RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt 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 proposed 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 proposed AD
would 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 proposing this AD to prevent
loss of air data information that may affect continued safe flight.
DATES: We must receive comments on this proposed AD by April 18, 2016.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
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.
Required actions in this NPRM apply only to Bombardier, Inc. Model
CL-600-2D15 (Regional Jet Series 705) and CL-600-2D24 (Regional Jet
Series 900) airplanes; we may consider issuing further rulemaking on
the other Bombardier airplane models identified previously. 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.

Related Service Information Under 1 CFR Part 51
Bombardier, Inc. has issued Emergency Procedure 1; Unreliable
Airspeed, of Section 03-19, Emergency Procedures--Unreliable Airspeed,
of Chapter 3, Emergency Procedures, in Volume 1 of the Bombardier CRJ
Series Regional Jet Model CL-600-2D15 and CL-600-2D24 Airplane Flight
Manual CSP C-012, Revision 11A, dated May 25, 2015. The service
information describes procedures to guide the crew to stabilize the
airplane's airspeed and attitude for continued safe flight. 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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of these
same type designs.
Costs of Compliance
We estimate that this proposed AD affects 230 airplanes of U.S.
registry.
We also estimate that it would take about 1 work-hour per product
to comply with the basic requirements of this proposed AD. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the cost of this proposed AD on U.S. operators to be $19,550, or $85
per product.
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
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.

notify your appropriate principal inspector, or lacking a principal
inspector, the manager of the local flight standards district
office/certificate holding district office. The AMOC approval letter
must specifically reference this AD.
(2) Contacting the Manufacturer: For any requirement in this AD
to obtain corrective actions from a manufacturer, the action must be
accomplished using a method approved by the Manager, New York ACO,
ANE-170, Engine and Propeller Directorate, FAA; or Transport Canada
Civil Aviation (TCCA); or Bombardier, Inc.'s TCCA Design Approval
