SUPPLEMENTARY INFORMATION: RIN 2120–AA64 Airworthiness Directives; Bombardier, Inc. Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD–100–1A10 (Challenger 300) airplanes. This proposed 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 proposed AD would require replacement of the left and right pitotstatic probes with newly redesigned left and right pitot-static probes. We are proposing 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: We must receive comments on this proposed AD by September 14, 2015. rmajette on DSK2VPTVN1PROD with PROPOSALS SUMMARY: VerDate Sep<11>2014 13:28 Jul 30, 2015 Jkt 235001 45617 2015–NM–063–AD’’ at the beginning of your comments.

Discussion 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 https:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 3140. Comments Invited Related Service Information Under 1 CFR Part 51 We reviewed Bombardier 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 of this NPRM.

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 126 airplanes of U.S. registry. We also estimate that it would take about 12 work-hours per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Required parts would cost about $13,468 per product. Based on these figures, we estimate the cost of this proposed 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 proposed 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 have included all costs in our cost estimate. rmajette on DSK2VPTVN1PROD with PROPOSALS 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. VerDate Sep<11>2014 13:28 Jul 30, 2015 Jkt 235001 For the reasons discussed above, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2.

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 BD-100-1A10 (Challenger 300) airplanes. 
This proposed 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 proposed AD would require replacement of the left 
and right pitot-static probes with newly redesigned left and right 
pitot-static probes. We are proposing 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: We must receive comments on this proposed AD by September 14, 
2015.

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-2015-04, 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 https://www.regulations.gov by searching for and locating Docket No. FAA-2015-
3140.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier 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 of this 
NPRM.

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

[[Page 45618]]

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 126 airplanes of U.S. 
registry.
    We also estimate that it would take about 12 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about 
$13,468 per product. Based on these figures, we estimate the cost of 
this proposed 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 proposed 
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 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 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.

    Accordingly, under the authority delegated to me by the

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2015-3140; Directorate Identifier 
2015-NM-063-AD.

(a) Comments Due Date

    We must receive comments by September 14, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model BD-100-1A10 
(Challenger 300) airplanes, certificated in any category, serial 
numbers 20003 through 20500 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 34, Navigation.

(e) Reason

    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. 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.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Replacement of Left and Right Pitot-Static Probes

    Within 24 months after the effective date of this AD, replace 
the left and right pitot-static probes with newly designed pitot-
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.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install a 
pitot-static probe, P/N 0856WC1 or 0856WC2, on any airplane.
