Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued EASA
Airworthiness Directive 2007–0277,
dated November 5, 2007 (referred to
after this as ‘‘the MCAI’’), 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.
E:\FR\FM\21AUP1.SGM
21AUP1
Federal Register / Vol. 73, No. 163 / Thursday, August 21, 2008 / Proposed Rules
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
repair instructions and repair, if
necessary. You may obtain further
information by examining the MCAI in
the AD docket.
Relevant Service Information
BAE Systems (Operations) Limited
has issued Inspection Service Bulletin
ISB.53–194, dated January 10, 2007. 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.

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 proposed
different actions in this AD from those
in the MCAI in order to follow FAA
policies. Any such differences are
highlighted in a NOTE within the
proposed AD.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 1 product of U.S. registry.
We also estimate that it would take
about 24 work-hours per product to
comply with the basic requirements of
VerDate Aug<31>2005
17:27 Aug 20, 2008
Jkt 214001
this proposed AD. The average labor
rate is $80 per work-hour. Required
parts would 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 costs. 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 the
proposed AD on 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 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 a regulatory evaluation
of the estimated costs to comply with
this proposed AD and placed it in the
AD docket.

AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing Model 767–200 and 767–
300 series airplanes. This proposed AD
would require detailed inspections of
the aft pressure bulkhead for damage,
mid-frequency eddy current (MFEC) and
low frequency eddy current (LFEC)
inspections of radial web lap splices,
tear strap splices, and super tear strap
splices for cracking, and corrective
actions if necessary. This AD results
from analysis that indicates fatigue
cracks of the web lap splice, tear strap
splice, or super tear strap splice of the
aft bulkhead are expected to occur on
certain Boeing Model 767–200 and 767–
300 series airplanes. We are proposing
this AD to detect and correct fatigue
cracks of the aft pressure bulkhead,
which could result in rapid
decompression of the passenger
compartment and possible damage or
interference with airplane control
systems that penetrate the bulkhead,
and consequent loss of controllability of
the airplane.
DATES: We must receive comments on
this proposed AD by October 6, 2008.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2007-0277, dated November 5, 2007 (referred to
after this as ``the MCAI''), 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.
[[Page 49365]]
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. You may obtain
further information by examining the MCAI in the AD docket.
Relevant Service Information
BAE Systems (Operations) Limited has issued Inspection Service
Bulletin ISB.53-194, dated January 10, 2007. 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.
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 proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 1 product of U.S. registry. We also estimate that it
would take about 24 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would 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
costs. 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 the proposed AD on 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 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 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
Air transportation, Aircraft, Aviation safety, Safety.
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:
BAE Systems (Operations) Limited (Formerly British Aerospace
Regional Aircraft): Docket No. FAA-2008-0887; Directorate Identifier
2007-NM-336-AD.
Comments Due Date
(a) We must receive comments by September 22, 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
[[Page 49366]]
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 paragraph (f)(3)
and (f)(4) of this AD.
(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.
