AGENCY: Federal Aviation
Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for
comments.
SUMMARY: We are adopting a new
airworthiness directive (AD) for Bell
Helicopter Textron Canada (Bell) Model
407 and 427 helicopters. This AD
results from a mandatory continuing
airworthiness information (MCAI) AD
issued by the aviation authority of
Canada. The MCAI AD states that,
during a preflight check, it was observed
that the swashplate link assembly
bearing had moved in the lever race,
making contact with the swashplate
support. The MCAI also states that
further investigation revealed that the
bearing had not been staked correctly
during manufacture. That condition, if
not detected, could result in failure of
a bearing, failure of the swashplate link
assembly, and subsequent loss of
control of the helicopter.
DATES: This AD becomes effective on
November 16, 2009.
We must receive comments on this
AD by December 29, 2009.
ADDRESSES: You may send comments by
any of the following methods:

SUPPLEMENTARY INFORMATION:
Discussion
Transport Canada, which is the
aviation authority for Canada, has
issued AD No. CF–2009–14, dated April
15, 2009 to correct an unsafe condition
for Bell Model 407 helicopters, serial
number (S/N) 53000 through 53887,
53890 through 53916, 53918, 53920,
53921, 53923 through 53926, and 53928;
and Model 427 helicopters, S/N 56001
through 56074, 58001, and 58002, with
an anti-drive link assembly, part
number (P/N) 406–010–432–101, that
has a serial number prefix of ‘‘TI’’ or
‘‘TIFS.’’ Transport Canada states that
during a preflight check, it was observed
that the swashplate link assembly
bearing had moved in the lever race,
making contact with the swashplate
support. Transport Canada also states
that further investigation revealed that
the bearing had not been staked
correctly during manufacture and that
this situation, if not corrected, could
lead to loss of control of the helicopter.
You may obtain further information by
examining the MCAI AD and any
related service information in the AD
docket.

Related Service Information
Bell has issued Alert Service Bulletin
(ASB) No. 407–09–87, dated March 27,
2009, for the Model 407 helicopters and
ASB No. 427–09–24, Revision A, dated
March 30, 2009, for the Model 427
helicopters. The ASBs specify a onetime inspection of all anti-drive link
assemblies, P/N 406–010–432–101 with
a serial number prefix of ‘‘TI’’ or
‘‘TIFS,’’ to ensure that the bearing, P/N
406–310–403–101, is correctly and
securely staked in the link assembly.
The actions described in the MCAI AD
are intended to correct the same unsafe
condition as that identified in the ASBs.

FAA’s Evaluation and Unsafe Condition
Determination
These products have been approved
by the aviation authority of Canada, and
are approved for operation in the United
States. Pursuant to our bilateral
agreement with Canada, they have
notified us of the unsafe condition
described in the MCAI AD. We are
issuing this AD because we evaluated
all information provided by Transport
Canada and determined an unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This AD and the
MCAI AD
This AD differs from the MCAI AD as
follows:
• This AD requires compliance
within 10 hours time-in-service (TIS),
the MCAI AD requires compliance
within the next 10 flight hours, but no
later than 30 days from the effective day
of the MCAI AD, which was May 6,
2009; and
• This AD does not apply to Model
427 helicopters with S/N 58001 or
58002 because those serial-numbered
helicopters are not eligible for an FAA
certificate of airworthiness.

Comments Invited
This AD is a final rule that involves
requirements affecting flight safety, and
we did not precede it by notice and
opportunity for public comment.
However, we invite you to send us any
written data, views, or arguments
concerning this AD. Send your
comments to an address listed under the
ADDRESSES section of this AD. Include
‘‘Docket No. FAA–2009–1003;
Directorate Identifier 2009–SW–25–AD’’
at the beginning of your comments. We
specifically invite comments on the
overall regulatory, economic,
environmental, and energy aspects of
this AD. We will consider all comments
received by the closing date and may
amend this AD because of those
comments.
We will post all comments we
receive, without change, to https://
www.regulations.gov including any
personal information you provide. We
will also post a report summarizing each
substantive verbal contact we receive
about this AD.
FAA’s Determination of the Effective
Date
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
product(s) identified in this rulemaking
action.
An unsafe condition exists that
requires the immediate adoption of this
AD. We find that the risk to the flying
public justifies waiving notice and
comment prior to adoption of this rule
because the previously described
critical unsafe condition can adversely
affect the structural integrity of the
helicopter and the inspection must be
performed within 10 hours TIS.
Therefore, we have determined that
notice and opportunity for public
comment before issuing this AD are
impracticable and that good cause exists
for making this amendment effective in
fewer than 30 days.
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.
Therefore, I certify this AD:
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
Costs of Compliance
We estimate that this AD will affect
about 554 helicopters of U.S. registry.
We also estimate that it will take about
1 work-hour per helicopter to inspect
and replace, if necessary, the bearing or
the anti-drive link assembly. The
average labor rate is $80 per work-hour.
Required parts will cost about $400 for
a bearing or $3,517 for an anti-drive link
assembly, per helicopter. Based on these
figures, we estimate the cost of this AD
on U.S. operators will be $1,992,738
($3,597 per helicopter), assuming that
all anti-drive link assemblies are
replaced.

under the criteria of the Regulatory
Flexibility Act.
We prepared an economic evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

SUMMARY: We are rescinding an existing
airworthiness directive (AD) for the
products listed above. The existing AD
resulted 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:
On several occasions, leaks of the landing
gear emergency blowdown bottle have been
reported. Investigations revealed that the
leakage was located on the nut manometer
because of a design deficiency in the bottle
head.
If left uncorrected, the internal bottle
pressure could not be maintained to an
adequate level and could result in a
malfunction, failing to extend landing gears
during emergency situations.
Since issuance of that AD, we have
determined that the condition is not
unsafe.
DATES: This AD becomes effective
December 4, 2009.

58001, and 58002, with an anti-drive link assembly, part number (P/N)
406-010-432-101, that has a serial number prefix of ``TI'' or ``TIFS.''
Transport Canada states that during a preflight check, it was observed
that the swashplate link assembly bearing had moved in the lever race,
making contact with the swashplate support. Transport Canada also
states that further investigation revealed that the bearing had not
been staked correctly during manufacture and that this situation, if
not corrected, could lead to loss of control of the helicopter. You may
obtain further information by examining the MCAI AD and any related
service information in the AD docket.
Related Service Information
Bell has issued Alert Service Bulletin (ASB) No. 407-09-87, dated
March 27, 2009, for the Model 407 helicopters and ASB No. 427-09-24,
Revision A, dated March 30, 2009, for the Model 427 helicopters. The
ASBs specify a one-time inspection of all anti-drive link assemblies,
P/N 406-010-432-101 with a serial number prefix of ``TI'' or ``TIFS,''
to ensure that the bearing, P/N 406-310-403-101, is correctly and
securely staked in the link assembly. The actions described in the MCAI
AD are intended to correct the same unsafe condition as that identified
in the ASBs.
FAA's Evaluation and Unsafe Condition Determination
These products have been approved by the aviation authority of
Canada, and are approved for operation in the United States. Pursuant
to our bilateral agreement with Canada, they have notified us of the
unsafe condition described in the MCAI AD. We are issuing this AD
because we evaluated all information provided by Transport Canada and
determined an unsafe condition exists and is likely to exist or develop
on other products of the same type design.
Differences Between This AD and the MCAI AD
This AD differs from the MCAI AD as follows:
This AD requires compliance within 10 hours time-in-
service (TIS), the MCAI AD requires compliance within the next 10
flight hours, but no later than 30 days from the effective day of the
MCAI AD, which was May 6, 2009; and
This AD does not apply to Model 427 helicopters with S/N
58001 or 58002 because those serial-numbered helicopters are not
eligible for an FAA certificate of airworthiness.
Costs of Compliance
We estimate that this AD will affect about 554 helicopters of U.S.
registry. We also estimate that it will take about 1 work-hour per
helicopter to inspect and replace, if necessary, the bearing or the
anti-drive link assembly. The average labor rate is $80 per work-hour.
Required parts will cost about $400 for a bearing or $3,517 for an
anti-drive link assembly, per helicopter. Based on these figures, we
estimate the cost of this AD on U.S. operators will be $1,992,738
($3,597 per helicopter), assuming that all anti-drive link assemblies
are replaced.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD. We find that the risk to the flying public justifies waiving
notice and comment prior to adoption of this rule because the
previously described critical unsafe condition can adversely affect the
structural integrity of the helicopter and the inspection must be
performed within 10 hours TIS. Therefore, we have determined that
notice and opportunity for public comment before issuing this AD are
impracticable and that good cause exists for making this amendment
effective in fewer than 30 days.
Comments Invited
This AD is a final rule that involves requirements affecting flight
safety, and we did not precede it by notice and opportunity for public
comment. However, we invite you to send us any written data, views, or
arguments concerning this AD. Send your comments to an address listed
under the ADDRESSES section of this AD. Include ``Docket No. FAA-2009-
1003; Directorate Identifier 2009-SW-25-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of this AD. We will
consider all comments received by the closing date and may amend this
AD because of those comments.
We will post all comments we receive, without change, to https://www.regulations.gov including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.
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 product(s) 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.
Therefore, I certify this AD:
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
[[Page 56106]]
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 AD and placed it in the AD docket.

------------------------------------------------------------------------
Model Serial Nos.
------------------------------------------------------------------------
407.............................. 53000 through 53887, 53890 through
53916, 53918, 53920, 53921, 53923
through 53926, and 53928.
427.............................. 56001 through 56074.
------------------------------------------------------------------------
Reason
(d) The mandatory continuing airworthiness information (MCAI) AD
states during a preflight check it was observed that the swashplate
link assembly bearing had moved in the lever race, making contact
with the swashplate support. The MCAI AD also states that further
investigation revealed that the bearing had not been staked
correctly during manufacture. That condition, if not detected, could
result in failure of a bearing, failure of the link assembly, and
subsequent loss of control of the helicopter.
Actions and Compliance
(e) Required as indicated, unless accomplished previously.
(1) Within 10 hours time-in-service (TIS), using a 10x or higher
magnifying glass, inspect the link assembly and determine if the
bearing, P/N 406-310-403-101, is correctly installed and properly
staked in the link assembly. Also inspect to ensure that the bearing
is not loose.
(2) Before further flight, replace any bearing that is
incorrectly installed or improperly staked in the link assembly.
(3) Before further flight, replace the link assembly if the
bearing is loose.
Differences Between This AD and the MCAI AD
(f) This AD differs from the MCAI AD as follows:
(1) This AD requires compliance within 10 hours TIS, the MCAI AD
requires compliance within the next 10 flight hours, but no later
than 30 days from the effective day of the MCAI AD, which was May 6,
2009; and
(2) This AD does not apply to Model 427 helicopters, S/N 58001
or 58002, because those serial-numbered helicopters are not eligible
for an FAA certificate of airworthiness.
