Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-5590; Directorate Identifier 2016-NM-018-AD; 
Amendment 39-18588; AD 2016-14-07
RIN 2120-AA64

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), 
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-
2D15 (Regional Jet Series 705), Model CL-600-2D24 (Regional Jet Series 
900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This 
AD was prompted by reports of undesirable changes in the Reference 
Airspeed (RAS) Bug, occurring during flight without pilot input. This 
AD requires replacing the flight control computer (FCC). We are issuing 
this AD to prevent uncommanded pitch changes, which could result in 
deviation from a safe flight path.

DATES: This AD is effective August 16, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 16, 
2016.

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), Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet 
Series 705), Model CL-600-2D24 (Regional Jet Series 900), and Model CL-
600-2E25 (Regional Jet Series 1000) airplanes. The NPRM published in 
the Federal Register on April 14, 2016 (81 FR 22037) (``the NPRM''). 
The NPRM was prompted by reports of undesirable changes in the RAS Bug, 
occurring during flight without pilot input. The NPRM proposed to 
require replacing the FCC. We are issuing this AD to prevent 
uncommanded pitch changes, which could result in deviation from a safe 
flight path.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-02, dated January 20, 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), Model CL-600-2C10 (Regional Jet 
Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), 
Model CL-600-2D24 (Regional Jet Series 900), and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. The MCAI states:

    There have been numerous reports of uncommanded changes in the 
Reference Airspeed (RAS) Bug during flight. When the Auto Flight 
Control System (AFCS) is in a speed mode (CLB, DES, IAS or MACH), 
the flight director will show vertical guidance to achieve or 
maintain the reference airspeed. If the autopilot is engaged, the 
aeroplane will automatically follow that vertical guidance and cause 
the aeroplane to pitch up or pitch down. Investigation revealed that 
this uncommanded reference airspeed changes were caused by the FCC 
that did not correctly read the input data from the Input/Output 
Concentrator. If not corrected, these uncommanded pitch changes 
could create hazard for continued safe flight. This [Canadian] AD 
mandates installation of a new filter to the Input/Output Circuit 
Card in the FCC.

    Uncommanded pitch changes, if not corrected, could result in 
deviation from a safe flight path. Corrective actions include replacing 
the FCC. 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-2016-5590.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. The commenter supported 
the NPRM.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 601R-22-018, Revision A, 
dated November 3, 2015; and Service Bulletin 670BA-22-009, dated August 
17, 2015. The service information describes procedures for replacing 
the FCCs. 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 1,008 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
