Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2013–24R1, dated December 24, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model CL– 600–2C10 (Regional Jet Series 700, 701, & 702), CL–600–2D15 (Regional Jet Series 705), and CL–600–2D24 (Regional Jet Series 900) airplanes. The MCAI states: It was discovered that there are no instructions for continued airworthiness for the Nose Landing Gear (NLG) alternate extension actuator. Without an effective maintenance task to maintain the aeroplane’s inherent level of safety, there is a potential that a dormant failure of the alternate release system of the NLG could occur. Failure of the NLG alternate release system could prevent the nose landing gear from extending in the case of a failure of the normal NLG extension system. This [TCCA] AD is to mandate the incorporation of a new maintenance task to prevent failure of the NLG alternate release system. Revision 1 of this [TCCA] AD changes the phase-in time to be based on the NLG manual release actuators instead of aeroplanes.

Related Service Information Bombardier has issued Task 320100– 225, ‘‘Restoration of the NLG Manual Release Actuator,’’ of Subject 1–32, Landing Gear, of Section 1, Systems and Powerplant Program, Volume 1 of Part 1, Maintenance Review Board Report, Revision 14, dated July 10, 2013, of the CRJ 700/900/1000 Maintenance Requirements Manual, CSP–B–053. This service information describes an airworthiness limitation task for the NLG alternate extension actuator. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. emcdonald on DSK67QTVN1PROD with PROPOSALS 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. This proposed AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, an operator might not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval of an alternative method of compliance (AMOC) in accordance with the provisions of paragraph (j)(1) of this proposed AD. The request should include a description of changes to the required inspections that will ensure the continued damage tolerance of the affected structure. Costs of Compliance We estimate that this proposed AD affects 416 airplanes of U.S. registry. We also estimate that it would take about 1 work-hour 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 $0 per product. VerDate Sep<11>2014 19:56 Jan 22, 2015 Jkt 235001 Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $35,360, or $85 per product. In addition, we estimate that any necessary follow-on actions would take about 1 work-hour and require parts costing $0, for a cost of $85 per product. We have no way of determining the number of aircraft that might need this action. 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 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. 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.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-24R1, dated December 24, 2013 (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-
2C10 (Regional Jet Series 700, 701, & 702), CL-600-2D15 (Regional Jet 
Series 705), and CL-600-2D24 (Regional Jet Series 900) airplanes. The 
MCAI states:

    It was discovered that there are no instructions for continued 
airworthiness for the Nose Landing Gear (NLG) alternate extension 
actuator. Without an effective maintenance task to maintain the 
aeroplane's inherent level of safety, there is a potential that a 
dormant failure of the alternate release system of the NLG could 
occur. Failure of the NLG alternate release system could prevent the 
nose landing gear from extending in the case of a failure of the 
normal NLG extension system.
    This [TCCA] AD is to mandate the incorporation of a new 
maintenance task to prevent failure of the NLG alternate release 
system.
    Revision 1 of this [TCCA] AD changes the phase-in time to be 
based on the NLG manual release actuators instead of aeroplanes.

Related Service Information

    Bombardier has issued Task 320100-225, ``Restoration of the NLG 
Manual Release Actuator,'' of Subject 1-32, Landing Gear, of Section 1, 
Systems and Powerplant Program, Volume 1 of Part 1, Maintenance Review 
Board Report, Revision 14, dated July 10, 2013, of the CRJ 700/900/1000 
Maintenance Requirements Manual, CSP-B-053. This service information 
describes an airworthiness limitation task for the NLG alternate 
extension actuator. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

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.
    This proposed AD requires revisions to certain operator maintenance 
documents to include new inspections. Compliance with these inspections 
is required by section 91.403(c) of the Federal Aviation Regulations 
(14 CFR 91.403(c)). For airplanes that have been previously modified, 
altered, or repaired in the areas addressed by these inspections, an 
operator might not be able to accomplish the inspections described in 
the revisions. In this situation, to comply with 14 CFR 91.403(c), the 
operator must request approval of an alternative method of compliance 
(AMOC) in accordance with the provisions of paragraph (j)(1) of this 
proposed AD. The request should include a description of changes to the 
required inspections that will ensure the continued damage tolerance of 
the affected structure.

Costs of Compliance

    We estimate that this proposed AD affects 416 airplanes of U.S. 
registry.
    We also estimate that it would take about 1 work-hour 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 $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $35,360, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 1 work-hour and require parts costing $0, for a cost of $85 
per product. We have no way of determining the number of aircraft that 
might need this action.

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]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2014-1046; Directorate Identifier 
2014-NM-021-AD.

(a) Comments Due Date

    We must receive comments by March 9, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the airplanes identified in paragraphs (c)(1) 
and (c)(2) of this AD, certificated in any category.
    (1) Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 
701, & 702) airplanes, serial number (S/N) 10002 and subsequent.
    (2) Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 
705), and CL-600-2D24 (Regional Jet Series 900) airplanes, S/N 15001 
and subsequent.

(d) Subject

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

(e) Reason

    This AD was prompted by a determination that no instructions for 
continued airworthiness exist for the nose landing gear (NLG) 
alternate extension actuator of the NLG alternate release system. We 
are issuing this AD to prevent failure of the NLG alternate release 
system and, if the normal NLG extension system also fails, failure 
of the NLG to extend, and consequent damage to the airplane and 
injury to occupants.

(f) Compliance

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

(g) Maintenance or Inspection Program Revision

    Within 30 days after the effective date of this AD, revise the 
maintenance or inspection program, as applicable, to incorporate the 
information specified in Task 320100-225, ``Restoration of the NLG 
Manual Release Actuator,'' of Subject 1-32, Landing Gear, of Section 
1, Systems and Powerplant Program, Volume 1 of Part 1, Maintenance 
Review Board Report, Revision 14, dated July 10, 2013, of the CRJ 
700/900/1000 Maintenance Requirements Manual, CSP-B-053. The

[[Page 3504]]

initial compliance time for the task is specified in paragraph (h) 
of this AD.

(h) Initial Task Compliance Time

    Before the accumulation of 20,000 total flight cycles, or within 
5,500 flight cycles after the effective date of this AD, whichever 
occurs first: Perform the initial restoration specified in Task 
320100-225, ``Restoration of the NLG Manual Release Actuator,'' of 
Subject 1-32, Landing Gear, of Section 1, Systems and Powerplant 
Program, Volume 1 of Part 1, Maintenance Review Board Report, 
Revision 14, dated July 10, 2013, of the CRJ 700/900/1000 
Maintenance Requirements Manual, CSP-B-053.

(i) No Alternative Actions and Intervals

    After accomplishing the revision required by paragraph (g) of 
this AD, no alternative actions (e.g., inspections) or intervals may 
be used unless the actions or intervals are approved as an 
alternative method of compliance (AMOC) in accordance with the 
procedures specified in paragraph (j)(1) of this AD.

(j) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, New
