ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
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:
In-service reports have been received by
BAE of failed bolts fitted to frame 199 wing
spigot post assembly. If left uncorrected
failure of these bolts will severely
compromise the structural integrity of the
wing to fuselage attachment. Failure of which
would lead to loss of the aircraft. To address
these concerns, BAE issued SB 57–JA020740
original issue in February 2003 mandated by
CAA AD 006–02–2003. Recently received
additional information has caused BAE to
raise the Service Bulletin to revision 2.
Revision 2 of the SB introduces various
changes. One is substantive, it relates to the
need to check for correct washer installation.
Incorrect installation could lead to fretting
and fatigue crack initiation in the fitting
followed by failure or bending loads in the
bolt leading to failure of the affected bolts. If
left uncorrected failure of these bolts or a

wing fitting will severely compromise the
structural integrity of the wing to fuselage
attachment, failure of which would lead to
loss of the aircraft. This substantive change
to the service bulletin necessitates the raising
of this superseding AD.
The proposed AD would require actions
that are intended to address the unsafe
condition described in the MCAI.
DATES: We must receive comments on
this proposed AD by June 18, 2007.
ADDRESSES: You may send comments by
any of the following methods:

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. This streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to
follow all FAA AD issuance processes to
meet legal, economic, Administrative
Procedure Act, and Federal Register
requirements. We also continue to meet
our technical decision-making
responsibilities to identify and correct

products.
This proposed AD references the
MCAI and related service information
that we considered in forming the
engineering basis to correct the unsafe
condition. The proposed AD contains
text copied from the MCAI and for this
reason might not follow our plain
language principles.

Discussion
The European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued AD No: G–
2006–0003, dated February 2, 2006
(referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products.
The MCAI states:
In-service reports have been received by
BAE of failed bolts fitted to frame 199 wing
spigot post assembly. If left uncorrected
failure of these bolts will severely
compromise the structural integrity of the
wing to fuselage attachment. Failure of which
would lead to loss of the aircraft. To address

You may obtain further information
by examining the MCAI in the AD
docket.
Relevant Service Information
British Aerospace Regional Aircraft
has issued British Aerospace Jetstream
Series 3100 and 3200 Service Bulletin
57–JA020740, Revision 2, dated
November 2, 2005. The actions
described in this service information are
intended to correct the unsafe condition
identified in the MCAI.
FAA’s Determination and Requirements
of the 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 this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
Differences Between This Proposed 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 195 products of U.S.
registry. We also estimate that it would
take about 50 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 $100 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.
PO 00000
Frm 00026
Fmt 4702
Sfmt 4702
Based on these figures, we estimate
the cost of the proposed AD on U.S.
operators to be $799,500, or $4,100 per
product.
Estimate above is based on Pre-Mod
7130 installed per airplane. We estimate
it would take about 25 work-hours per
product if Post-Mod 7130 is installed.
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.

cprice-sewell on PRODPC61 with PROPOSALS
Reason
(e) The mandatory continuing
airworthiness information (MCAI) states:
In-service reports have been received by
BAE of failed bolts fitted to frame 199 wing
spigot post assembly. If left uncorrected
failure of these bolts will severely
compromise the structural integrity of the
wing to fuselage attachment. Failure of which
would lead to loss of the aircraft. To address
these concerns, BAE issued SB 57–JA020740
original issue in February 2003 mandated by
CAA AD 006–02–2003. Recently received
additional information has caused BAE to
raise the Service Bulletin to revision 2.
Revision 2 of the SB introduces various
changes. One is substantive, it relates to the
need to check for correct washer installation.
Incorrect installation could lead to fretting
and fatigue crack initiation in the fitting
followed by failure or bending loads in the
bolt leading to failure of the affected bolts. If
left uncorrected failure of these bolts or a
wing fitting will severely compromise the
structural integrity of the wing to fuselage
attachment. Failure of which would lead to
loss of the aircraft. This substantive change
to the service bulletin necessitates the raising
of this superseding AD.
Actions and Compliance
(f) Unless already done, do the following
actions using British Aerospace Jetstream
Series 3100 and 3200 Service Bulletin 57–
JA020740, Revision 2, dated November 2,
2005.
(1) Initially, within 90 days or 100 hours
time-in-service (TIS), whichever occurs first,
after the effective date of this AD and
repetitively thereafter at intervals not to
VerDate Aug<31>2005
15:31 May 17, 2007
Jkt 211001
exceed 4,000 hours TIS, inspect and torque
check the bolts at frame 199.
(2) If any discrepancies are found in any
of the inspections required in paragraph (f)(1)
of this AD, before further flight, correct any
discrepancies.
Note: This AD differs from the MCAI and/
or service information as follows: We added
repetitive inspection requirements in this
proposed AD to coincide with the service
bulletin.
Other FAA AD Provisions
(g) The following provisions also apply to
this AD:
(1) Alternative Methods of Compliance
(AMOCs): The Manager, Standards Staff,
FAA, ATTN: Doug Rudolph, Aerospace
Engineer, FAA, Small Airplane Directorate,
901 Locust, Room 301, Kansas City, Missouri

329–4090, has the authority to approve
AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. Before
using any approved AMOC on any airplane
to which the AMOC applies, notify your
appropriate principal inspector (PI) in the
FAA Flight Standards District Office (FSDO),
or lacking a PI, your local FSDO.
(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.

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:
In-service reports have been received by BAE of failed bolts
fitted to frame 199 wing spigot post assembly. If left uncorrected
failure of these bolts will severely compromise the structural
integrity of the wing to fuselage attachment. Failure of which would
lead to loss of the aircraft. To address these concerns, BAE issued
SB 57-JA020740 original issue in February 2003 mandated by CAA AD
006-02-2003. Recently received additional information has caused BAE
to raise the Service Bulletin to revision 2. Revision 2 of the SB
introduces various changes. One is substantive, it relates to the
need to check for correct washer installation. Incorrect
installation could lead to fretting and fatigue crack initiation in
the fitting followed by failure or bending loads in the bolt leading
to failure of the affected bolts. If left uncorrected failure of
these bolts or a wing fitting will severely compromise the
structural integrity of the wing to fuselage attachment, failure of
which would lead to loss of the aircraft. This substantive change to
the service bulletin necessitates the raising of this superseding
AD.
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by June 18, 2007.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance
of ADs related to MCAI. This streamlined process will allow us to adopt
MCAI safety requirements in a more efficient manner and will reduce
safety risks to the public. This process continues to follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
[[Page 28006]]
unsafe conditions on U.S.-certificated products.
This proposed AD references the MCAI and related service
information that we considered in forming the engineering basis to
correct the unsafe condition. The proposed AD contains text copied from
the MCAI and for this reason might not follow our plain language
principles.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued AD
No: G-2006-0003, dated February 2, 2006 (referred to after this as
``the MCAI''), to correct an unsafe condition for the specified
products.
The MCAI states:
In-service reports have been received by BAE of failed bolts
fitted to frame 199 wing spigot post assembly. If left uncorrected
failure of these bolts will severely compromise the structural
integrity of the wing to fuselage attachment. Failure of which would
lead to loss of the aircraft. To address these concerns, BAE issued
SB 57-JA020740 original issue in February 2003 mandated by CAA AD
006-02-2003. Recently received additional information has caused BAE
to raise the Service Bulletin to revision 2. Revision 2 of the SB
introduces various changes. One is substantive, it relates to the
need to check for correct washer installation. Incorrect
installation could lead to fretting and fatigue crack initiation in
the fitting followed by failure or bending loads in the bolt leading
to failure of the affected bolts. If left uncorrected failure of
these bolts or a wing fitting will severely compromise the
structural integrity of the wing to fuselage attachment, failure of
which would lead to loss of the aircraft. This substantive change to
the service bulletin necessitates the raising of this superseding
AD.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
British Aerospace Regional Aircraft has issued British Aerospace
Jetstream Series 3100 and 3200 Service Bulletin 57-JA020740, Revision
2, dated November 2, 2005. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Differences Between This Proposed 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 195 products of U.S. registry. We also estimate that
it would take about 50 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 $100 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 $799,500, or $4,100 per product.
Estimate above is based on Pre-Mod 7130 installed per airplane. We
estimate it would take about 25 work-hours per product if Post-Mod 7130
is installed.
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,
[[Page 28007]]
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:
British Aerospace Regional Aircraft: Docket No. FAA-2007-27861;
Directorate Identifier 2007-CE-035-AD.
Comments Due Date
(a) We must receive comments by June 18, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Jetstream HP.137 Jetstream Mk.1,
Jetstream Series 200, Jetstream Series 3101, and Jetstream Model
3201 airplanes, all serial numbers, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 57: Wings.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
In-service reports have been received by BAE of failed bolts
fitted to frame 199 wing spigot post assembly. If left uncorrected
failure of these bolts will severely compromise the structural
integrity of the wing to fuselage attachment. Failure of which would
lead to loss of the aircraft. To address these concerns, BAE issued
SB 57-JA020740 original issue in February 2003 mandated by CAA AD
006-02-2003. Recently received additional information has caused BAE
to raise the Service Bulletin to revision 2. Revision 2 of the SB
introduces various changes. One is substantive, it relates to the
need to check for correct washer installation. Incorrect
installation could lead to fretting and fatigue crack initiation in
the fitting followed by failure or bending loads in the bolt leading
to failure of the affected bolts. If left uncorrected failure of
these bolts or a wing fitting will severely compromise the
structural integrity of the wing to fuselage attachment. Failure of
which would lead to loss of the aircraft. This substantive change to
the service bulletin necessitates the raising of this superseding
AD.
Actions and Compliance
(f) Unless already done, do the following actions using British
Aerospace Jetstream Series 3100 and 3200 Service Bulletin 57-
JA020740, Revision 2, dated November 2, 2005.
(1) Initially, within 90 days or 100 hours time-in-service
(TIS), whichever occurs first, after the effective date of this AD
and repetitively thereafter at intervals not to exceed 4,000 hours
TIS, inspect and torque check the bolts at frame 199.
(2) If any discrepancies are found in any of the inspections
required in paragraph (f)(1) of this AD, before further flight,
correct any discrepancies.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: We added repetitive inspection requirements in this
proposed AD to coincide with the service bulletin.
Other FAA AD Provisions
(g) The following provisions also apply to this AD:
