Sfmt 4700 SUPPLEMENTARY INFORMATION: Discussion On July 3, 2013 at 78 FR 40072, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to certain serial-numbered Eurocopter (now Airbus Helicopters) Model AS332C1 and AS332L1 helicopters. The NPRM proposed to require replacing the non-conforming 3.2 mm rivets, partnumber (P/N) 212 15DC 3200J, on the longitudinal beams Y350 with airworthy 4.8 mm rivets, P/N 212 15DC 4800J. The proposed requirements were intended to prevent failure of the longitudinal beams Y350 and subsequent loss of control of the helicopter. The NPRM was prompted by AD No. 2012–0046–E, dated March 21, 2012 (EAD 2012–0046–E), issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Model AS332C1 and AS332L1 helicopters. EASA advises that an AS332 helicopter was found on the production line with non-conforming rivets installed on the RH and LH longitudinal beams Y350 of the bottom structure of the fuselage, between sections X4780 and X5295. According to EASA, the investigation revealed that a limited number of helicopters were documented as receiving a production modification requiring the replacement of certain 3.2 mm rivets with 4.8 mm rivets, but the actual replacement of the rivets had not been performed. EASA states that this condition leads to significant reduction in the safety margins during sling operations and may cause failure of the web/flange assembly connections of the longitudinal beams Y350, possibly resulting in loss of control of the helicopter. For these reasons, EASA issued EAD 2012–0046–E, which, pending inspection of the helicopter beams Y350 and replacement of the affected rivets, prohibits sling operations or limits the 3-ton sling to external loads of 2.28 tons or less. E:\FR\FM\11MRR1.SGM 11MRR1 Federal Register / Vol. 79, No. 47 / Tuesday, March 11, 2014 / Rules and Regulations Since the NPRM was published, we have determined that the applicability requirements of the proposed AD should not apply to Model AS332C1 helicopters, because that model is not type certificated in the United States. We have removed that model and its corresponding serial numbers from this AD. Also, Eurocopter France has changed its name to Airbus Helicopters. This AD reflects that change and updates to contact information to obtain service information. Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (78 FR 40072, July 3, 2013). mstockstill on DSK4VPTVN1PROD with RULES FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed, except that we have removed Eurocopter Model AS332C1 helicopters from the Applicability paragraph and changed Eurocopter France to Airbus Helicopters. These changes are consistent with the intent of the proposals in the NPRM (78 FR 40072, July 3, 2013) and will not increase the economic burden on any operator nor increase the scope of the AD. Differences Between This AD and the EASA AD The EASA AD requires limiting the use of the 3-ton sling, inspecting the longitudinal beams Y350 for loose or missing rivets, black marks around the rivets, and cracks, and, depending on the accumulated sling operation cycles, replacing the rivets within a period of up to 24 months. This AD does not require the inspections as it would require replacing the rivets within 10 hours time-in-service, regardless of accumulated sling operation cycles. The EASA AD applies to Model AS332C1 helicopters, and this AD does not because that model is not type certificated in the United States. Related Service Information We reviewed Eurocopter Emergency Alert Service Bulletin No. 01.00.81 VerDate Mar<15>2010 16:00 Mar 10, 2014 Jkt 232001 Revision 0, dated March 19, 2012 (EASB 01.00.81) for Model AS332 helicopters. The EASB describes procedures for temporarily prohibiting sling operations or limiting the use of the 3-ton sling to 2.28 tons until the 3.2 mm diameter rivets are replaced with 4.8 mm diameter rivets. We have subsequently reviewed Eurocopter EASB 01.00.81 Revision 1, dated July 6, 2012 (EASB 01.00.81 Revision 1). EASB 01.00.81 Revision 1 deletes from the applicability of the EASB helicopters with Modification (MOD) 07 26082 installed. MOD 07 26082 provides for installation of the correct 4.8 mm diameter rivets on Eurocopter’s production line. Costs of Compliance We estimate that this AD will affect 1 helicopter of U.S. Registry. We estimate that operators will incur the following costs in order to comply with this AD. Modifying the longitudinal beams Y350 with 4.8 mm rivets requires about 24 work-hours at an average labor rate of $85 per hour and required parts cost about $110, for a total cost per helicopter of $2,150. Thus, the total cost to U.S. operators to comply with this AD is about $2,150. 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 helicopters identified in this rulemaking action. Regulatory Findings 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. PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 13525 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 DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); (3) Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

SUPPLEMENTARY INFORMATION:

Discussion

    On July 3, 2013 at 78 FR 40072, the Federal Register published our 
notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR 
part 39 by adding an AD that would apply to certain serial-numbered 
Eurocopter (now Airbus Helicopters) Model AS332C1 and AS332L1 
helicopters. The NPRM proposed to require replacing the non-conforming 
3.2 mm rivets, part-number (P/N) 212 15DC 3200J, on the longitudinal 
beams Y350 with airworthy 4.8 mm rivets, P/N 212 15DC 4800J. The 
proposed requirements were intended to prevent failure of the 
longitudinal beams Y350 and subsequent loss of control of the 
helicopter.
    The NPRM was prompted by AD No. 2012-0046-E, dated March 21, 2012 
(EAD 2012-0046-E), issued by the European Aviation Safety Agency 
(EASA), which is the Technical Agent for the Member States of the 
European Union, to correct an unsafe condition for Model AS332C1 and 
AS332L1 helicopters. EASA advises that an AS332 helicopter was found on 
the production line with non-conforming rivets installed on the RH and 
LH longitudinal beams Y350 of the bottom structure of the fuselage, 
between sections X4780 and X5295. According to EASA, the investigation 
revealed that a limited number of helicopters were documented as 
receiving a production modification requiring the replacement of 
certain 3.2 mm rivets with 4.8 mm rivets, but the actual replacement of 
the rivets had not been performed. EASA states that this condition 
leads to significant reduction in the safety margins during sling 
operations and may cause failure of the web/flange assembly connections 
of the longitudinal beams Y350, possibly resulting in loss of control 
of the helicopter. For these reasons, EASA issued EAD 2012-0046-E, 
which, pending inspection of the helicopter beams Y350 and replacement 
of the affected rivets, prohibits sling operations or limits the 3-ton 
sling to external loads of 2.28 tons or less.

[[Page 13525]]

    Since the NPRM was published, we have determined that the 
applicability requirements of the proposed AD should not apply to Model 
AS332C1 helicopters, because that model is not type certificated in the 
United States. We have removed that model and its corresponding serial 
numbers from this AD. Also, Eurocopter France has changed its name to 
Airbus Helicopters. This AD reflects that change and updates to contact 
information to obtain service information.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM (78 FR 40072, 
July 3, 2013).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs and that air safety and the public interest require 
adopting the AD requirements as proposed, except that we have removed 
Eurocopter Model AS332C1 helicopters from the Applicability paragraph 
and changed Eurocopter France to Airbus Helicopters. These changes are 
consistent with the intent of the proposals in the NPRM (78 FR 40072, 
July 3, 2013) and will not increase the economic burden on any operator 
nor increase the scope of the AD.

Differences Between This AD and the EASA AD

    The EASA AD requires limiting the use of the 3-ton sling, 
inspecting the longitudinal beams Y350 for loose or missing rivets, 
black marks around the rivets, and cracks, and, depending on the 
accumulated sling operation cycles, replacing the rivets within a 
period of up to 24 months. This AD does not require the inspections as 
it would require replacing the rivets within 10 hours time-in-service, 
regardless of accumulated sling operation cycles. The EASA AD applies 
to Model AS332C1 helicopters, and this AD does not because that model 
is not type certificated in the United States.

Related Service Information

    We reviewed Eurocopter Emergency Alert Service Bulletin No. 
01.00.81 Revision 0, dated March 19, 2012 (EASB 01.00.81) for Model 
AS332 helicopters. The EASB describes procedures for temporarily 
prohibiting sling operations or limiting the use of the 3-ton sling to 
2.28 tons until the 3.2 mm diameter rivets are replaced with 4.8 mm 
diameter rivets.
    We have subsequently reviewed Eurocopter EASB 01.00.81 Revision 1, 
dated July 6, 2012 (EASB 01.00.81 Revision 1). EASB 01.00.81 Revision 1 
deletes from the applicability of the EASB helicopters with 
Modification (MOD) 07 26082 installed. MOD 07 26082 provides for 
installation of the correct 4.8 mm diameter rivets on Eurocopter's 
production line.

Costs of Compliance

    We estimate that this AD will affect 1 helicopter of U.S. Registry. 
We estimate that operators will incur the following costs in order to 
comply with this AD. Modifying the longitudinal beams Y350 with 4.8 mm 
rivets requires about 24 work-hours at an average labor rate of $85 per 
hour and required parts cost about $110, for a total cost per 
helicopter of $2,150. Thus, the total cost to U.S. operators to comply 
with this AD is about $2,150.

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 helicopters identified in this 
rulemaking action.

Regulatory Findings

    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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    (3) Will not affect intrastate aviation in Alaska to the extent 
that it justifies making a regulatory distinction; 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 an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
