Amendment 39-18022; AD 2014-23-06]

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-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This AD was prompted by a report indicating that inboard and 
outboard hydraulic lines of the brakes were found connected to the 
incorrect ports on the swivel assembly of the main landing gear (MLG). 
This AD requires modifying the MLG by installing a new bracket on the 
left and right lower aft-wing planks. We are issuing this AD to prevent 
incorrect installation of the brake hydraulic lines, which could cause 
the brakes and the anti-skid system to operate incorrectly, and 
consequent catastrophic failure of the airplane during a high-speed 
rejected takeoff.

DATES: This AD becomes effective December 26, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 26, 
2014.

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-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on August 4, 2014 (79 FR 45135).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-10, dated February 12, 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-
2B19 (Regional Jet Series 100 & 440) airplanes. The MCAI states:

    Cases of inboard and outboard hydraulic brake lines connected to 
the incorrect port of the swivel assembly on the main landing gear 
were found in service, including a runway overrun event. Cross-
connected brake hydraulic lines can cause the brakes and/or the 
anti-skid system to operate incorrectly. During a high speed 
rejected take-off, inability for the brakes to operate correctly 
could be catastrophic.
    This [Canadian] AD mandates the modification to prevent 
inadvertent cross-connection of the inboard and outboard hydraulic 
brake lines.

    The required action in this AD includes installing a new bracket on 
the left and right lower aft-wing planks of the MLG. You may examine 
the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0489-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 45135, August 4, 
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 45135, August 4, 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 45135, August 4, 2014).

Costs of Compliance

    We estimate that this AD affects 526 airplanes of U.S. registry.
    We also estimate that it will take about 6 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $375 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $465,510, or $885 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.

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2014-0489; 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.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2014-23-06 Bombardier, Inc.: Amendment 39-18022. Docket No. FAA-
2014-0489; Directorate Identifier 2014-NM-048-AD.
