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 ATR—GIE Avions de ´ Transport Regional Model ATR42 and Model ATR72 airplanes. The NPRM published in the Federal Register on September 25, 2013 (78 FR 58967). The NPRM was prompted by reports of defective sealing between the nacelle lower fairing and the underwing box. The NPRM proposed to require a onetime general visual inspection for damaged (worn, torn, or abraded) or missing seals between the nacelle lower fairing and the underwing box of both the left-hand and right-hand engine nacelles, and replacement of the seal and/or shims if necessary. We are issuing this AD to prevent the decrease of the fire extinguishing agent efficiency, which could delay fire extinction and allow fire propagation out of the nacelle fire protected area, resulting in damage to the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, has issued EASA Airworthiness Directive 2012–0160, dated August 24, 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: Some cases of defective sealing have been reported on in-service aeroplanes on LeftHand (LH) and Right-Hand (RH), between the nacelle lower fairing and the underwing box. Investigation results have shown that this issue was due to either damaged or missing seal and/or incorrect adjustment of the nacelle lower fairing. This condition, if not detected and corrected, may decrease the extinguishing agent efficiency, delay the fire extinction and allow fire propagation out of the nacelle fire protected area, possibly resulting in damage to the aeroplane. For the reasons described above, this [EASA] AD requires a one-time [general visual] inspection of the affected area [between the nacelle lower fairing and the underbox wing for damaged (worn, torn, or abraded) or missing seals] and, depending on findings, accomplishment of applicable corrective actions to restore the area integrity. E:\FR\FM\19FER1.SGM 19FER1 9388 Federal Register / Vol. 79, No. 33 / Wednesday, February 19, 2014 / Rules and Regulations Corrective actions include replacing the seal and/or shims. You may examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/ #!documentDetail;D=FAA-2013-07990002. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the NPRM (78 FR 58967, September 25, 2013) 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 (78 FR 58967, September 25, 2013) for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM (78 FR 58967, September 25, 2013). ehiers on DSK2VPTVN1PROD with RULES Costs of Compliance We estimate that this AD affects 42 airplanes of U.S. registry. We also estimate that it will take about 4 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 $0 per product. Based on these figures, we estimate the cost of this AD on U.S. operators to be $14,280, or $340 per product. In addition, we estimate that any necessary follow-on actions will take about 36-work-hours and require parts costing $341, for a cost of $3,401 per product. We have no way of determining the number of aircraft that might need this action. Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting associated with VerDate Mar<15>2010 14:22 Feb 18, 2014 Jkt 232001 this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave., SW., Washington, DC 20591, ATTN: Information Collection Clearance Officer, AES–200. 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 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.

ACTION: Final Rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
ATR--GIE Avions de Transport R[eacute]gional Model ATR42 and Model 
ATR72 airplanes. This AD was prompted by reports of defective sealing 
between the nacelle lower fairing and the underwing box. This AD 
requires a one-time general visual inspection for damaged (worn, torn, 
or abraded) or missing seals between the nacelle lower fairing and the 
underwing box of both the left-hand and right-hand engine nacelles, and 
replacement of the seal and/or shims if necessary. We are issuing this 
AD to prevent the decrease of the fire extinguishing agent efficiency, 
which could delay fire extinction and allow fire propagation out of the 
nacelle fire protected area, resulting in damage to the airplane.

DATES: This AD becomes effective March 26, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of March 26, 
2014.

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 ATR--GIE Avions de 
Transport R[eacute]gional Model ATR42 and Model ATR72 airplanes. The 
NPRM published in the Federal Register on September 25, 2013 (78 FR 
58967). The NPRM was prompted by reports of defective sealing between 
the nacelle lower fairing and the underwing box. The NPRM proposed to 
require a one-time general visual inspection for damaged (worn, torn, 
or abraded) or missing seals between the nacelle lower fairing and the 
underwing box of both the left-hand and right-hand engine nacelles, and 
replacement of the seal and/or shims if necessary. We are issuing this 
AD to prevent the decrease of the fire extinguishing agent efficiency, 
which could delay fire extinction and allow fire propagation out of the 
nacelle fire protected area, resulting in damage to the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0160, dated August 24, 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:

    Some cases of defective sealing have been reported on in-service 
aeroplanes on Left-Hand (LH) and Right-Hand (RH), between the 
nacelle lower fairing and the underwing box.
    Investigation results have shown that this issue was due to 
either damaged or missing seal and/or incorrect adjustment of the 
nacelle lower fairing.
    This condition, if not detected and corrected, may decrease the 
extinguishing agent efficiency, delay the fire extinction and allow 
fire propagation out of the nacelle fire protected area, possibly 
resulting in damage to the aeroplane.
    For the reasons described above, this [EASA] AD requires a one-
time [general visual] inspection of the affected area [between the 
nacelle lower fairing and the underbox wing for damaged (worn, torn, 
or abraded) or missing seals] and, depending on findings, 
accomplishment of applicable corrective actions to restore the area 
integrity.


[[Page 9388]]


    Corrective actions include replacing the seal and/or shims. You may 
examine the MCAI in the AD docket on the Internet at https://www.regulations.gov/#!documentDetail;D=FAA-2013-0799-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 58967, September 
25, 2013) 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 (78 FR 58967, September 25, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 58967, September 25, 2013).

Costs of Compliance

    We estimate that this AD affects 42 airplanes of U.S. registry.
    We also estimate that it will take about 4 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 $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $14,280, or $340 per product.
    In addition, we estimate that any necessary follow-on actions will 
take about 36-work-hours and require parts costing $341, for a cost of 
$3,401 per product. We have no way of determining the number of 
aircraft that might need this action.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for

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 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.

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 AD:

2014-03-09 ATR--GIE Avions de Transport R[eacute]gional: Amendment 
39-17746. Docket No. FAA-2013-0799; Directorate Identifier 2012-NM-
153-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective March 26, 
2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to the airplanes identified in paragraphs (c)(1) 
and (c)(2) of this AD.
    (1) ATR--GIE Avions de Transport R[eacute]gional Model ATR42-
200, -300, -320, and -500 airplanes, certificated in any category, 
manufacturer serial numbers 003 through 623 inclusive.
    (2) ATR--GIE Avions de Transport R[eacute]gional Model ATR72-
101, -201, -102, -202, -211, -212, and -212A airplanes, certificated 
in any category, manufacturer serial numbers 108 through 710 
inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 54, Nacelles/
pylons.

(e) Reason

    This AD was prompted by reports of defective sealing between the 
nacelle lower fairing and the underwing box. We are issuing this AD 
to prevent the decrease of the fire extinguishing agent efficiency, 
which could delay fire extinction and allow fire propagation out of 
the nacelle fire protected area, resulting in damage to the 
airplane.

(f) Compliance

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

(g) Inspection and Corrective Actions

    Within 5,000 flight hours after the effective date of this AD: 
Do a one-time general visual

may be emailed to: 9-ANM-116-AMOC-REQUESTS@faa.gov. Before using any 
approved AMOC, notify your appropriate principal inspector, or 
lacking a principal inspector, the manager of the local flight 
standards district office/certificate holding district office. The 
AMOC approval letter must specifically reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
    (3) Reporting Requirements: A federal agency may not conduct or 
sponsor, and a person is not required to respond to, nor shall a 
person be subject to a penalty for failure to comply with a 
collection of information subject to the requirements of the 
Paperwork Reduction Act unless that collection of information 
displays a current valid OMB Control Number. The OMB Control Number 
for this information collection is 2120-0056. Public reporting for 
this collection of information is estimated to be approximately 5
