DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2015-3140; Directorate Identifier 2015-NM-063-AD; 
Amendment 39-18385; AD 2016-02-05]
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 BD-100-1A10 (Challenger 300) airplanes. This AD 
was prompted by multiple reports of a short circuit between the heater 
element and the metal sheath of the pitot-static probe heater. This AD 
requires replacement of the left and right pitot-static probes with 
newly redesigned left and right pitot-static probes. We are issuing 
this AD to prevent degradation of the heating ability of the pitot-
static probe heater, resulting in erroneous airspeed indication during 
flight in icing conditions and consequent reduced controllability of 
the airplane.

DATES: This AD becomes effective March 8, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 8, 
2016.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2015-3140; or in person at the

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 BD-100-1A10 (Challenger 300) airplanes. The NPRM published in the 
Federal Register on July 31, 2015 (80 FR 45617).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2015-04, dated March 
17, 2015 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc. Model BD-100-1A10 (Challenger 
300) airplanes. The MCAI states:

    There have been several reports where the pitot-static probe 
heater came on and remained on regardless of the heater control 
selected position. Investigation determined that the root cause is a 
short circuit between the heater element and the metal sheath. If 
not corrected, this condition may degrade the heating, resulting in 
erroneous Airspeed Indication when flying in icing condition [and 
consequent reduced controllability of the airplane].
    This [Canadian] AD mandates the replacement of the pitot-static 
probes with a redesigned probe which will prevent this failure mode.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-3140-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (80 FR 45617, July 31, 
2015) 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 (80 FR 45617, July 31, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 45617, July 31, 2015).

Related Service Information Under 1 CFR Part 51

    Bombardier issued Service Bulletin 100-34-38, dated January 9, 
2014. The service information describes procedures for replacement of 
the left and right pitot-static probes with newly redesigned left and 
right pitot-static probes, part numbers 0856WC3 and 0856WC4 
respectively. 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 126 airplanes of U.S. registry.
    We also estimate that it will take about 12 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $13,468 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $1,825,488, or $14,488 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we

[[Page 5366]]

have included all costs in our cost estimate.

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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov/#!docketDetail;D=FAA-2015-3140; or in person at the 
Docket Management Facility between 9 a.m. and 5 p.m., Monday through 
Friday, except Federal holidays. The AD docket contains this AD, the 
regulatory evaluation, any comments received, and other information.

static probes, part numbers (P/N) 0856WC3 and 0856WC4 respectively, 
in accordance with the Accomplishment Instructions of Bombardier 
Service Bulletin 100-34-38, dated January 9, 2014.

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, FAA; or Transport Canada Civil Aviation (TCCA); or
