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:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Replace FCC........................ 3 work-hours x $85 per hour $2,800 $3,055 $3,079,440
= $255 per airplane.

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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979);
-
Will not affect intrastate aviation in Alaska; and
-
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.
