Federal Register Volume 82, Issue 33 (February 21, 2017)

We are superseding Airworthiness Directive (AD) 2014-23-06 for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. AD 2014-23-06 required modifying the main landing gear (MLG) by installing a new bracket on the left and right lower aft-wing planks. This new AD requires modification of the MLG with an improved design. 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 MLG. We are issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-23-06 for 
certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 
440) airplanes. AD 2014-23-06 required modifying the main landing gear 
(MLG) by installing a new bracket on the left and right lower aft-wing 
planks. This new AD requires modification of the MLG with an improved 
design. 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 MLG. We are issuing this 
AD to address the unsafe condition on these products.

DATES: This AD is effective March 28, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 28, 
2017.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to supersede AD 2014-23-06, Amendment 39-18022 (79 FR 69037, 
November 20, 2014) (``AD 2014-23-06''). AD 2014-23-06 applied to 
certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 
440) airplanes. The NPRM published in the Federal Register on October 
24, 2016 (81 FR 73042). The NPRM 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 MLG. The 
NPRM proposed to require modification of the MLG with an improved 
design. 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 result in catastrophic failure of 
the airplane during a high-speed rejected takeoff.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-10R1, dated May 4, 2016 (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. 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. The original issue of this 
[Canadian] AD mandated the modification to prevent inadvertent 
cross-connection of the inboard and outboard hydraulic brake lines.
    Following the initial release of this [Canadian] AD, operators 
reported that the modifications required by Bombardier Service 
Bulletin (SB) 601R-32-110 Rev. NC., dated 19 December 2013, still 
have a potential for incorrect connection. Subsequently, the SB has 
been revised to introduce a modified design and this [Canadian] AD 
revision is issued to mandate the incorporation of the modified 
design.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9190.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available 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 for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 601R-32-110, Revision C, 
dated May 4, 2016. The service information describes procedures for 
modifying the MLG by installing a block on the left and right lower 
aft-wing planks. 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.

Costs of Compliance

    We estimate that this AD affects 526 airplanes of U.S. registry.
    We also estimate that it will take about 9 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 $190 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $502,330, or $955 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.
