[FR Doc. 2013–09006 Filed 4–16–13; 8:45 am] BILLING CODE 4910–13–P DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2013–0332; Directorate Identifier 2013–NM–009–AD] 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 CL–600–2B16 (CL–601–3A, CL–601–3R, and CL–604 Variants) airplanes. This proposed AD was prompted by reports of airspeed mismatch between the pilot and copilot’s airspeed indicators, which occurred during or after heavy rain. This proposed AD would require, for certain airplanes, inspecting for drain bottles having certain part numbers, and replacing affected drain bottles. This proposed AD would require, for certain other airplanes, replacing drain bottles. We are proposing this AD to prevent pitot static tubing from becoming blocked by water, which if not corrected, could lead to erroneous airspeed and altitude indications, and consequent loss of control of the airplane. SUMMARY: We must receive comments on this proposed AD by June 3, 2013. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Discussion Transport Canada Civil Aviation, which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2012–30, dated December 7, 2012 (referred to after this as the Mandatory Continuing PO 00000 Frm 00006 Fmt 4702 Sfmt 4702 Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for the specified products. The MCAI states: A number of reports were received from the operators indicating airspeed mismatch between the pilot and co-pilot’s airspeed indicators. The erroneous indication occurred during or after heavy rain. Further investigation revealed that during heavy precipitation, the pitot static tubing may become partially or completely blocked by the water which didn’t enter the drain bottle(s). This condition, if not corrected, may result in erroneous airspeed and altitude indications [and consequent loss of control of the airplane]. This [Canadian] AD mandates [for certain airplanes] the replacement of the drain bottles to improve drainage of the pitot-static tubing [and, for certain other airplanes, an inspection for, and replacement of, certain drain bottles]. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information Bombardier, Inc. has issued the following service bulletins. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. • Bombardier Service Bulletin 601– 0617, Revision 03, dated December 20, 2012. • Bombardier Service Bulletin 604– 34–065, Revision 02, dated December 20, 2012. • Bombardier Service Bulletin 605– 34–027, Revision 02, dated December 20, 2012. 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 Based on the service information, we estimate that this proposed AD would affect about 77 products of U.S. registry. We also estimate that it would take about 5 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 up to $2,939 per E:\FR\FM\17APP1.SGM 17APP1 Federal Register / Vol. 78, No. 74 / Wednesday, April 17, 2013 / Proposed Rules product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these parts. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $259,028, or $3,364 per product. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Authority for This Rulemaking PART 39—AIRWORTHINESS DIRECTIVES 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. tkelley on DSK3SPTVN1PROD with PROPOSALS 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket. VerDate Mar<15>2010 16:35 Apr 16, 2013 Jkt 229001 The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: 1.

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 CL-600-2B16 (CL-601-3A, CL-601-3R, and 
CL-604 Variants) airplanes. This proposed AD was prompted by reports of 
airspeed mismatch between the pilot and co-pilot's airspeed indicators, 
which occurred during or after heavy rain. This proposed AD would 
require, for certain airplanes, inspecting for drain bottles having 
certain part numbers, and replacing affected drain bottles. This 
proposed AD would require, for certain other airplanes, replacing drain 
bottles. We are proposing this AD to prevent pitot static tubing from 
becoming blocked by water, which if not corrected, could lead to 
erroneous airspeed and altitude indications, and consequent loss of 
control of the airplane.

DATES: We must receive comments on this proposed AD by June 3, 2013.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    Transport Canada Civil Aviation, which is the aviation authority 
for Canada, has issued Canadian Airworthiness Directive CF-2012-30, 
dated December 7, 2012 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for the specified products. The MCAI states:

A number of reports were received from the operators indicating 
airspeed mismatch between the pilot and co-pilot's airspeed 
indicators. The erroneous indication occurred during or after heavy 
rain. Further investigation revealed that during heavy 
precipitation, the pitot static tubing may become partially or 
completely blocked by the water which didn't enter the drain 
bottle(s). This condition, if not corrected, may result in erroneous 
airspeed and altitude indications [and consequent loss of control of 
the airplane].

This [Canadian] AD mandates [for certain airplanes] the replacement 
of the drain bottles to improve drainage of the pitot-static tubing 
[and, for certain other airplanes, an inspection for, and 
replacement of, certain drain bottles].

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Bombardier, Inc. has issued the following service bulletins. The 
actions described in this service information are intended to correct 
the unsafe condition identified in the MCAI.
     Bombardier Service Bulletin 601-0617, Revision 03, dated 
December 20, 2012.
     Bombardier Service Bulletin 604-34-065, Revision 02, dated 
December 20, 2012.
     Bombardier Service Bulletin 605-34-027, Revision 02, dated 
December 20, 2012.

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

    Based on the service information, we estimate that this proposed AD 
would affect about 77 products of U.S. registry. We also estimate that 
it would take about 5 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 up to $2,939 per

[[Page 22807]]

product. Where the service information lists required parts costs that 
are covered under warranty, we have assumed that there will be no 
charge for these parts. As we do not control warranty coverage for 
affected parties, some parties may incur costs higher than estimated 
here. Based on these figures, we estimate the cost of the proposed AD 
on U.S. operators to be $259,028, or $3,364 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new AD:

Bombardier, Inc.: Docket No. FAA-2013-0332; Directorate Identifier 
2013-NM-009-AD.

(a) Comments Due Date

    We must receive comments by June 3, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the airplanes specified in paragraphs (c)(1) 
and (c)(2) of this AD, certificated in any category.
    (1) Bombardier, Inc. Model CL-600-2B16 (CL-601-3A and CL-601-3R 
Variants) airplanes, serial numbers 5001 through 5194 inclusive.
    (2) Bombardier, Inc. Model CL-600-2B16 (CL-604 Variant) 
airplanes, serial numbers 5301 through 5665 inclusive, and 5701 
through 5918 inclusive.

(d) Subject

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

(e) Reason

    This AD was prompted by reports of airspeed mismatch between the 
pilot and co-pilot's airspeed indicators, which occurred during or 
after heavy rain. We are issuing this AD to prevent pitot static 
tubing from becoming blocked by water, which if not corrected, could 
lead to erroneous airspeed and altitude indications, and consequent 
loss of control of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Inspection and Replacement for Certain Model CL-600-2B16 (CL-601-3A
