SUPPLEMENTARY INFORMATION: Discussion On April 15, 2013, at 78 FR 22209, 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 Eurocopter Model EC135 P1, EC135 P2, EC135 P2+, EC135 T1, EC135 T2 and EC135 T2+ helicopters with a Goodrich Corporation (Goodrich) hoist with a boom, Part Number (P/N) 44301–500, 44307–500, or 44307–500–1 installed, and Model MBB–BK 117 C–2 helicopters with a Goodrich hoist with boom P/N 44307–500 installed. The NPRM proposed to require dye penetrant inspecting the boom for a crack and, if a crack exists, replacing the boom with an airworthy boom. Until the inspection is completed, the NPRM proposed to require, before the first flight of each day, a visual check of the hoist for a crack. The NPRM proposed to allow an owner/operator (pilot) holding at least a private pilot certificate to conduct that check. The performance of the check would be required to be entered into the aircraft’s maintenance records showing compliance with this AD in accordance with applicable regulations. This authorization marks an exception to our standard maintenance regulations. The proposed requirements were intended to detect a crack and prevent failure of the boom, loss of the PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 boom and attached loads, and subsequent loss of helicopter control. The NPRM was prompted by AD No. 2010–0154, dated August 13, 2010, issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA issued AD No. 2010–0154 to correct an unsafe condition for Eurocopter Model MBB– BK 117 C–2, EC135, and EC635 series helicopters. EASA AD No. 2010–0154 supersedes EASA AD No. 2009–0093–E, dated April 17, 2009. EASA advises that cracks were detected on the boom, P/N 44307–500, during a pre-flight check of the hoist on a Model MBB–BK 117 C– 2 helicopter. EASA advises that this condition, if not detected and corrected, would impair the structural strength of the boom and could lead to failure of the boom. EASA advises that this could result in the loss of the boom and attached loads. According to EASA, boom P/Ns 44301–500 and 44307–500– 1 are of similar design to P/N 44307– 500, and therefore are also subject to this unsafe condition. As a result, EASA issued Emergency AD No. 2009–0093–E to require repetitive visual checks of the affected boom and removal or replacement of the boom when cracks are found. EASA advises that since AD No. 2009–0093–E was issued, further technical investigation determined that torque values that were too high have been applied. EASA advises that Goodrich Corporation, the manufacturer of the affected booms, had developed an inspection that would determine the need for further action. As a result, EASA superseded its AD to include a new inspection to detect damage, by issuing EASA AD No. 2010–0154. EASA AD states that if no damage is found during this new inspection, that constitutes terminating action. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM (78 FR 22209, April 15, 2013). 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 exist or develop on other helicopters of these same type designs and that air E:\FR\FM\27DER1.SGM 27DER1 Federal Register / Vol. 78, No. 249 / Friday, December 27, 2013 / Rules and Regulations safety and the public interest require adopting the AD requirements as proposed. Differences Between This AD and the EASA AD The EASA AD requires you to notify and return parts to the manufacturer, and this AD does not. The EASA AD also applies to the Eurocopter EC635 series military helicopters, while this AD does not because these models are not type certificated in the United States. Related Service Information Eurocopter has issued Emergency Alert Service Bulletin (EASB) No. EC135–85A–036, Revision 2, dated June 23, 2010, and EASB No. MBB BK117 C– 2–85A–024, Revision 1, dated June 23, 2010, which specify a visual check of the boom for cracks, and removing or replacing the boom before the next flight if there is a crack. The EASBs also require compliance with the visual and dye penetrant inspection procedures specified in Goodrich Corporation Service Bulletin 44307–500–03, Revision 2, dated April 30, 2010. EASA classified these EASBs as mandatory, and issued EASA AD No. 2010–0154, dated August 13, 2010, to ensure the continued airworthiness of these helicopters. Costs of Compliance We estimate that this AD affects 350 helicopters of U.S. Registry and a labor rate of $85 per work-hour. Based on these estimates, we expect the following costs: • We estimate that the cost of the daily visual check is minimal. • We estimate that removing the hoist and boom assembly, performing the dye penetrant inspection, and reinstalling the equipment requires 1.5 work hours. No parts are needed, for a total cost of about $128 per helicopter and $44,800 for the U.S. fleet. • Replacing the hoist and boom assembly, if needed, requires about a 0.33 work-hour for a labor cost of about $28. Parts cost $10,833 for a total cost of $10,861 per helicopter. Authority for This Rulemaking tkelley on DSK3SPTVN1PROD with RULES Title 49 of the United States Code specifies the FAA’s authority to issue VerDate Mar<15>2010 18:49 Dec 26, 2013 Jkt 232001 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    On April 15, 2013, at 78 FR 22209, 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 Eurocopter Model EC135 
P1, EC135 P2, EC135 P2+, EC135 T1, EC135 T2 and EC135 T2+ helicopters 
with a Goodrich Corporation (Goodrich) hoist with a boom, Part Number 
(P/N) 44301-500, 44307-500, or 44307-500-1 installed, and Model MBB-BK 
117 C-2 helicopters with a Goodrich hoist with boom P/N 44307-500 
installed. The NPRM proposed to require dye penetrant inspecting the 
boom for a crack and, if a crack exists, replacing the boom with an 
airworthy boom. Until the inspection is completed, the NPRM proposed to 
require, before the first flight of each day, a visual check of the 
hoist for a crack. The NPRM proposed to allow an owner/operator (pilot) 
holding at least a private pilot certificate to conduct that check. The 
performance of the check would be required to be entered into the 
aircraft's maintenance records showing compliance with this AD in 
accordance with applicable regulations. This authorization marks an 
exception to our standard maintenance regulations. The proposed 
requirements were intended to detect a crack and prevent failure of the 
boom, loss of the boom and attached loads, and subsequent loss of 
helicopter control.
    The NPRM was prompted by AD No. 2010-0154, dated August 13, 2010, 
issued by the European Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union. EASA 
issued AD No. 2010-0154 to correct an unsafe condition for Eurocopter 
Model MBB-BK 117 C-2, EC135, and EC635 series helicopters. EASA AD No. 
2010-0154 supersedes EASA AD No. 2009-0093-E, dated April 17, 2009. 
EASA advises that cracks were detected on the boom, P/N 44307-500, 
during a pre-flight check of the hoist on a Model MBB-BK 117 C-2 
helicopter. EASA advises that this condition, if not detected and 
corrected, would impair the structural strength of the boom and could 
lead to failure of the boom. EASA advises that this could result in the 
loss of the boom and attached loads. According to EASA, boom P/Ns 
44301-500 and 44307-500-1 are of similar design to P/N 44307-500, and 
therefore are also subject to this unsafe condition. As a result, EASA 
issued Emergency AD No. 2009-0093-E to require repetitive visual checks 
of the affected boom and removal or replacement of the boom when cracks 
are found.
    EASA advises that since AD No. 2009-0093-E was issued, further 
technical investigation determined that torque values that were too 
high have been applied. EASA advises that Goodrich Corporation, the 
manufacturer of the affected booms, had developed an inspection that 
would determine the need for further action. As a result, EASA 
superseded its AD to include a new inspection to detect damage, by 
issuing EASA AD No. 2010-0154. EASA AD states that if no damage is 
found during this new inspection, that constitutes terminating action.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (78 FR 22209, April 
15, 2013).

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 exist or develop on other helicopters of these same 
type designs and that air

[[Page 78711]]

safety and the public interest require adopting the AD requirements as 
proposed.

Differences Between This AD and the EASA AD

    The EASA AD requires you to notify and return parts to the 
manufacturer, and this AD does not. The EASA AD also applies to the 
Eurocopter EC635 series military helicopters, while this AD does not 
because these models are not type certificated in the United States.

Related Service Information

    Eurocopter has issued Emergency Alert Service Bulletin (EASB) No. 
EC135-85A-036, Revision 2, dated June 23, 2010, and EASB No. MBB BK117 
C-2-85A-024, Revision 1, dated June 23, 2010, which specify a visual 
check of the boom for cracks, and removing or replacing the boom before 
the next flight if there is a crack. The EASBs also require compliance 
with the visual and dye penetrant inspection procedures specified in 
Goodrich Corporation Service Bulletin 44307-500-03, Revision 2, dated 
April 30, 2010. EASA classified these EASBs as mandatory, and issued 
EASA AD No. 2010-0154, dated August 13, 2010, to ensure the continued 
airworthiness of these helicopters.

Costs of Compliance

    We estimate that this AD affects 350 helicopters of U.S. Registry 
and a labor rate of $85 per work-hour. Based on these estimates, we 
expect the following costs:
     We estimate that the cost of the daily visual check is 
minimal.
     We estimate that removing the hoist and boom assembly, 
performing the dye penetrant inspection, and reinstalling the equipment 
requires 1.5 work hours. No parts are needed, for a total cost of about 
$128 per helicopter and $44,800 for the U.S. fleet.
     Replacing the hoist and boom assembly, if needed, requires 
about a 0.33 work-hour for a labor cost of about $28. Parts cost 
$10,833 for a total cost of $10,861 per helicopter.

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.
