Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian AD CF–2017–08, dated March 8, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL–600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states: Malfunctions of the landing gear AlternateExtension System (AES) have been experienced. Failure of the landing gear AES could prevent the landing gear from extending in the case of a failure of the primary landing gear extension system. This [Canadian] AD is issued to mandate the replacement of the [nose landing gear] NLG and [main landing gear] MLG [electromechanical actuators] EMA P/Ns BA698– 85006–1 and BA698–85007–1. 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–2017– 0512. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Service Bulletin 670BA–32–047, Revision A, dated December 5, 2016. The service information describes procedures for replacing certain nose landing gear and main landing gear electro-mechanical actuators. 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 section. ADDRESSES 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 39 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Cost per product Action Labor cost Parts cost Replacement ..................... 4 work-hours × $85 per hour = $340 ........................ Not available .................... 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 available costs in our cost estimate. nlaroche on DSK30NT082PROD 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. VerDate Sep<11>2014 13:14 Jun 01, 2017 Jkt 241001 Cost on U.S. operators $340 $13,260 Regulatory Findings The Proposed Amendment 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 Administrator, the FAA proposes to amend 14 CFR part 39 as follows: List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new airworthiness directive (AD): ■ Bombardier, Inc.: Docket No. FAA–2017– 0512; Directorate Identifier 2017–NM– 031–AD.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2017-08, dated March 8, 
2017 (referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc., Model CL-600-2E25 (Regional Jet Series 1000) 
airplanes. The MCAI states:

    Malfunctions of the landing gear Alternate-Extension System 
(AES) have been experienced. Failure of the landing gear AES could 
prevent the landing gear from extending in the case of a failure of 
the primary landing gear extension system.
    This [Canadian] AD is issued to mandate the replacement of the 
[nose landing gear] NLG and [main landing gear] MLG [electro-
mechanical actuators] EMA P/Ns BA698-85006-1 and BA698-85007-1.

    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-2017-
0512.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Service Bulletin 670BA-32-047, Revision A, 
dated December 5, 2016. The service information describes procedures 
for replacing certain nose landing gear and main landing gear electro-
mechanical actuators. 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 39 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

    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 available 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.

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]

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

Bombardier, Inc.: Docket No. FAA-2017-0512; Directorate Identifier 
2017-NM-031-AD.

(a) Comments Due Date

    We must receive comments by July 17, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc., Model CL-600-2E25 (Regional 
Jet Series 1000) airplanes, certificated in any category, serial 
numbers 19001 through 19039 inclusive.

[[Page 25547]]

(d) Subject

    Air Transport Association (ATA) of America Code 32, Landing 
gear.

(e) Reason

    This AD was prompted by failures of the landing gear alternate-
extension system (AES). We are issuing this AD to prevent failure of 
the landing gear AES and consequent landing with some or all of the 
landing gear not extended.

(f) Compliance

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

(g) Replacement

    Within 1,200 flight hours or 12 months after the effective date 
of this AD, whichever occurs first: Replace the nose landing gear 
(NLG) and main landing gear (MLG) electro-mechanical actuators (EMA) 
having part numbers (P/Ns) BA698-85006-1 and BA698-85007-1 with P/Ns 
BA698-85006-3 and BA698-85007-3, as applicable, in accordance with 
the Accomplishment Instructions of Bombardier Service Bulletin 
670BA-32-047, Revision A, dated December 5, 2016 (``670BA-32-047, 
RA''). Where 670BA-32-047, RA, instructs operators to contact 
Bombardier if it is not possible to complete all the instructions in 
670BA-32-047, RA, because of the configuration of the airplane, this 
AD requires that any deviation from the instructions provided in 
670BA-32-047, RA, must be approved as an alternative method of 
compliance (AMOC) under the provisions of paragraph (j)(1) of this 
AD.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install an 
NLG or MLG EMA having P/N BA698-85006-1 or BA698-85007-1, on any 
airplane.

(i) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using Bombardier Service Bulletin 670BA-32-047, 
dated February 28, 2014.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
