Amendment 39-18622; AD 2016-17-09]
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 all 
Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) and CL-
600-2D24 (Regional Jet Series 900) airplanes. This AD was prompted by 
two in-service incidents reported on Bombardier, Inc. Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702) airplanes regarding a loss of all 
air data information in the flight deck. This AD requires revision of 
the airplane flight manual (AFM) to provide procedures to guide the 
crew to stabilize the airplane's airspeed and attitude for continued 
safe flight. We are issuing this AD to prevent loss of air data 
information that may affect continued safe flight.

DATES: This AD is effective September 30, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
30, 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 all Bombardier, Inc. Model 
CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet 
Series 900) airplanes. The NPRM published in the Federal Register on 
March 4, 2016 (81 FR 11467) (``the NPRM''). The NPRM was prompted by 
two in-service incidents reported on Bombardier, Inc. Model CL-600-2C10 
(Regional Jet Series 700, 701, & 702) airplanes regarding a loss of all 
air data information in the flight deck. The NPRM proposed to require 
revision of the airplane flight manual (AFM) to provide procedures to 
guide the crew to stabilize the airplane's airspeed and attitude for 
continued safe flight. We are issuing this AD to prevent loss of air 
data information that may affect continued safe flight.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2015-08, dated April 
28, 2015 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Bombardier, Inc. Model CL-600-2D15 (Regional Jet 
Series 705) and CL-600-2D24 (Regional Jet Series 900) 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 aeroplanes 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-
3990.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM and 
the FAA's response to each comment.

Request for Further Investigation

    The Air Line Pilots Association stated that the AFM revision will 
not address the root cause of the high-altitude icing (ice crystal 
contamination), and requested that further investigation be done for 
the ice crystal contamination issue and remedies be provided in 
addition to the AFM amendments.
    We agree that the AFM revision will not address the root cause of 
the high-altitude icing (ice crystal contamination). The manufacturer 
is investigating the issue, but there is no timetable for a final 
resolution. Should the manufacturer develop modifications to prevent 
this problem, the FAA will consider further rulemaking. The 
incorporation of the AFM procedures is meant to be used to guide the 
crew on how to stabilize the airplane airspeed and altitude for 
continued safe flight in icing conditions. However, further 
investigation into this matter extends beyond the scope of this AD.

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 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.

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.
