Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. 
This proposed AD was prompted by a determination that the existing 
instruction in a certain task in the aircraft maintenance manual (AMM)

[[Page 45998]]

will not accomplish the intent of a certification maintenance 
requirement (CMR). This CMR task tests the pitch feel (PF) and rudder 
travel limiter actuator (RTLA) back-up modules in the flight control 
unit (FCU) to detect dormant failures. This proposed AD would require 
doing an operational test of the FCU back-up modules, and repair if 
necessary. We are proposing this AD to detect and correct a dormant 
failure of both FCU back-up modules. This condition, in combination 
with other failures in the FCU, may result in the inability to maintain 
the minimum control requirements for the PF and RTLA, which could 
create hazardous flight control inputs during flight.

DATES: We must receive comments on this proposed AD by August 29, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-06R1, dated April 22, 2015 (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:

    It was discovered that the existing instruction in the Aircraft 
Maintenance Manual (AMM) Task 27-61-05-710-801 will not accomplish 
the intent of the Certification Maintenance Requirement (CMR) task 
number 27-61-05-201. This CMR task was required to test the Pitch 
Feel (PF) and Rudder Travel Limiter Actuator (RTLA) back-up modules 
in the Flight Control Unit (FCU) to detect dormant failures. If not 
detected, a dormant failure of both FCU back-up modules, in 
combination with other failures in the FCU, may result in the 
inability to maintain the Minimum Control Requirements for the PF 
and RTLA, which could create hazardous flight control inputs during 
flight.
    The original issue of this [Canadian] AD mandated the 
performance of an operational test of the FCU back-up modules using 
the proper AMM task instructions [and repair if necessary].
    Revision 1 of this [Canadian] AD is to correct the model number 
designation in the Applicability section.

    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-
8177.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information. This service 
information describes procedures for doing an operational test of the 
FCU back-up modules.

    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.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Differences Between This Proposed AD and the MCAI or Service 
Information

    The MCAI specifies accomplishing an operational test of the FCU 
back-up modules, but does not specify a corrective action if the test 
is failed. If any FCU fails any operational test, this proposed AD 
would require repair using a method approved by the Manager, New York 
Aircraft Certification Office (ACO), ANE-170, FAA; or TCCA; or

[[Page 45999]]

Bombardier, Inc.'s TCCA Design Approval Organization (DAO).

Costs of Compliance

    We estimate that this proposed AD affects 76 airplanes of U.S. 
registry.
    We also estimate that it would take about 3 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $19,380, or $255 
per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this NPRM.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
