We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes, Model DHC-8-200 series airplanes, and Model DHC-8-300 series airplanes. This proposed AD was prompted by several occurrences of loss of airspeed data on both pilot and co-pilot air speed indicators due to the accumulation of ice on the pitot probes. An investigation revealed that the accumulation of ice was due to inoperative pitot probe heaters. This proposed AD would require replacing the existing circuit breakers in both the left and right side of the pitot heater system with circuit breakers that have higher trip points. We are proposing this AD to prevent circuit breakers from tripping and cutting power supply to the pitot probe heater, which could cause loss of airspeed data and result in the flightcrew not being able to control the airspeed of the airplane.

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 
certain Bombardier, Inc. Model DHC-8-102, -103, and -106 airplanes, 
Model DHC-8-200 series airplanes, and Model DHC-8-300 series airplanes. 
This proposed AD was prompted by several occurrences of loss of 
airspeed data on both pilot and co-pilot air speed indicators due to 
the accumulation of ice on the pitot probes. An investigation revealed 
that the accumulation of ice was due to inoperative pitot probe 
heaters. This proposed AD would require replacing the existing circuit 
breakers in both the left and right side of the pitot heater system 
with circuit breakers that have higher trip points. We are proposing 
this AD to prevent circuit breakers from tripping and cutting power 
supply to the pitot probe heater, which could cause loss of airspeed 
data and result in the flightcrew not being able to control the 
airspeed of the airplane.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2016-04, dated February 
1, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc. Model DHC-8-102, -103, and -106 
airplanes, Model DHC-8-200 series airplanes, and Model DHC-8-300 series 
airplanes. The MCAI states:

    There have been several occurrences of loss of airspeed data on 
both pilot and co-pilot Airspeed Indicators (ASI) due to the 
accumulation of ice on the pitot probes. Subsequent investigation 
revealed that the build up of ice on the pitot probes was due to 
inoperative pitot probe heaters. When flying in heavy 
precipitations, the increased heat required by the pitot probe to 
clear ice build up may result in a current demand in excess of the 
trip point of the associated circuit breakers (CB). Under this 
condition, the CB may trip and cut power supply to the heater. If 
not corrected, the loss of airspeed data may result in the crew not 
being able to control the aeroplane's airspeed.
    This [Canadian] AD is issued to mandate the replacement of the 
existing CBs with CBs that have higher trip points.

    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-
7267.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 8-30-39, dated November 11, 
2015, and Bombardier Service Bulletin 8-30-40, dated November 11, 2015. 
The service information describes replacing the existing circuit 
breakers in both the left and right side of the pitot heater system 
with circuit breakers that have higher trip points. 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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 83 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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 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.
