We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2006– 0318 R1, dated October 27, 2006, to correct an unsafe condition for all Eurocopter Model EC 135 helicopters. VerDate Mar<15>2010 17:52 May 22, 2013 Jkt 229001 EASA advises of an incident in which impaired control of an EC 135 tail rotor was detected. EASA states that according to examinations, the bearing of the linear transducer was subject to binding, which limited the control range. 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 its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Eurocopter has issued Alert Service Bulletin EC135–67A–012, Revision 1, dated October 18, 2006 (ASB), which specifies inspecting the bearing of the linear transducer for freedom of movement and the lower side of the floor for chafing or damage. If there is binding, the ASB specifies replacing the bearing. If there is chafing or damage on the floor, the ASB specifies replacing the bearing and repairing the floor. The ASB also specifies modifying and reidentifying a certain rod. EASA classified this ASB as mandatory and issued EASA AD 2006–0318 R1, dated October 27, 2006, to ensure the continued airworthiness of these helicopters. Proposed AD Requirements This proposed AD would require, at specified intervals, inspecting each bearing for freedom of movement. If there is binding or rough turning, this proposed AD would require, before further flight, replacing the bearing or if there is chafing or damage on the lower side of the floor, replacing the bearing and repairing the floor, and, thereafter, installing a Teflon strip. This proposed AD would also require modifying the rod and re-identifying the rod and lever with a new part number. Differences Between This Proposed AD and the EASA AD This proposed AD does not refer to the compliance date of October 31, 2006, because that date has passed; instead we propose compliance within 100 hours TIS. The proposed AD would not require contacting Eurocopter customer support. This proposed AD would require modifying each rod within 100 hours TIS, rather than PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 within 800 hours TIS as specified in the EASA AD. Costs of Compliance We estimate that this proposed AD would affect 214 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD: It would take about 10 work-hours to inspect the bearing for freedom of movement at an average labor rate of $85 per work hour. No parts or materials are required for the inspection. Based on these estimates, the cost would be $850 per helicopter or $181,900 for the fleet of all U.S.-registered helicopters. If necessary, replacing the bearing would require 3 additional work-hours, and parts would cost $50. Repairing the floor would require 3 additional work hours and minimal cost for materials. 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation: 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 to the extent that it justifies making a regulatory distinction; and E:\FR\FM\23MYP1.SGM 23MYP1 Federal Register / Vol. 78, No. 100 / Thursday, May 23, 2013 / Proposed Rules 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 proposed AD and placed it in the AD docket.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
Eurocopter Deutschland GmbH (Eurocopter) Model EC135 P1, P2, P2+, T1, 
T2, and T2+ helicopters to require inspecting each linear transducer 
bearing (bearing) for freedom of movement. This proposed AD would also 
require replacing the bearing if there is binding or rough turning or 
if there is chafing or damage on the lower side of the floor. Also, 
this proposed AD would require modifying and re-identifying a certain 
rod. This proposed AD is prompted by an incident involving limited 
control of a tail rotor because of the binding of a bearing. The 
proposed actions are intended to detect and replace each bearing 
subject to binding, which could lead to subsequent loss of control of 
the helicopter.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2006-0318 R1, dated October 27, 2006, to correct an unsafe 
condition for all Eurocopter Model EC 135 helicopters. EASA advises of 
an incident in which impaired control of an EC 135 tail rotor was 
detected. EASA states that according to examinations, the bearing of 
the linear transducer was subject to binding, which limited the control 
range.

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 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition exists and 
is likely to exist or develop on other helicopters of these same type 
designs.

Related Service Information

    Eurocopter has issued Alert Service Bulletin EC135-67A-012, 
Revision 1, dated October 18, 2006 (ASB), which specifies inspecting 
the bearing of the linear transducer for freedom of movement and the 
lower side of the floor for chafing or damage. If there is binding, the 
ASB specifies replacing the bearing. If there is chafing or damage on 
the floor, the ASB specifies replacing the bearing and repairing the 
floor. The ASB also specifies modifying and reidentifying a certain 
rod. EASA classified this ASB as mandatory and issued EASA AD 2006-0318 
R1, dated October 27, 2006, to ensure the continued airworthiness of 
these helicopters.

    This proposed AD would require, at specified intervals, inspecting 
each bearing for freedom of movement. If there is binding or rough 
turning, this proposed AD would require, before further flight, 
replacing the bearing or if there is chafing or damage on the lower 
side of the floor, replacing the bearing and repairing the floor, and, 
thereafter, installing a Teflon strip. This proposed AD would also 
require modifying the rod and re-identifying the rod and lever with a 
new part number.

Differences Between This Proposed AD and the EASA AD

    This proposed AD does not refer to the compliance date of October 
31, 2006, because that date has passed; instead we propose compliance 
within 100 hours TIS. The proposed AD would not require contacting 
Eurocopter customer support. This proposed AD would require modifying 
each rod within 100 hours TIS, rather than within 800 hours TIS as 
specified in the EASA AD.

Costs of Compliance

    We estimate that this proposed AD would affect 214 helicopters of 
U.S. Registry. We estimate that operators may incur the following costs 
in order to comply with this AD: It would take about 10 work-hours to 
inspect the bearing for freedom of movement at an average labor rate of 
$85 per work hour. No parts or materials are required for the 
inspection. Based on these estimates, the cost would be $850 per 
helicopter or $181,900 for the fleet of all U.S.-registered 
helicopters. If necessary, replacing the bearing would require 3 
additional work-hours, and parts would cost $50. Repairing the floor 
would require 3 additional work hours and minimal cost for materials.

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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, I certify this proposed regulation:
    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 to the extent that 
it justifies making a regulatory distinction; and

[[Page 30795]]

    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 proposed AD and placed it in the AD docket.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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]

2. The FAA amends Sec.  39.13 by adding the following new Airworthiness 
Directive (AD):

Eurocopter Deutschland GmbH: Docket No. FAA-2013-0446; Directorate 
Identifier 2010-SW-007-AD.

(a) Applicability

    This AD applies to Model EC135 P1, P2, P2+, T1, T2, and T2+ 
helicopters, with bearing, part number (P/N) LN9367GE6N2; rod, P/N 
L671M5040205; lever, P/N L671M5040101; and floor, P/N L533M1014101, 
L533M1014102, L533M1014103, L533M1014104, L533M1014105 or 
L533M1014106, installed, certificated in any category.

(b) Unsafe Condition

    This AD defines the unsafe condition as limited control of a 
tail rotor because of the binding of a bearing. This condition could 
result in subsequent loss of control of the helicopter.

(c) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(d) Required Actions

    (1) Within 100 hours time-in-service (TIS) and thereafter at 
intervals not to exceed 800 hours TIS, inspect each bearing for 
freedom of movement by turning and tilting the bearing as depicted 
in Figure 2 of Eurocopter Alert Service Bulletin No. EC135-67A-012, 
Revision 1, dated October 18, 2006 (ASB). During any inspection:
    (i) If there is binding or rough turning, before further flight, 
replace the bearing with an airworthy bearing.
