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 CL-600-2E25 (Regional Jet Series 1000)
airplanes. This AD was prompted by a determination that without an
effective maintenance task to maintain the airplane's inherent level of
safety, there is a potential that a dormant failure of the alternate
release system of the landing gear could occur. This AD requires
revising the maintenance or inspection program, as applicable, to
incorporate a maintenance task for an operational check of the electro-
mechanical actuator and release mechanism of the alternate extension
system for the nose landing gear and main landing gear. We are issuing
this AD to prevent failure of the alternate release system of the
landing gear, which could prevent the landing gear from extending
during a failure of the normal landing gear extension system.
DATES: This AD becomes effective June 4, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 4,
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 CL-600-2E25 (Regional Jet Series 1000) airplanes. The NPRM
published in the Federal Register on January 23, 2015 (80 FR 3498).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-16, dated June 11, 2014 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model CL-600-2E25
(Regional Jet Series 1000) airplanes. The MCAI states:
During a design review, an error was identified which led to the
development of a new certification maintenance requirement (CMR)
task. Without an effective maintenance task to maintain the
aeroplane's inherent level of safety, there is a potential that a
dormant failure of the alternate release system of the landing gear
could occur. Failure of the landing gear alternate release system
could prevent the landing gear from extending in the case of a
failure of the normal landing gear extension system.
This [Canadian] AD mandates the incorporation of a new
maintenance task to ensure operation of the landing gear alternate
extension system.
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0074-0003.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 3498, January 23,
2015) 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 (80 FR 3498, January 23, 2015) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 3498, January 23, 2015).
Related Service Information Under 1 CFR Part 51
Bombardier, Inc. has issued Temporary Revision (TR) ALI-0472, dated
February 27, 2014, to Section 1-32 of Part 2, Bombardier Airworthiness
Limitations, of the CRJ Series Regional Jet Maintenance Requirements
Manual, CSP B-053. This service information describes a maintenance
task for an operational check of the electro-mechanical actuator and
release mechanism of the alternate extension system for the nose
landing gear and main landing gear. The actions described in this
service information are intended to correct the unsafe condition
identified in the MCAI. This service information is reasonably
available at http://www.regulations.gov by searching for and locating
Docket No. FAA-2015-
[[Page 24199]]
0074. Or see ADDRESSES for other ways to access this service
information.
Costs of Compliance
We estimate that this AD affects 35 airplanes of U.S. registry.
We also estimate that it will take about 1 work-hour 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 $2,975, or $85 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.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2015-0074; 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.
