining the MCAI and
service information in the AD docket.
Relevant Service Information
Agusta has issued Alert Bollettino Tecnico (ABT) No. 109EP-78, ABT
No. 109S-12, and ABT No. 119-21, all dated June 6, 2007. The actions
described in the MCAI are intended to correct the same unsafe condition
as that identified in the service information.
FAA's Determination and Proposed Requirements
These products have been approved by the aviation authority of
Italy, and are approved for operation in the United States. Pursuant to
our bilateral agreement with this State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information. 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 these same type
designs.
Differences Between This AD and the MCAI AD
We have reviewed the MCAI and, in general, agree with its
substance. However, we have made the following changes:
Excluded the August 31, 2007 compliance date because that
date has passed;
Excluded the Model A109LUH from the applicability and do
not reference Agusta ABT No. 109L-006 because the Model A109LUH
helicopter is not on the U.S. type certificate, H7EU;
Added the Model AW119MKII to the applicability;
Proposed to require the use of a 10-power or higher
magnifying glass to accomplish the visual inspections; and
Excluded the kit installation P/N, relying instead on the
cargo hook and lever P/N.
These differences are highlighted in the ``Differences Between the FAA
AD and the MCAI AD'' section in the proposed AD.
Costs of Compliance
We estimate that this proposed AD would affect about 26 helicopters
on the U.S. Registry with the cargo hook. We also estimate that it
would take about 10 minutes to inspect each cargo hook for a crack, and
about 1 work-hour to replace a cracked cargo hook. The average labor
rate is $80 per work-hour. Required parts would cost about $3,677 per
cargo hook. Based on these figures, we estimate the cost of the
proposed AD on U.S. operators to be $97,647 per year, assuming that
each affected helicopter would require five inspections per week, and
that two cargo hooks would have to be replaced each year.
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 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); 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 an economic evaluation of the estimated costs to comply
with this proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Agusta S.p.A.: Docket No. FAA-2008-0226; Directorate Identifier
2007-SW-35-AD.
Comments Due Date
(a) We must receive comments by April 22, 2009.
Other Affected ADs
(b) None.
Applicability
(c) This AD applies to Model A109E, A109S, A119, and AW119MKII
helicopters with cargo hook, part number (P/N) 528-010-01, and cargo
hook lever, P/N 232-028-00, installed, certificated in any category.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states that two cases of cracks in the lever, P/N 232-028-00, have
been reported by the
[[Page 12098]]
manufacturer of the cargo hook. The lever is a component of the
cargo hook, P/N 528-010-01. This lever is a critical structural
component of the cargo hook, and a crack could result in inadvertent
loss of the cargo hook load.
Actions and Compliance
(e) Before each cargo hook operation, visually inspect the cargo
hook lever, P/N 232-028-00, for any crack. Use a 10-power or higher
magnifying glass and inspect in the area depicted in Figures 1 and 2
of the following Agusta Alert Bollettino Tecnico (ABT), all dated
June 6, 2007:
(1) ABT No. 109EP-78 for Model A109E helicopters;
(2) ABT No. 109S-12 for Model A109S helicopters; or
(3) ABT No. 119-21 for Model A119 helicopters.
(f) If a crack is found in the lever, do not use the cargo hook
until the entire cargo hook is replaced with an airworthy cargo hook
with an uncracked lever.
Differences Between the FAA AD and the MCAI AD
(g) This AD differs from the MCAI AD in that we:
(1) Exclude the August 31, 2007 compliance date because that
date has passed;
(2) Exclude the Model A109LUH from the applicability and do not
reference Agusta ABT No. 109L-006 because the Model A109LUH
helicopter is not on the U.S. type certificate, H7EU;
(3) Add the Model AW119MKII to the applicability;
(4) Require the use of a 10-power or higher magnifying glass to
accomplish the visual inspections; and
(5) Exclude the kit installation P/N, relying instead on the
cargo hook and lever P/N.
Other Information
(h) Alternative Methods of Compliance (AMOCs): The Manager,
Safety Management Group, FAA, has the authority to approve AMOCs for
this AD, if requested using the procedures found in 14 CFR 39.19.
