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.

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-

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.
