(a) Applicability This AD applies to Model S–92A helicopters, serial numbers 92006 through 920084, certificated in any category. (b) Unsafe Condition This AD defines the unsafe condition as an installation that does not provide adequate clearance to prevent chafing between the high voltage electrical wires and hydraulic lines. This condition could result in fire and subsequent loss of control of the helicopter. (c) Effective Date This AD becomes effective May 1, 2014. (d) Compliance You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time. (e) Required Actions (1) Within 5 hours time-in-service, inspect the electrical wires and the hydraulic lines in the upper deck of the helicopter for chafing between electrical wires and hydraulic lines. If there is chafing between electrical wires and hydraulic lines, before further flight, replace the unairworthy wires or lines with airworthy wires or lines. (2) Within 5 hours TIS, inspect each clamp for correct installation as shown in Figures 1 through 14 of Sikorsky Aircraft Corporation Alert Service Bulletin No. 92–20–001, dated October 27, 2005 (ASB).

SUPPLEMENTARY INFORMATION: DATES: 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 CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes, Model CL–600– 2D15 (Regional Jet Series 705) airplanes, Model CL–600–2D24 (Regional Jet Series 900) airplanes, and Model CL– 600–2E25 (Regional Jet Series 1000) airplanes. The NPRM published in the Federal Register on January 2, 2014 (79 FR 70). E:\FR\FM\16APR1.SGM 16APR1 21388 Federal Register / Vol. 79, No. 73 / Wednesday, April 16, 2014 / Rules and Regulations Transport Canada Civil Aviation (TCCA), which is the airworthiness authority for Canada, has issued Canadian Airworthiness Directive CF– 2013–31, dated October 8, 2013 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition. The MCAI states: It was discovered that for certain slat system jam-disconnect failure cases, the resulting slat skew could lead to failure of the eccentric pin at the slat track 3–3 attachment. If the pin migrates out of the attachment lugs, this could cause the No. 3 slat panels to disconnect from the wing and could lead to the loss of the aeroplane. This [Canadian] AD mandates the replacement of the locking plate with an antimigration assembly on both the left and right No. 3 slats. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov/ #!documentDetail;D=FAA-2013-10690002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (79 FR 70, January 2, 2014) or on the determination of the cost to the public. pmangrum on DSK3VPTVN1PROD with RULES 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 (79 FR 70, January 2, 2014) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (79 FR 70, January 2, 2014). Costs of Compliance We estimate that this AD affects 401 airplanes of U.S. registry. We also estimate that it will take about 9 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 $780 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $619,545, or $1,545 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 have included all costs in our cost estimate. VerDate Mar<15>2010 14:43 Apr 15, 2014 Jkt 232001 Authority for This Rulemaking List of Subjects in 14 CFR Part 39 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. Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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.

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 CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes, 
Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-
2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. The NPRM published in the Federal 
Register on January 2, 2014 (79 FR 70).

[[Page 21388]]

    Transport Canada Civil Aviation (TCCA), which is the airworthiness 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2013-31, dated October 8, 2013 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition. The MCAI states:

    It was discovered that for certain slat system jam-disconnect 
failure cases, the resulting slat skew could lead to failure of the 
eccentric pin at the slat track 3-3 attachment. If the pin migrates 
out of the attachment lugs, this could cause the No. 3 slat panels 
to disconnect from the wing and could lead to the loss of the 
aeroplane.
    This [Canadian] AD mandates the replacement of the locking plate 
with an anti-migration assembly on both the left and right No. 3 
slats.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-1069-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (79 FR 70, January 2, 
2014) 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 (79 FR 70, January 2, 2014) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (79 FR 70, January 2, 2014).

Costs of Compliance

    We estimate that this AD affects 401 airplanes of U.S. registry.
    We also estimate that it will take about 9 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 $780 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $619,545, or $1,545 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 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

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 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):

2014-08-03 Bombardier, Inc. Amendment 39-17827. Docket No. FAA-2013-
1069; Directorate Identifier 2013-NM-197-AD.

(a) Effective Date

    This AD becomes effective May 21, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. airplanes, certificated in 
any category, identified in paragraphs (c)(1), (c)(2), and (c)(3) of 
this AD.
    (1) Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 
701, & 702) airplanes, serial numbers 10002 through 10335 inclusive.
    (2) Bombardier, Inc. Model CL-600-2D15 (Regional Jet Series 705) 
airplanes, and Bombardier, Inc. Model CL-600-2D24 (Regional Jet 
Series 900) airplanes, serial numbers 15001 through 15293 inclusive.
    (3) Bombardier, Inc. Model CL-600-2E25 (Regional Jet Series 
1000) airplanes, serial numbers 19002 through 19036 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
controls.

(e) Reason

    This AD was prompted by a determination that for certain slat 
system jam-disconnect failure cases, the resulting slat skew could 
lead to failure of the eccentric pin at the slat track attachment. 
If the pin migrates out of the attachment lugs, this could cause 
certain slat panels to disconnect from the wing. We are issuing this 
AD to prevent failure of the eccentric pins at the slat track 
attachment, and slat panels consequently disconnecting from the 
wing, leading to the loss of the airplane.

(f) Compliance

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

[[Page 21389]]

(g) Replacement

    Within 6,000 flight hours or 30 months, whichever occurs first, 
after the effective date of this AD: Remove and replace the locking 
plate having part number (P/N) CC670-12076-1 with an anti-migration 
assembly having P/N CC670-12370-1, on both the left and right number 
3 slats, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 670BA-27-066, dated June 10, 2013.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install any 
locking plate having P/N CC670-12076-1 on any airplane.
