SUPPLEMENTARY INFORMATION: Discussion On July 23, 2013, at 78 FR 44050, 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 EC135P2+ and EC135T2+ helicopters, serial numbers 870, 872, 873, 879, 883, 884, 888, 893, 900, 905, 911, 914, 916, 917, 923, and 926, with an upper bearing, part number (P/N) L210M1872105, installed. The NPRM proposed to require inspecting the upper bearing for corrosion, leaking grease, condensation, or water. The proposed requirements were intended to prevent metallic debris from damaging the engine, causing loss of engine power, and subsequent loss of helicopter control. The NPRM was prompted by AD No. 2011–0111R1, dated September 22, 2011, issued by the European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union. EASA AD No. 2011–0111R1 revises EASA AD No. 2011–0111, dated June 10, 2011, to correct an unsafe condition for certain Model EC135P2+ and EC135T2+ PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 helicopters. EASA advises that metallic debris was found within the air inlet area of both engines during a pre-flight check of an EC135 P2+ helicopter. A subsequent investigation showed that the debris came from the bearing cage of a ball bearing in the air conditioning compressor bearing block, and that it damaged the compressor stage of one of the engines to such an extent that the engine had to be overhauled, according to EASA. EASA notes that as this mechanical air conditioning system was introduced recently on the production line, only a limited number of helicopters are affected. But if not detected and corrected, this unsafe condition ‘‘could lead to further cases of bearing case failure, possibly resulting in loss of engine power and reduced control of the helicopter,’’ EASA reports. EASA AD No. 2011–0111R1 requires repetitive inspections of the affected ball bearing for indications that the upper bearing is failing and, depending on the findings, deactivating the air conditioning system. Comments We gave the public the opportunity to participate in developing this AD, but we received no comments on the NPRM (78 FR 44050, July 23, 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 safety and the public interest require adopting the AD requirements as proposed. Related Service Information Eurocopter issued Emergency Alert Service Bulletin (EASB) EC135–21A– 013, Revision 0, dated June 6, 2011, to provide instructions for inspections after debris from the bearing cage of a ball bearing was found in the air inlet area of both engines of an EC135P2+ helicopter.

We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket. in accordance with the Accomplishment Instructions, Section 3.B.3, Paragraphs (a) through (ai) of Eurocopter Emergency Alert Service Bulletin No. EC135–21A–013, Revision 0, dated June 6, 2011. Costs of Compliance List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. (f) Alternative Methods of Compliance (AMOCs) We estimate that this AD affects 1 helicopter of U.S. Registry and that labor costs average $85 per work-hour. Based on these estimates, we expect the following costs: • Inspecting the upper bearing for corrosion, leaking grease, condensation or water requires 4 work-hours for a labor cost of $340. No parts are needed. • Deactivating the air conditioning system requires 6 work-hours for a labor cost of $510. No parts are needed. 1. The authority citation for part 39 continues to read as follows: 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. pmangrum on DSK3VPTVN1PROD with RULES Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

SUPPLEMENTARY INFORMATION: 

Discussion

    On July 23, 2013, at 78 FR 44050, 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 
EC135P2+ and EC135T2+ helicopters, serial numbers 870, 872, 873, 879, 
883, 884, 888, 893, 900, 905, 911, 914, 916, 917, 923, and 926, with an 
upper bearing, part number (P/N) L210M1872105, installed.
    The NPRM proposed to require inspecting the upper bearing for 
corrosion, leaking grease, condensation, or water. The proposed 
requirements were intended to prevent metallic debris from damaging the 
engine, causing loss of engine power, and subsequent loss of helicopter 
control.
    The NPRM was prompted by AD No. 2011-0111R1, dated September 22, 
2011, issued by the European Aviation Safety Agency (EASA), which is 
the Technical Agent for the Member States of the European Union. EASA 
AD No. 2011-0111R1 revises EASA AD No. 2011-0111, dated June 10, 2011, 
to correct an unsafe condition for certain Model EC135P2+ and EC135T2+ 
helicopters. EASA advises that metallic debris was found within the air 
inlet area of both engines during a pre-flight check of an EC135 P2+ 
helicopter. A subsequent investigation showed that the debris came from 
the bearing cage of a ball bearing in the air conditioning compressor 
bearing block, and that it damaged the compressor stage of one of the 
engines to such an extent that the engine had to be overhauled, 
according to EASA.
    EASA notes that as this mechanical air conditioning system was 
introduced recently on the production line, only a limited number of 
helicopters are affected. But if not detected and corrected, this 
unsafe condition ``could lead to further cases of bearing case failure, 
possibly resulting in loss of engine power and reduced control of the 
helicopter,'' EASA reports. EASA AD No. 2011-0111R1 requires repetitive 
inspections of the affected ball bearing for indications that the upper 
bearing is failing and, depending on the findings, deactivating the air 
conditioning system.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we received no comments on the NPRM (78 FR 44050, July 23, 
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 safety and the public interest require 
adopting the AD requirements as proposed.

Related Service Information

    Eurocopter issued Emergency Alert Service Bulletin (EASB) EC135-
21A-013, Revision 0, dated June 6, 2011, to provide instructions for 
inspections after debris from the bearing cage of a ball bearing was 
found in the air inlet area of both engines of an EC135P2+ helicopter. 
Eurocopter followed the EASB with Service Bulletin EC135-21-

[[Page 4268]]

015, Revision 0, dated July 12, 2011, to introduce the replacement of 
the affected compressor bearing block with a ``new, improved'' 
compressor bearing block.

Costs of Compliance

    We estimate that this AD affects 1 helicopter of U.S. Registry and 
that labor costs average $85 per work-hour. Based on these estimates, 
we expect the following costs:
     Inspecting the upper bearing for corrosion, leaking 
grease, condensation or water requires 4 work-hours for a labor cost of 
$340. No parts are needed.
     Deactivating the air conditioning system requires 6 work-
hours for a labor cost of $510. No parts are needed.

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.
