ACTION: Final rule.
AGENCY:
We are superseding
airworthiness directive (AD) 2012–14–
04 for certain Bombardier, Inc. Model
DHC–8–100, –200, and –300 series
airplanes. AD 2012–14–04 required
replacing certain parking brake
accumulators. This new AD retains this
requirement. This new AD also requires
installing restraint devices around the
parking brake accumulator end caps. We
are issuing this AD to prevent failure of
a parking brake accumulator screw cap
or end cap resulting in loss of the
number 2 hydraulic system and damage
to airplane structures, which could
adversely affect the controllability of the
airplane.

SUPPLEMENTARY INFORMATION:
tkelley on DSK3SPTVN1PROD with RULES
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2012–14–04,
which applies to the specified products.
The NPRM was published in the
Federal Register on March 26, 2013 (78
FR 18257), and proposed to correct an
unsafe condition for the specified
products. Transport Canada Civil
Aviation (TCCA), which is the aviation
authority for Canada, issued Canadian
Airworthiness Directive CF–2011–29R1,
dated May 24, 2012 (the Mandatory
Continuing Airworthiness Information,
referred to after this as ‘‘the MCAI’’), to
correct an unsafe condition for the
specified products. The MCAI states:
Seven cases of on-ground hydraulic
accumulator screw cap or end cap failure
have been experienced on CL–600–2B19
* * * aeroplanes, resulting in loss of the
associated hydraulic system and high-energy
impact damage to adjacent systems and
structure. To date, the lowest number of
flight cycles accumulated at the time of
failure has been 6991.
Although there have been no failures to
date on any DHC–8 aeroplanes, similar
accumulators to those installed on the CL–
600–2B19, Part Numbers (P/N)08–60162–001
and 08–60162–002 (Parking Brake
Accumulator), are installed on the aeroplanes
listed in the Applicability section of this
[TCCA] directive.
A detailed analysis of the systems and
structure in the potential line of trajectory of
a failed screw cap/end cap for the
accumulator has been conducted. It has
identified that the worst-case scenarios
would be the loss of number 2 hydraulic
system, and damage to aeroplane structures.
This [original TCCA] directive [which
corresponds to FAA AD 2012–14–04,
Amendment 39–17118 (77 FR 42956, July 23,
2012)] gives instructions to determine the
part number and serial number of the
existing parking brake accumulator, and
where applicable, replace the accumulator.
Revision 1 of this [TCCA] AD mandates the
installation of restraint devices around [all]
the parking brake accumulator end caps to
hold them in place in the event of an end cap
failure.
Uncontained failure of the parking brake
accumulator screw caps and/or end caps
VerDate Mar<15>2010
17:14 Aug 05, 2013
Jkt 229001
could result in loss of the number 2
hydraulic system, and damage to
airplane structures, and could adversely
affect the controllability of the airplane.
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 (78
FR 18257 March 26, 2013) 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 this AD
as proposed–except for minor editorial
changes. We have determined that these
minor changes:
• Are consistent with the intent that
was proposed in the NPRM (78 FR
18257 March 26, 2013) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (78 FR 18257
March 26, 2013).
Costs of Compliance
We estimate that this AD will affect
about 129 products of U.S. registry.
The actions that were required by AD
2012–14–04, Amendment 39–17118 (77
FR 42956, July 23, 2012), and retained
in this AD take about 2 work-hours per
product, at an average labor rate of $85
per work-hour. Based on these figures,
the estimated cost of the currently
required actions is $170 per product.
We estimate that it will take about 15
work-hours per product to comply with
the new basic requirements of this AD.
The average labor rate is $85 per workhour. Required parts will cost about
$5,302 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
$848,433, or $6,577 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,
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
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 that 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);
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.
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 this AD, the regulatory
evaluation, any comments received, and
other information. The street address for
the Docket Operations office (telephone

Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding airworthiness directive (AD) 2012-14-04 for
certain Bombardier, Inc. Model DHC-8-100, -200, and -300 series
airplanes. AD 2012-14-04 required replacing certain parking brake
accumulators. This new AD retains this requirement. This new AD also
requires installing restraint devices around the parking brake
accumulator end caps. We are issuing this AD to prevent failure of a
parking brake accumulator screw cap or end cap resulting in loss of the
number 2 hydraulic system and damage to airplane structures, which
could adversely affect the controllability of the airplane.
DATES: This AD becomes effective September 10, 2013.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of September
10, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain other publications listed in this AD as of August
27, 2012 (77 FR 42956, July 23, 2012).

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2012-14-04, which applies to the specified
products. The NPRM was published in the Federal Register on March 26,
2013 (78 FR 18257), and proposed to correct an unsafe condition for the
specified products. Transport Canada Civil Aviation (TCCA), which is
the aviation authority for Canada, issued Canadian Airworthiness
Directive CF-2011-29R1, dated May 24, 2012 (the Mandatory Continuing
Airworthiness Information, referred to after this as ``the MCAI''), to
correct an unsafe condition for the specified products. The MCAI
states:
Seven cases of on-ground hydraulic accumulator screw cap or end
cap failure have been experienced on CL-600-2B19 * * * aeroplanes,
resulting in loss of the associated hydraulic system and high-energy
impact damage to adjacent systems and structure. To date, the lowest
number of flight cycles accumulated at the time of failure has been
6991.
Although there have been no failures to date on any DHC-8
aeroplanes, similar accumulators to those installed on the CL-600-
2B19, Part Numbers (P/N)08-60162-001 and 08-60162-002 (Parking Brake
Accumulator), are installed on the aeroplanes listed in the
Applicability section of this [TCCA] directive.
A detailed analysis of the systems and structure in the
potential line of trajectory of a failed screw cap/end cap for the
accumulator has been conducted. It has identified that the worst-
case scenarios would be the loss of number 2 hydraulic system, and
damage to aeroplane structures.
This [original TCCA] directive [which corresponds to FAA AD
2012-14-04, Amendment 39-17118 (77 FR 42956, July 23, 2012)] gives
instructions to determine the part number and serial number of the
existing parking brake accumulator, and where applicable, replace
the accumulator.
Revision 1 of this [TCCA] AD mandates the installation of
restraint devices around [all] the parking brake accumulator end
caps to hold them in place in the event of an end cap failure.
Uncontained failure of the parking brake accumulator screw caps and/or
end caps could result in loss of the number 2 hydraulic system, and
damage to airplane structures, and could adversely affect the
controllability of the airplane. 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 (78 FR 18257 March 26,
2013) 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 this AD as proposed-except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (78 FR 18257 March 26, 2013) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 18257 March 26, 2013).
Costs of Compliance
We estimate that this AD will affect about 129 products of U.S.
registry.
The actions that were required by AD 2012-14-04, Amendment 39-17118
(77 FR 42956, July 23, 2012), and retained in this AD take about 2
work-hours per product, at an average labor rate of $85 per work-hour.
Based on these figures, the estimated cost of the currently required
actions is $170 per product.
We estimate that it will take about 15 work-hours per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $5,302 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 $848,433, or $6,577 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 that 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);
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.
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 this AD, the regulatory evaluation,
