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 BD-700-1A10 and BD-700-1A11 airplanes. This AD 
was prompted by a report of several events where pilots experienced 
difficulty in lateral control of the airplane after doing a climb 
through heavy rain conditions and a determination that the cause was 
water ingress in the aileron control pulley assembly. This AD requires, 
for certain airplanes, inspecting for correct clearance and rework if 
necessary, and, for certain other airplanes, installing a cover for the 
aileron pulley assembly. We are issuing this AD to prevent water 
ingress in the aileron control pulley assembly, which could freeze in 
cold conditions and result in reduced control of the airplane.

DATES: This AD becomes effective September 29, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 29, 
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 BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the 
Federal Register on March 30, 2015 (80 FR 16608).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-23, dated July 18, 2014 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model BD-700-1A10 and BD-
700-1A11 airplanes. The MCAI states:

    There have been several reports whereby pilots have experienced 
difficulty in lateral control following climb through heavy rain 
conditions. In each event, the pilots were able to overcome this 
difficulty without disconnecting the aileron control. An 
investigation has determined that the root cause of the restricted 
movement of the aileron was due to water ingress into the wing root 
aileron control pulley assembly through a gap on the wing-to-
fuselage fairing resulting in freezing of the aileron control 
system.

[[Page 51462]]

    If not corrected, this condition could result in reduced lateral 
control of the aeroplane.
    This [Canadian] AD mandates [for certain airplanes] the 
incorporation of a cover for the aileron pulley assembly [and 
inspection and rework if necessary] to prevent water ingress in the 
aileron control pulley assembly [and for certain other airplanes, 
mandates an inspection and rework if necessary].

    The inspection involves doing a general visual inspection for 
correct clearance. You may examine the MCAI in the AD docket on the 
Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2015-
0676-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 16608, March 30, 
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 16608, March 30, 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 16608, March 30, 2015).

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
     Service Bulletin 700-1A11-27-034, Revision 04, dated 
September 4, 2014;
     Service Bulletin 700-27-076, Revision 04, dated September 
4, 2014;
     Service Bulletin 700-27-5004, Revision 04, dated September 
4, 2014; and
     Service Bulletin 700-27-6004, Revision 04, dated September 
4, 2014.
    This service information describes procedures, for certain 
airplanes, for installing a cover for the No. 1 aileron pulley, 
including an inspection for correct clearance and rework, and for 
certain other airplanes, for an inspection for correct clearance and 
rework. 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 60 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. Based on these figures, we estimate the cost 
of this AD on U.S. operators to be $45,900, or $765 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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.

regulatory evaluation, any comments received, and other information.
