SUPPLEMENTARY INFORMATION:
We are adopting a new
airworthiness directive (AD) for certain
Bombardier, Inc. Model DHC–8–400
series airplanes. This AD was prompted
by reports of hydraulic fluid loss from
the reservoir of the main landing gear
(MLG) alternate extension system. This
AD requires inspection for correct
assembly of the MLG alternate extension
system reservoir lid, and corrective
action if necessary. We are issuing this
AD to, in the event of a failure of the
primary MLG extension system, prevent
failure of the alternate MLG extension
system to fully extend the MLG into a
down-and-locked position, which could
result in collapse of both left-hand and
right-hand MLG sides during
touchdown.
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would
apply to certain Bombardier, Inc. Model
DHC–8–400 series airplanes. The NPRM
published in the Federal Register on
October 23, 2014 (79 FR 63341).
Transport Canada Civil Aviation
(TCCA), which is the aviation authority
for Canada, has issued Canadian
Airworthiness Directive CF–2014–15,
dated June 6, 2014 (referred to after this
as the Mandatory Continuing
Airworthiness Information, or ‘‘the
MCAI’’), to correct an unsafe condition
for certain Bombardier, Inc. Model
DHC–8–400 series airplanes. The MCAI
states:
This AD becomes effective July
14, 2015.
The Director of the Federal Register
approved the incorporation by reference
of a certain publication listed in this AD
as of July 14, 2015.

position, resulting in an unsafe landing
configuration.
This [Canadian] AD mandates the [general
visual] inspection of the MLG alternate
extension system reservoir lid for correct
assembly and the required rectification [i.e.,
corrective action which consists of repairing
the lid assembly].

Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM (79
FR 63341, October 23, 2014) or on the
determination of the cost to the public.
Conclusion
We reviewed the relevant 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 (79 FR
63341, October 23, 2014) for correcting
the unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (79 FR 63341,
October 23, 2014).
Related Service Information Under 1
CFR Part 51
Bombardier has issued Service
Bulletin 84–29–34, dated May 9, 2013,
with the attached Parker Service
Bulletin 82910012–29–431, dated
October 22, 2012. This service
information describes procedures to
inspect the lid assembly of the MLG
alternate extension system reservoir for
correct assembly and corrective actions.
This service information is reasonably
available because the interested parties
have access to it through their normal
course of business or by the means
identified in the ADDRESSES section of
this AD.
Costs of Compliance
We estimate that this AD affects 173
airplanes of U.S. registry.
We also estimate that it will take
about 4 work-hours per product to
comply with the basic requirements of
this AD. The average labor rate is $85
per work-hour. Based on these figures,
we estimate the cost of this AD on U.S.
operators to be $58,820, or $340 per
product.
In addition, we estimate that any
necessary follow-on actions will take

about 2 work-hours and require parts
costing $0, for a cost of $170 per
product. We have no way of
determining the number of aircraft that
might need this action.
Authority for This Rulemaking

section.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
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.
Adoption of the Amendment
Regulatory Findings
(b) Affected ADs
None.
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.

Discussion
This AD action was prompted by EAD
No. 2014–0040–E, dated February 19,
2014, issued by EASA, which is the
Technical Agent for the Member States
of the European Union, to correct an
unsafe condition for certain
AgustaWestland S.p.A. Model AB 412
and AB 412 EP helicopters. EASA
advises that a crack was found in an
adapter, part number (P/N) 412–040–
622–101, installed on a Model AB 412
EP helicopter. EASA further advises that
the condition, if not detected and
corrected, could lead to T/R drive shaft
failure, possibly resulting in reduced
control of the helicopter. To address this
unsafe condition, the EASA EAD
requires repetitive inspections of
adapters, P/N 412–040–622–101 and P/
N 412–040–623–101, for a crack and
replacing a cracked adapter. EASA also
requires reporting and sending the
cracked adapter to AgustaWestland for
investigation.
FAA’s Determination
These helicopters have been approved
by the aviation authority of Italy and are
approved for operation in the United
States. Pursuant to our bilateral
agreement with Italy, the EASA, its
technical representative, has notified us
of the unsafe condition described in the
EASA AD. We are issuing this AD
because we evaluated all information
provided by the EASA and determined
the unsafe condition exists and is likely
to exist or develop on other helicopters
of these same type designs.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc.
Model DHC-8-400 series airplanes. The NPRM published in the Federal
Register on October 23, 2014 (79 FR 63341).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-15, dated June 6, 2014 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model DHC-8-400 series
airplanes. The MCAI states:
Several cases have been reported of hydraulic fluid loss from the
main landing gear (MLG) alternate extension system reservoir and in
one case, the reservoir was found empty. The cause was determined to
be an incorrectly assembled reservoir lid. In the event of a failed
primary MLG extension system, an alternate MLG extension system with
an empty reservoir may not be able to fully extend the MLG into the
down and locked position, resulting in an unsafe landing
configuration.
This [Canadian] AD mandates the [general visual] inspection of the
MLG alternate extension system reservoir lid for correct assembly
and the required rectification [i.e., corrective action which
consists of repairing the lid assembly].

Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 63341, October 23,
2014) or on the determination of the cost to the public.
Conclusion
We reviewed the relevant 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 (79 FR 63341, October 23, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 63341, October 23, 2014).
Related Service Information Under 1 CFR Part 51
Bombardier has issued Service Bulletin 84-29-34, dated May 9, 2013,
with the attached Parker Service Bulletin 82910012-29-431, dated
October 22, 2012. This service information describes procedures to
inspect the lid assembly of the MLG alternate extension system
reservoir for correct assembly and corrective actions. This service
information is reasonably available because the interested parties have
access to it through their normal course of business or by the means
identified in the ADDRESSES section of this AD.
Costs of Compliance
We estimate that this AD affects 173 airplanes of U.S. registry.
We also estimate that it will take about 4 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Based on these figures, we estimate the cost
of this AD on U.S. operators to be $58,820, or $340 per product.
In addition, we estimate that any necessary follow-on actions will
take
[[Page 32450]]
about 2 work-hours and require parts costing $0, for a cost of $170 per
product. We have no way of determining the number of aircraft that
might need this action.
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.

reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, 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 airworthiness
directive (AD):
2015-10-01 Bombardier, Inc.: Amendment 39-18156. Docket No. FAA-
2014-0754; Directorate Identifier 2014-NM-136-AD.
(a) Effective Date
This AD becomes effective July 14, 2015.
(b) Affected ADs
None.
(c) Applicability
This AD applies to Bombardier, Inc. Model DHC-8-401, -402, and -
