inspections of the hydraulic tube required by
paragraphs (f)(1)(i) and (f)(1)(v) of this AD.
FAA AD Differences
Note 1: This AD differs from the MCAI
and/or service information as follows:
(1) The MCAI does not specify service
information if any tube replacement is done.
This AD requires doing the replacement as
specified in paragraph (f)(1)(iii) of this AD.
(2) The MCAI specifies doing a one-time
inspection of the installed Teflon blocks but
also specifies doing repetitive inspections of
temporary replacement Teflon blocks until
the permanent replacement with Nylon 6/6
clamping blocks is done. This AD requires
repetitive inspections of all Teflon blocks
until the permanent replacement is done.
(3) The MCAI specifies that doing the
replacement with Nylon 6/6 clamping blocks
constitutes terminating action. This AD
specifies that doing the replacement with
Nylon 6/6 clamping blocks constitutes
terminating action for the inspections of the
clamping blocks and for the repetitive
inspections of the hydraulic tubes.

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 August 21, 2008 (73 FR
49364). That NPRM proposed to correct
an unsafe condition for the specified
products. The MCAI states:
During inspection of undercarriage main
beam sidestays, bolts attaching the
undercarriage main beam sidestay to frame
29 were found with the heads of the bolts
sheared off. Loose bolt assemblies were also
found.
If sheared or loose bolts are not detected
and replaced, a possible consequence is the
collapse of the main landing gear.
For the reasons described above, this
Airworthiness Directive (AD) requires a onetime [rotating eddy current] inspection of the
bolt bores and bore dimensions and the
installation of replacement bolts, as
necessary.
Corrective actions include contacting
BAE Systems (Operations) Limited for
E:\FR\FM\20NOR1.SGM
20NOR1
70266
Federal Register / Vol. 73, No. 225 / Thursday, November 20, 2008 / Rules and Regulations
repair instructions and repair, if
necessary. You may obtain further
information by examining the MCAI in
the AD docket.
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 our FAA
policies. Any such differences are
highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect
about 1 product of U.S. registry. We also
estimate that it will take about 24 workhours per product to comply with the
basic requirements of this AD. The
average labor rate is $80 per work-hour.
Required parts will cost about $1,000
per product. Where the service
information lists required parts costs
that are covered under warranty, we
have assumed that there will be no
charge for these parts. As we do not
control warranty coverage for affected
parties, some parties may incur costs
higher than estimated here. Based on
these figures, we estimate the cost of
this AD to the U.S. operators to be
$2,920, or $2,920 per product.
rwilkins on PROD1PC63 with RULES
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:
VerDate Aug<31>2005
18:21 Nov 19, 2008
Jkt 217001
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 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 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 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 Operations office 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 street address for
the Docket Operations office (telephone
(800) 647–5527) is in the ADDRESSES
section. Comments will be available in
the AD docket shortly after receipt.

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 our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect about 1 product of U.S.
registry. We also estimate that it will take about 24 work-hours per
product to comply with the basic requirements of this AD. The average
labor rate is $80 per work-hour. Required parts will cost about $1,000
per product. Where the service information lists required parts costs
that are covered under warranty, we have assumed that there will be no
charge for these parts. As we do not control warranty coverage for
affected parties, some parties may incur costs higher than estimated
here. Based on these figures, we estimate the cost of this AD to the
U.S. operators to be $2,920, or $2,920 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 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 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 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 Operations office
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 street address for
the Docket Operations office (telephone (800) 647-5527) is in the
ADDRESSES section. Comments will be available in the AD docket shortly
after receipt.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 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]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2008-23-14 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-15735. Docket No. FAA-
2008-0887; Directorate Identifier 2007-NM-336-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
26, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all BAE Systems (Operations) Limited
Model BAe 146-100A, -200A, and -300A series airplanes; and Model
Avro 146-RJ70A, 146-RJ85A, and 146-RJ100A airplanes; certificated in
any category.
Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
During inspection of undercarriage main beam sidestays, bolts
attaching the undercarriage main beam sidestay to frame 29 were
found with the heads of the bolts sheared off. Loose bolt assemblies
were also found.
If sheared or loose bolts are not detected and replaced, a
possible consequence is the collapse of the main landing gear.
For the reasons described above, this Airworthiness Directive
(AD) requires a one-time [rotating eddy current] inspection of the
bolt bores and bore dimensions and the installation of replacement
bolts, as necessary.
Corrective actions include contacting BAE Systems (Operations)
Limited for repair instructions and repair, if necessary.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 4,000 flight cycles or 5 years, whichever occurs
first after the effective date of this AD, perform the inspections
to detect defects (including sheared or loose bolts) and do the bolt
replacements in accordance with the instructions of paragraphs
2.C.(1) through 2.C.(3), and paragraphs 2.D.(1) through 2.D.(3), of
the Accomplishment Instructions of BAE Systems (Operations) Limited
Inspection Service Bulletin ISB.53-194, dated January 10, 2007,
except as required by paragraphs (f)(2), (f)(3), and (f)(4) of this
AD.
(2) If any defect is found during the inspection specified in
paragraph (f)(1) of this AD, before further flight, replace the
affected bolts in accordance with the Accomplishment Instructions of
BAE Systems (Operations) Limited Inspection Service Bulletin ISB.53-
194, dated January 10, 2007, except as required by paragraphs (f)(3)
and (f)(4) of this AD.
[[Page 70267]]
(3) For airplanes on which replacement parts are not available
during the replacement specified in paragraph (f)(2) of this AD, do
the actions in paragraphs (f)(3)(i) and (f)(3)(ii) of this AD in
accordance with the Accomplishment Instructions of BAE Systems
(Operations) Limited Inspection Service Bulletin ISB.53-194, dated
January 10, 2007.
(i) Before further flight, temporarily reinstall removed
oversized bolts, provided the bolts are serviceable.
(ii) Within 2,000 flight cycles after doing the inspection
required by paragraph (f)(1) of this AD, replace all temporary
oversized bolts that were installed in accordance with paragraph
(f)(3)(i) of this AD.
(4) Where BAE Systems (Operations) Limited Inspection Service
Bulletin ISB.53-194, dated January 10, 2007, specifies to contact
BAE Systems (Operations) Limited if any defect is found in the
second oversize fastener bore, before further flight, contact BAE
Systems (Operations) Limited for repair instructions and do the
repair.
