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.

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) airplanes. The NPRM
published in the Federal Register on May 10, 2016 (81 FR 28764) (``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-
2015-12, dated June 23, 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-600-2B19
(Regional Jet Series 100 & 440) airplanes. The MCAI states:
Two in-service incidents have been reported on CL-600-2C10
aeroplanes
[[Page 60253]]
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 <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2016-
6414.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comment received on the NPRM and
the FAA's response to that comment.
Request To Determine Root Cause of Unsafe Condition
The Airline Pilots Association International (ALPA) requested
further investigation and system modifications for the ice crystal
contamination. ALPA stated that although the NPRM proposed an amendment
to the AFM procedures for the crew, it does not believe that this AFM
procedure addresses the root cause of the unsafe condition.
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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> 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-600-2B19 Airplane Flight Manual CSP A-012,
Revision 64B, dated December 8, 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 500 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.
