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 February 7, 2011 (76 FR

Bombardier Aerospace has completed a
system safety review of the aeroplanes fuel
system against fuel tank safety standards
introduced in chapter 525 of the
Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002–043
[which corresponds with the FAA’s Special
Federal Aviation Regulation (SFAR) 88]. The
identified non-compliances were then
assessed using Transport Canada Policy
Letter No. 525–001, to determine if
mandatory corrective action is required.
The assessment showed that a number of
modifications to the fuel system are required
to mitigate unsafe conditions that could
result in potential ignition source within the
fuel system.
The Bombardier modifications include:
• Modsum 4–126330, ‘‘Fuel Tank
System Design Left and Right Side
(SFAR 88) Retrofit.’’ The retrofit
includes replacing certain fittings,
couplings, o-rings, gaskets, fuel adapter,
PO 00000
Frm 00018

Sfmt 4700
and other related components with new,
improved parts; applying Alodine 1132
to certain areas of a wing rib and a wing
spar; and replacing a certain doubler on
the front wing spar with a new,
improved doubler.
• Modsum 4–126366, ‘‘Fuel Tank
System and Fuel Indication—Wiring
Identification, Segregation and
Installation (High Level Sensor and Fuel
Quantity Indication)—Retrofit.’’ The
retrofit includes adding new wiring
with protective sleeving, reworking
existing wiring, labeling and separating
the fuel quantity indicating (FQI) wiring
and high level sensor wiring from other
wiring, enhancing the electro-magnetic
interference (EMI) shielding of the
wiring connected to the vent valve
position switch, and installing
additional provisions (bulkhead
brackets) for wiring clips in the center
fuselage.
• Modsum 4–901425, ‘‘Fuel Feed to
APU—Replacement of Couplings in
Center Wing Left Side—SFAR 88.’’
• Modsum 4–126370, ‘‘Fuel Tank
System—Enhance Protective Covering
for Electrical Cable Assembly,’’ which
includes reworking the contact area on
the rib at Yw–42.000 to ensure adequate
electrical bonding, installing spiral wrap
on certain cable assemblies where
existing spiral wrap does not extend 4
inches past the tie mounts, applying a
dome seal on thread openings on a high
level sensor, and installing fuel
grommets at certain locations.
• Modsum 4–113580, ‘‘Fuel
Indication—High Level Sensor—
Application of Sealant to Exposed End
of Sensor Terminal Block Screws—
Special Inspection and Rectification,’’
which includes doing a detailed
inspection of the high level sensor for
correct sealant coverage (‘dome seal’) on
the terminal screws, and applying
sealant 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
E:\FR\FM\27JNR1.SGM
27JNR1
Federal Register / Vol. 76, No. 123 / Monday, June 27, 2011 / Rules and Regulations
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
67 products of U.S. registry. We also
estimate that it will take about 526
work-hours per product to comply with
the basic requirements of this AD. The
average labor rate is $85 per work-hour.
Required parts will cost about $37,696
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
$5,521,202, or $82,406 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
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
VerDate Mar<15>2010

Jkt 223001
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) 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.
Examining the AD Docket
You may examine the AD docket on
the Internet at
https://www.regulations.gov; or in person

SUPPLEMENTARY INFORMATION:
DATES:
History
Establishment of Helicopter Area
Navigation (RNAV) Routes; Northeast
United States
SUMMARY:
Date
On Tuesday, March 8, 2011, the FAA
published in the Federal Register a
notice of proposed rulemaking to
establish two helicopter RNAV routes in
Northeast United States (76 FR 12643).
Interested parties were invited to
participate in this rulemaking effort by
submitting written comments on the
proposal. Four people submitted
comments on the proposal.
Discussion of Comments
Two commenters wrote expressing
support for the proposal. Two
commenters raised several issues which
are discussed below. One commenter
questioned the need for a new type of
airway for helicopters stating that the
existing system of VOR Federal airways
and RNAV T-routes should be
sufficient. The commenter wrote, in the
past, the FAA had designated routes for
helicopters in the northeast, but they
were seldom available for use.
PO 00000
Frm 00021
Fmt 4700
Sfmt 4700
Additionally, the commenter asked if
the air traffic control separation
standards for IFR helicopters differ from
those that apply to fixed-wing aircraft;
contending that, if they are the same,
there is no need for helicopter airways.
The past routes noted by the
commenter were initiated in FAA
Advisory Circular AC 73–2, ‘‘IFR
Helicopter Operations in the Northeast
Corridor,’’ dated June 11, 1979. AC 73–
2 advised of special RNAV helicopter
routes between Washington, DC, and
Boston, MA. The routes were developed
consistent with conventional traffic
flows for use by helicopters under IFR
conditions. Use of these routes was
limited only to those operators that met
specified criteria and were issued a
letter of authorization from the FAA.
Therefore, the routes were not available
for general use and they were not
depicted on IFR Enroute Low Altitude
charts. The Advisory Circular was
subsequently cancelled because the
routes were designed for first generation
RNAV systems which lacked the
accuracy and reliability of satellite
navigation and other advanced RNAV
systems. Additionally, it was
determined that the routes do not meet
current Air Traffic Service route criteria.
On March 26, 2007, the FAA issued a
Letter to Airmen containing new
routings to be filed with a ‘‘fix-to-fix’’
flight plan along the ‘‘old’’ IFR northeast
corridor. As with the Advisory Circular
routes, these routes are not depicted on
IFR En route Low Altitude charts. The
new TK routes in this rule approximate
the former northeast corridor route

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This 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:
Bombardier Aerospace has completed a system safety review of the
aeroplanes fuel system against fuel tank safety standards introduced
in Chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043 [which corresponds with the FAA's
Special Federal Aviation Regulation (SFAR) 88]. The identified non-
compliances were then assessed using Transport Canada Policy Letter
No. 525-001, to determine if mandatory corrective action is
required.
The assessment showed that a number of modifications to the fuel
system are required to mitigate unsafe conditions that could result
in potential ignition source within the fuel system.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective August 1, 2011.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of August 1,
2011.

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 February 7, 2011 (76
FR 6584). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
Bombardier Aerospace has completed a system safety review of the
aeroplanes fuel system against fuel tank safety standards introduced
in chapter 525 of the Airworthiness Manual through Notice of
Proposed Amendment (NPA) 2002-043 [which corresponds with the FAA's
Special Federal Aviation Regulation (SFAR) 88]. The identified non-
compliances were then assessed using Transport Canada Policy Letter
No. 525-001, to determine if mandatory corrective action is
required.
The assessment showed that a number of modifications to the fuel
system are required to mitigate unsafe conditions that could result
in potential ignition source within the fuel system.
The Bombardier modifications include:
Modsum 4-126330, ``Fuel Tank System Design Left and Right
Side (SFAR 88) Retrofit.'' The retrofit includes replacing certain
fittings, couplings, o-rings, gaskets, fuel adapter, and other related
components with new, improved parts; applying Alodine 1132 to certain
areas of a wing rib and a wing spar; and replacing a certain doubler on
the front wing spar with a new, improved doubler.
Modsum 4-126366, ``Fuel Tank System and Fuel Indication--
Wiring Identification, Segregation and Installation (High Level Sensor
and Fuel Quantity Indication)--Retrofit.'' The retrofit includes adding
new wiring with protective sleeving, reworking existing wiring,
labeling and separating the fuel quantity indicating (FQI) wiring and
high level sensor wiring from other wiring, enhancing the electro-
magnetic interference (EMI) shielding of the wiring connected to the
vent valve position switch, and installing additional provisions
(bulkhead brackets) for wiring clips in the center fuselage.
Modsum 4-901425, ``Fuel Feed to APU--Replacement of
Couplings in Center Wing Left Side--SFAR 88.''
Modsum 4-126370, ``Fuel Tank System--Enhance Protective
Covering for Electrical Cable Assembly,'' which includes reworking the
contact area on the rib at Yw-42.000 to ensure adequate electrical
bonding, installing spiral wrap on certain cable assemblies where
existing spiral wrap does not extend 4 inches past the tie mounts,
applying a dome seal on thread openings on a high level sensor, and
installing fuel grommets at certain locations.
Modsum 4-113580, ``Fuel Indication--High Level Sensor--
Application of Sealant to Exposed End of Sensor Terminal Block Screws--
Special Inspection and Rectification,'' which includes doing a detailed
inspection of the high level sensor for correct sealant coverage (`dome
seal') on the terminal screws, and applying sealant 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
[[Page 37259]]
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 67 products of U.S. registry.
We also estimate that it will take about 526 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $37,696 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 $5,521,202, or $82,406 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
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 that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
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.
