14 CFR Part 39
[Docket No. FAA-2014-0754; Directorate Identifier 2014-NM-136-AD;
Amendment 39-18156; AD 2015-10-01]

Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: 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.
DATES: 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.

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].
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0754-0002.
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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0754; or in person at the
Docket Management Facility 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.
