consecutive restart of the avionics. During
initial investigation, a loose connection on
the DC load distribution system was
discovered and determined to be the root
cause of this event. However, further analysis
pointed out that large electrical transients on
the essential bus bar may possibly cause
simultaneous and temporary power shortage
on both sides of the electrical system.
This Airworthiness Directive (AD) requires
a wiring modification of the GCUs (Generator
Control Units) to increase the electrical
system robustness. This action is necessary to
prevent a momentary loss of data on the EFIS
screens, which could lead to the pilot’s loss
of situational awareness during initial climb
or approach/landing, and possibly result in
reduced control of the airplane. This action
is intended to address the identified unsafe
condition.

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 May 13, 2008 (73 FR 27477).
That NPRM proposed to correct an
unsafe condition for the specified
products. The MCAI states:
Resulting from the assessment of fuel tank
wiring installations required by SFAR 88
(Special Federal Aviation Regulation 88) and
equivalent JAA/EASA (Joint Aviation
Authorities/European Aviation Safety
Agency) policy, BAE Systems identified two
features in the Jetstream 4100 where the need
for design changes was apparent. One of
these is addressed by Service Bulletin (SB)
J41–28–013 which introduces additional
bonding leads between pipes, structure and
various components to improve the electrical
bond paths within the fuel tank areas. This
design change is identified by modification
number JM41659. Additionally, SB J41–28–
013 provides instructions to inspect the
existing bonding leads, to replace any
defective leads and to examine all fuel
system pipe runs in the wings to ensure
appropriate clearances are maintained.
Insufficient or defective bonding in the fuel
tank area, if not corrected, could lead to
ignition of fuel vapours and subsequent fuel
tank explosion.
For the reason stated above, this EASA
Airworthiness Directive (AD) requires the
VerDate Aug<31>2005

Jkt 214001
installation of additional bonding leads,
inspection [for defects] of existing bonding
leads and [for clearance of] all fuel system
pipe runs in the wings and follow-on
corrective actions, as necessary.
Corrective actions include replacing any
defective bonding leads and adjusting
clearances of the fuel system pipe runs.
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 7 products of U.S. registry. We
also estimate that it will take about 80
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 $1,700
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
$56,700, or $8,100 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:
PO 00000
Frm 00005
Fmt 4700
Sfmt 4700
45347
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

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 May 13, 2008 (73 FR
27477). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Resulting from the assessment of fuel tank wiring installations
required by SFAR 88 (Special Federal Aviation Regulation 88) and
equivalent JAA/EASA (Joint Aviation Authorities/European Aviation
Safety Agency) policy, BAE Systems identified two features in the
Jetstream 4100 where the need for design changes was apparent. One
of these is addressed by Service Bulletin (SB) J41-28-013 which
introduces additional bonding leads between pipes, structure and
various components to improve the electrical bond paths within the
fuel tank areas. This design change is identified by modification
number JM41659. Additionally, SB J41-28-013 provides instructions to
inspect the existing bonding leads, to replace any defective leads
and to examine all fuel system pipe runs in the wings to ensure
appropriate clearances are maintained.
Insufficient or defective bonding in the fuel tank area, if not
corrected, could lead to ignition of fuel vapours and subsequent
fuel tank explosion.
For the reason stated above, this EASA Airworthiness Directive
(AD) requires the installation of additional bonding leads,
inspection [for defects] of existing bonding leads and [for
clearance of] all fuel system pipe runs in the wings and follow-on
corrective actions, as necessary.
Corrective actions include replacing any defective bonding leads and
adjusting clearances of the fuel system pipe runs. 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 7 products of U.S.
registry. We also estimate that it will take about 80 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 $1,700
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 $56,700, or $8,100 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

Accordingly, under the authority delegated to me by the Administrator,
[[Page 45348]]
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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:
2008-16-06 BAE Systems (Operations) Limited (Formerly British
Aerospace Regional Aircraft): Amendment 39-15624. Docket No. FAA-
2008-0541; Directorate Identifier 2008-NM-063-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective
September 9, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all BAE Systems (Operations) Limited
Model Jetstream 4101 airplanes, certificated in any category, all
serial numbers.
Subject
(d) Air Transport Association (ATA) of America Code 28: Fuel.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Resulting from the assessment of fuel tank wiring installations
required by SFAR 88 (Special Federal Aviation Regulation 88) and
equivalent JAA/EASA (Joint Aviation Authorities/European Aviation
Safety Agency) policy, BAE Systems identified two features in the
Jetstream 4100 where the need for design changes was apparent. One
of these is addressed by Service Bulletin (SB) J41-28-013 which
introduces additional bonding leads between pipes, structure and
various components to improve the electrical bond paths within the
fuel tank areas. This design change is identified by modification
number JM41659. Additionally, SB J41-28-013 provides instructions to
inspect the existing bonding leads, to replace any defective leads
and to examine all fuel system pipe runs in the wings to ensure
appropriate clearances are maintained.
Insufficient or defective bonding in the fuel tank area, if not
corrected, could lead to ignition of fuel vapours and subsequent
fuel tank explosion.
For the reason stated above, this EASA Airworthiness Directive
(AD) requires the installation of additional bonding leads,
inspection [for defects] of existing bonding leads and [for
clearance of] all fuel system pipe runs in the wings and follow-on
corrective actions, as necessary.
Corrective actions include replacing any defective bonding leads and
adjusting clearances of the fuel system pipe runs.
Actions and Compliance
(f) Within 24 months after the effective date of this AD, unless
already done, do the following actions.
(1) Inspect the bonding leads between ribs 1 and 9, and between
ribs 16 and 19, in the left-hand (LH) and right-hand (RH) wings in
accordance with paragraph 2.B.(2) of the Accomplishment Instructions
of BAE Systems (Operations) Limited Service Bulletin J41-28-013,
Revision 1, dated January 10, 2008; and, before next flight, replace
all defective bonding leads with airworthy parts in accordance with
the service bulletin.
(2) Inspect all fuel system pipe runs inside the LH and RH wings
in accordance with paragraph 2.B.(3) of the Accomplishment
Instructions of BAE Systems (Operations) Limited Service Bulletin
J41-28-013, Revision 1, dated January 10, 2008; and, if incorrect
clearances are found, before next flight, adjust clearances in
accordance with the service bulletin.
(3) Install additional electrical bonding of components within
the LH and RH wings in accordance with paragraphs 2.B.(4) to
2.B.(15) of the Accomplishment Instructions of BAE Systems
(Operations) Limited Service Bulletin J41-28-013, Revision 1, dated
January 10, 2008.
