Airworthiness Directives; BAE SYSTEMS (Operations) Limited Model
Avro 146-RJ and BAe 146 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated 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:
A potential fleet wide problem has been identified regarding the
interchanging of wing links on all BAe 146 & AVRO 146-RJ aircraft
during scheduled maintenance. Some
[[Page 12159]]
operators erroneously believed that these parts were
interchangeable. The effects of changing winglinks has resulted in
either a shorter or longer wing link being fitted, which introduces
local stresses in the wing top and bottom surfaces local to rib 2,
wing links and wing link fitting attachment and the fuselage local
to Frames 26 and 29. This condition, if not corrected, could result
in a reduction of structural integrity of the fuselage/wing
attachment with possible catastrophic consequences.
The unsafe condition could result in loss of a wing or
controllability of the airplane. The proposed AD would require actions
that are intended to address the unsafe condition described in the
MCAI.

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 2008-0003, dated January 8, 2008 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
A potential fleet wide problem has been identified regarding the
interchanging of wing links on all BAe 146 & AVRO 146-RJ aircraft
during scheduled maintenance. Some operators erroneously believed
that these parts were interchangeable. The effects of changing
winglinks has resulted in either a shorter or longer wing link being
fitted, which introduces local stresses in the wing top and bottom
surfaces local to rib 2, wing links and wing link fitting attachment
and the fuselage local to Frames 26 and 29. This condition, if not
corrected, could result in a reduction of structural integrity of
the fuselage/wing attachment with possible catastrophic
consequences.
For the reasons described above, the present Airworthiness
Directive (AD) requires the accomplishment of inspections and
rectification actions, as necessary.
The unsafe condition could result in loss of a wing or
controllability of the airplane. The inspections include inspecting
wing links for incorrect part numbers (i.e., parts that are not
original), inspecting to determine wing geometry measurements, and
inspecting the wing link, bores, bolts, and nuts for corrosion.
Corrective actions include installing wing-to-fuselage fairings and
repairing. 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.53-175, Revision 1, dated April 2, 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 180 work-hours per product to comply with the basic
requirements of
[[Page 12160]]
this proposed AD. The average labor rate is $85 per work-hour. Required
parts would cost about $0 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 the U.S. operator to be $15,300.
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.

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: Docket No. FAA-2010-0222;
Directorate Identifier 2008-NM-012-AD.
Comments Due Date
(a) We must receive comments by April 29, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to BAE Systems (Operations) Limited Model
BAe 146-100A, -200A, and -300A; and Avro 146-RJ70A, 146-RJ85A, and
146-RJ100A airplanes; all serial numbers; certificated in any
category; as identified in paragraph 1.A.(1) of BAE (Operations)
Limited Inspection Service Bulletin ISB.53-175, Revision 1, dated
April 2, 2007.
Subject
(d) Air Transport Association (ATA) of America Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
``A potential fleet wide problem has been identified regarding
the interchanging of wing links on all BAe 146 & AVRO 146-RJ
aircraft during scheduled maintenance. Some operators erroneously
believed that these parts were interchangeable. The effects of
changing winglinks has resulted in either a shorter or longer wing
link being fitted, which introduces local stresses in the wing top
and bottom surfaces local to rib 2, wing links and wing link fitting
attachment and the fuselage local to Frames 26 and 29. This
condition, if not corrected, could result in a reduction of
structural integrity of the fuselage/wing attachment with possible
catastrophic consequences.
``For the reasons described above, the present Airworthiness
Directive (AD) requires the accomplishment of inspections and
rectification actions, as necessary.''
The unsafe condition could result in loss of a wing or
controllability of the airplane. The inspections include inspecting
wing links for incorrect part numbers (i.e., parts that are not
original), inspecting to determine wing geometry measurements, and
inspecting the wing link, bores, bolts, and nuts for corrosion.
Corrective actions include installing wing-to-fuselage fairings and
repairing.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Actions
(g) Do the following actions.
(1) For airplanes subject to Maintenance Review Board Report
(MRBR) requirements: Within 30 days after the effective date of this
AD, revise the supplemental structural inspection (SSI) portion of
the airplane inspection schedule, in accordance with paragraph
1.D.(2) of BAE SYSTEMS (Operations) Limited Inspection Service
Bulletin ISB.53-175, Revision 1, dated April 2, 2007. Do the initial
inspection at the applicable time, and repeat at the applicable
intervals, as specified in Appendix 3 of BAE SYSTEMS (Operations)
Limited Inspection Service Bulletin ISB.53-175, Revision 1, dated
April 2, 2007. Where Appendix 3 of BAE SYSTEMS (Operations) Limited
Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2,
2007, does not specify a compliance time in either flight cycles or
in flight hours, use flight cycles.
(2) For airplanes subject to MRBR requirements: Accomplishing
the inspections and all applicable corrective actions of paragraph
1.D.(3) of BAE SYSTEMS (Operations) Limited Inspection Service
Bulletin ISB.53-175, Revision 1, dated April 2, 2007, terminates the
revisions to the SSI portion of the airplane inspection schedule
incorporated in accordance with paragraph (g)(1) of this AD,
provided that if any corrosion is found during any inspection
specified in ``Part C'' or ``Part D'' of paragraph 2.C. of BAE
SYSTEMS (Operations) Limited Inspection Service Bulletin ISB.53-175,
Revision 1, dated April 2, 2007, repair is accomplished before
further flight using a method approved by the Manager, International
Branch, ANM 116, Transport Airplane Directorate, FAA, or EASA (or
its delegated agent).
(3) For operational airplanes subject to MRBR-to-Supplemental-
Structural-Inspection-Document (SSID) transition requirements or to
SSID requirements: Within 5,000 flight cycles after the effective
date of this AD, do the inspections and all applicable corrective
actions, in accordance with paragraph 2.C. of the Accomplishment
Instructions of BAE SYSTEMS (Operations) Limited Inspection Service
Bulletin ISB.53-175, Revision 1, dated April 2, 2007, except if any
corrosion is found during any inspection specified in ``Part C'' or
``Part D'' of paragraph 2.C. of BAE SYSTEMS (Operations) Limited
Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2,
2007, repair must be accomplished using a method approved by the
Manager, International Branch, ANM 116, Transport Airplane
Directorate, FAA, or EASA (or its delegated agent). Do all
applicable corrective
[[Page 12161]]
actions before further flight, except that replacements of all the
wing links that are not within the specified tolerance must be done
before the airplane reaches its MRBR airframe life limit.
Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
(4) For any inspection done in accordance with paragraph (g)(2)
or (g)(3) of this AD: Send reports to BAE SYSTEMS, Customer Liaison,
Customer Support (Building 37), BAE SYSTEMS (Operations) Limited,
Prestwick International Airport, Ayrshire, KA9 2RW, Scotland, Fax
+44 (0) 1292 675432, e-mail [email protected], at the
applicable time in paragraph (g)(4)(i) or (g)(4)(ii) of this AD. The
report must include the inspection results, a description of any
discrepancies found, the airplane serial number, and the number of
landings and flight hours on the airplane.
(i) If the inspection was done on or after the effective date of
this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was done before the effective date of
this AD: Submit the report within 30 days after the effective date
of this AD.
(5) For airplanes that are non-operational as of the effective
date of this AD and that are subject to MRBR-to-SSID transition
requirements or to SSID requirements: Before returning any airplane
to service, do the inspections and all applicable corrective
actions, in accordance with paragraph 2.C. of the Accomplishment
Instructions of BAE SYSTEMS (Operations) Limited Inspection Service
Bulletin ISB.53-175, Revision 1, dated April 2, 2007, except if any
corrosion is found during any inspection specified in ``Part C'' or
``Part D'' of paragraph 2.C. of BAE SYSTEMS (Operations) Limited
Inspection Service Bulletin ISB.53-175, Revision 1, dated April 2,
2007, repair must be accomplished using a method approved by the
Manager, International Branch, ANM 116, Transport Airplane
Directorate, FAA, or EASA (or its delegated agent).
(6) Actions accomplished before the effective date of this AD in
accordance with BAE SYSTEMS (Operations) Limited Inspection Service
Bulletin ISB.53-175, dated December 21, 2006, are considered
acceptable for compliance with the corresponding action specified in
this AD.
FAA AD Differences
Note 2: This AD differs from the MCAI and/or service information
as follows: The MCAI does not specify a corrective action if
corrosion is found during accomplishment of the actions specified in
``Part C'' and ``Part D'' of paragraph 2.C. of BAE SYSTEMS
(Operations) Limited Inspection Service Bulletin ISB.53-175,
Revision 1, dated April 2, 2007. This AD requires that if any
corrosion is found, a repair must be done in accordance with a
method approved by the FAA or EASA (or its delegated agent).
Other FAA AD Provisions
(h) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
International Branch, ANM-116, FAA, has the authority to approve
AMOCs for this AD, if requested using the procedures found in 14 CFR
39.19. Send information to ATTN: Todd Thompson, Aerospace Engineer,
International Branch, ANM-116, Transport Airplane Directorate, FAA,
1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone
(425) 227-1175; fax (425) 227-1149. Before using any approved AMOC
on any airplane to which the AMOC applies, notify your principal
maintenance inspector (PMI) or principal avionics inspector (PAI),
as appropriate, or lacking a principal inspector, your local Flight
Standards District Office. The AMOC approval letter must
specifically reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
