Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-6415; Directorate Identifier 2015-NM-178-AD; 
Amendment 39-18626; AD 2016-17-13]
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-600-2C10 (Regional Jet Series 700, 701, & 
702) airplanes. This AD was prompted by two in-service incidents of a 
loss of all air data information in the flight deck. This AD requires a 
revision of the airplane flight manual (AFM) emergency procedures 
section to provide procedures to guide the crew on how to stabilize the 
airplane airspeed and attitude for continued safe flight when a loss of 
all air data information has occurred in the flight deck. We are 
issuing this AD to prevent loss of control when a loss of all air data 
information has occurred in the flight deck.

DATES: This AD is effective October 5, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 5, 
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-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes. The 
NPRM published in the Federal Register on May 10, 2016 (81 FR 28768) 
(``the NPRM''). The NPRM was prompted by two in-service incidents of a 
loss of all air data information in the flight deck. The NPRM proposed 
to require a revision of the AFM emergency procedures section to 
provide procedures to guide the crew on how to stabilize the airplane 
airspeed and attitude for continued safe flight when a loss of all air 
data information has occurred in the flight deck. We are issuing this 
AD to prevent loss of control when a loss of all air data information 
has occurred in the flight deck.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-20, dated July 21, 2015 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for certain Bombardier, Inc. Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702) airplanes. The MCAI states:

    Two in-service incidents have been reported on CL-600-2C10 
aeroplanes regarding a loss of all air data information in the 
cockpit. The air data information was recovered as the aeroplane 
descended to lower altitudes. An investigation determined that the 
root cause in both events was high altitude icing (ice crystal 
contamination). If not addressed, this condition may affect 
continued safe flight.
    Due to similarities in the air data systems, such events could 
happen on all Bombardier CRJ models, CL-600-2B19, CL-600-2C10, CL-
600-2D15, CL-600-2D24 and CL-600-2E25. Therefore, the corrective 
actions for these models will be mandated once their respective 
Airplane Flight Manual (AFM) revisions become available.
    This [Canadian] AD mandates the incorporation of AFM procedures 
to guide the crew to stabilize the aeroplane's airspeed and attitude 
for continued safe flight.

    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-
6415.

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 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 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

    Bombardier, Inc. has issued Section 03-19, ``Unreliable Airspeed,'' 
of Chapter 3, ``Emergency Procedures,'' in the Bombardier CRJ Series 
Regional Jet Model CL-600-2C10 Airplane Flight Manual CSP B-012, 
Revision 16A, dated November 6, 2015. The service information describes 
procedures to guide the crew to stabilize the airplane's airspeed and 
attitude for continued safe flight when a loss of all air data 
information has occurred in the flight deck. 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 269 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.
