SUPPLEMENTARY INFORMATION: Discussion On April 15, 2013, at 78 FR 22213, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to Eurocopter Model EC120B helicopters with a left-hand (LH) emergency flotation gear, part number (P/N) 215674–0, 215674–1, or 215674–2 installed, fitted with a float, P/N 215481–0; or with a right-hand (RH) VerDate Mar<15>2010 16:22 Aug 22, 2013 Jkt 229001 emergency flotation gear, P/N 215675–0, 215675–1, or 215675–2 installed, fitted with a float, P/N 215482–0; and Model EC130B4 helicopters with a LH emergency flotation gear P/N 217227–0 installed, fitted with a float P/N 217174–0; or with a RH emergency flotation gear P/N 217228–0 installed, fitted with a float, P/N 217195–0. The NPRM proposed to require inspecting the float for chafing of the fabric covering and adding protectors to the float installation to prevent contact between the float and the protruding sections of the installation. The proposed requirements were intended to prevent failure of float and subsequent loss of control of the helicopter during an emergency water landing. The NPRM was prompted by AD No. 2011–0185, dated September 23, 2011 (AD 2011–0185), issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD 2011–0185 to correct an unsafe condition for Eurocopter Model EC120 and EC130 helicopters. EASA advises that during overhaul of an emergency flotation gear installation, it was impossible to inflate the RH float according to the instructions in the equipment manufacturer’s manual. An investigation revealed that one of the compartments in the float was punctured and several areas of the LH and RH floats were damaged, caused by chafing between the float and the protruding sections of the supply bars and banjo unions. To address this potentially unsafe condition, EASA issued AD No. 2009–0190, dated August 26, 2009 (AD 2009–0190), which required repetitive inspections of the floats to detect chafing. Aerazur, the float manufacturer, later developed protectors to be installed on the floats to eliminate interference between the float and the blunt parts of the installation. EASA then issued AD 2011–0185, which superseded AD 2009–0190 and required installation of the protectors on the floats as terminating action for the repetitive inspections. 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 Related Service Information Eurocopter has issued Alert Service Bulletin (ASB) No. 05A011, Revision 0, dated June 8, 2009 (ASB 05A011), for Model EC120B helicopters and ASB No. 05A008, Revision 0, dated June 8, 2009 (ASB 05A008), for Model EC130B4 helicopters. Both ASBs specify inspecting the floats for deterioration and chafing at specified intervals and, if necessary, repairing the floats. Eurocopter has also issued ASB No. EC120–25A026, Revision 0, dated July 11, 2011 (ASB EC120–25A026), for Model EC120B helicopters and ASB No. EC130–25A042, Revision 0, dated July 11, 2011 (ASB EC130–25A042), for Model EC130B4 helicopters. Both ASBs specify modifying certain partnumbered LH and RH emergency flotation gear by adding protectors onto the rear bracket and supply couplings of the float installation. The ASBs specify following procedures in Aerazur Service Bulletin (SB) No. 25–69–87, dated March 14, 2011, for floats installed on Model EC120B helicopters and Aerazur SB No. 25–69–58, dated March 14, 2011, for floats installed on Model EC130B4 helicopters. Each Aerazur SB is incorporated as an appendix to the corresponding Eurocopter ASB. 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 22213, April 15, 2013). Costs of Compliance We estimate that this AD will affect 60 helicopters of U.S. Registry. Based on an average labor rate of $85 per workhour, we estimate that operators may incur the following costs to comply with this AD. Inspecting the floats for chafing will require about .5 hour, for a cost per helicopter of $43, and a cost to U.S. operators of $2,580. Modifying the floats with protective covers will require about 1 hour and required parts cost about $500, for a cost per helicopter of $585, and a cost to U.S. operators of $35,100. The total estimated cost of this AD is $628 per helicopter and $37,680 for the U.S. operator fleet. 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 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 PO 00000 Frm 00020 Fmt 4700 Sfmt 4700 E:\FR\FM\23AUR1.SGM 23AUR1 Federal Register / Vol. 78, No. 164 / Friday, August 23, 2013 / Rules and Regulations 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.

SUPPLEMENTARY INFORMATION: Discussion On August 29, 2012, at 77 FR 52265, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 to include an AD that would apply to ECD Model BO–105A, BO–105C, BO– 105S, BO–105LS A–1, BO–105LS A–3, MBB–BK 117 A–1, MBB–BK 117 A–3, PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 MBB–BK 117 A–4, MBB–BK117 B–1, MBB–BK 117 B–2, and MBB–BK 117 C– 1 helicopters with certain levers and weights installed. The NPRM proposed to require conducting repetitive visual inspections of each weight and lever and proposed procedures for installing a weight or lever. Additionally, the NPRM proposed allowable tolerances for corrosion or thread damage on the threaded portion of a weight or lever and proposed to require that a part with corrosion or mechanical damage in excess of allowable tolerances be replaced with an airworthy part. The proposed requirements were intended to detect corrosion and thread damage in the threaded area of a weight or lever, to prevent failure of a weight or lever, separation of tail rotor parts, severe vibration, and subsequent loss of control of the helicopter. The NPRM was prompted by AD No. 2008–0206, dated November 25, 2008, issued by EASA, which is the Technical Agent for the Member States of the European Union, and AD No. CF–2009– 12, dated March 24, 2009, issued by the TCCA, which is the aviation authority for Canada. EASA issued AD No. 2008– 0206 to correct the unsafe condition for ECD Model BO 105 A, BO 105 C, BO 105 LS A–1, BO 105 D, BO 105 DS, BO 105 DB, BO 105 DBS, BO 105 DB–4, BO 105 DBS–4, BO 105 DBS–5, BO 105 S, MBB–BK 117 A–1, MBB–BK 117 A–3, MBB–BK 117 A–4, MBB–BK 117 B–1, MBB–BK 117 B–2, and MBB–BK 117 C– 1 helicopters. The TCCA issued AD No. CF–2009–12 to correct the unsafe condition for Eurocopter Model BO 105 LS A–3 helicopters. These ADs state that during a periodical inspection, corrosion was detected on the weights in the area of the attachment thread. Since the issuance of the Canadian AD, the type certificate for the Model BO 105 LS A–3 has been transferred from Eurocopter Canada Limited to Eurocopter Deutschland (Germany). Comments We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM (77 FR 52265, August 29, 2012). FAA’s Determination These helicopters have been approved by the aviation authority of Germany and are approved for operation in the United States. Pursuant to our bilateral agreement with Germany, 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 E:\FR\FM\23AUR1.SGM 23AUR1

SUPPLEMENTARY INFORMATION: 

Discussion

    On April 15, 2013, at 78 FR 22213, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 to include an AD that would apply to Eurocopter Model 
EC120B helicopters with a left-hand (LH) emergency flotation gear, part 
number (P/N) 215674-0, 215674-1, or 215674-2 installed, fitted with a 
float, P/N 215481-0; or with a right-hand (RH) emergency flotation 
gear, P/N 215675-0, 215675-1, or 215675-2 installed, fitted with a 
float, P/N 215482-0; and Model EC130B4 helicopters with a LH emergency 
flotation gear P/N 217227-0 installed, fitted with a float P/N 217174-
0; or with a RH emergency flotation gear P/N 217228-0 installed, fitted 
with a float, P/N 217195-0. The NPRM proposed to require inspecting the 
float for chafing of the fabric covering and adding protectors to the 
float installation to prevent contact between the float and the 
protruding sections of the installation. The proposed requirements were 
intended to prevent failure of float and subsequent loss of control of 
the helicopter during an emergency water landing.
    The NPRM was prompted by AD No. 2011-0185, dated September 23, 2011 
(AD 2011-0185), issued by the European Aviation Safety Agency (EASA), 
which is the Technical Agent for the Member States of the European 
Union. EASA issued AD 2011-0185 to correct an unsafe condition for 
Eurocopter Model EC120 and EC130 helicopters. EASA advises that during 
overhaul of an emergency flotation gear installation, it was impossible 
to inflate the RH float according to the instructions in the equipment 
manufacturer's manual. An investigation revealed that one of the 
compartments in the float was punctured and several areas of the LH and 
RH floats were damaged, caused by chafing between the float and the 
protruding sections of the supply bars and banjo unions. To address 
this potentially unsafe condition, EASA issued AD No. 2009-0190, dated 
August 26, 2009 (AD 2009-0190), which required repetitive inspections 
of the floats to detect chafing. Aerazur, the float manufacturer, later 
developed protectors to be installed on the floats to eliminate 
interference between the float and the blunt parts of the installation. 
EASA then issued AD 2011-0185, which superseded AD 2009-0190 and 
required installation of the protectors on the floats as terminating 
action for the repetitive inspections.

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 22213, 
April 15, 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

Related Service Information

    Eurocopter has issued Alert Service Bulletin (ASB) No. 05A011, 
Revision 0, dated June 8, 2009 (ASB 05A011), for Model EC120B 
helicopters and ASB No. 05A008, Revision 0, dated June 8, 2009 (ASB 
05A008), for Model EC130B4 helicopters. Both ASBs specify inspecting 
the floats for deterioration and chafing at specified intervals and, if 
necessary, repairing the floats.
    Eurocopter has also issued ASB No. EC120-25A026, Revision 0, dated 
July 11, 2011 (ASB EC120-25A026), for Model EC120B helicopters and ASB 
No. EC130-25A042, Revision 0, dated July 11, 2011 (ASB EC130-25A042), 
for Model EC130B4 helicopters. Both ASBs specify modifying certain 
part-numbered LH and RH emergency flotation gear by adding protectors 
onto the rear bracket and supply couplings of the float installation. 
The ASBs specify following procedures in Aerazur Service Bulletin (SB) 
No. 25-69-87, dated March 14, 2011, for floats installed on Model 
EC120B helicopters and Aerazur SB No. 25-69-58, dated March 14, 2011, 
for floats installed on Model EC130B4 helicopters. Each Aerazur SB is 
incorporated as an appendix to the corresponding Eurocopter ASB.

Costs of Compliance

    We estimate that this AD will affect 60 helicopters of U.S. 
Registry. Based on an average labor rate of $85 per work-hour, we 
estimate that operators may incur the following costs to comply with 
this AD. Inspecting the floats for chafing will require about .5 hour, 
for a cost per helicopter of $43, and a cost to U.S. operators of 
$2,580. Modifying the floats with protective covers will require about 
1 hour and required parts cost about $500, for a cost per helicopter of 
$585, and a cost to U.S. operators of $35,100. The total estimated cost 
of this AD is $628 per helicopter and $37,680 for the U.S. operator 
fleet.

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

[[Page 52409]]

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.
