This AD requires visually inspecting each DATES: PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 E:\FR\FM\25OCR1.SGM 25OCR1 63854 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations pitch horn for a crack. This AD also requires, if there is a crack, before further flight, replacing the pitch horn with an airworthy pitch horn. This AD is prompted by a report of a crack in the yoke of a pitch horn. These actions are intended to detect a crack in the pitch horn to prevent failure of the pitch horn, loss of the anti-torque function, and subsequent loss of control of the helicopter. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2013– 0133, dated June 28, 2013, to correct an unsafe condition for the Model AS350B, AS350BA, AS350BB, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. EASA advises of an ongoing investigation of a crack in the yoke of a pitch horn for which a cause has not been determined. The EASA AD requires repetitive visual inspections of each pitch horn for a crack and replacing the pitch horn with a serviceable assembly if a crack is found. EASA states that its AD is an interim action and further action may follow. emcdonald on DSK67QTVN1PROD 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. Related Service Information Eurocopter has issued one Emergency Alert Service Bulletin, Revision 1, dated June 25, 2013 (EASB), with four different numbers. EASB No.05.00.74 is for Models AS350B, B1, B2, B3, BA, and D; the non-FAA type certificated Model AS350BB; and the non-FAA type certificated military Model AS350L1 helicopters. EASB No. 05.00.49 is for non-FAA type certificated military Models AS550A2, C2, C3, and U2 helicopters. EASB No. 05.00.65 is for Models AS355E, F, F1, F2, N, and NP helicopters. EASB No. 05.00.44 is for non-FAA type certificated military Model AS555AF, AN, SN, UF, and UN helicopters. Eurocopter has been informed of a case of a crack on the yoke of a pitch horn, which may lead to failure of the pitch horn, resulting in loss of the anti-torque function. The VerDate Mar<15>2010 15:42 Oct 24, 2013 Jkt 232001 EASB specifies a check for cracks on the yokes of the two pitch horns and specifies replacing any cracked pitch horn. The EASB states that it may be necessary to modify the log card of the tail rotor blade assembly due to some of the pitch horn part numbers being recorded incorrectly. AD Requirements This AD requires: • Based on the hours time-in-service, within a specified time, visually inspecting each pitch horn for a crack in the areas shown in Figure 1 of the EASB. • If there is a crack, before further flight, replacing the pitch horn with an airworthy pitch horn. • Before installing any pitch horn, P/ N 350A121368, dye penetrant inspecting it for a crack. Differences Between This AD and the EASA AD The EASA AD applies to Eurocopter Model AS350BB that does not have an FAA type certificate and therefore is not a part of this AD. The EASA AD does not apply to Eurocopter Model AS350C or the AS350D1, but this AD does because those models have an FAA type certificate and may have the applicable pitch horn installed. This AD requires a dye-penetrant inspection before installing a pitch horn; the EASA AD does not. The EASA AD applies to parts with less than 135 hours TIS, while this AD does not. The EASA AD requires the pitch horn inspection to be repeated every 165 flight hours, and this AD does not. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments before adopting these AD requirements would delay implementing the safety actions needed to correct this known unsafe condition. Therefore we find that the risk to the flying public justifies waiving notice and comment prior to adopting this rule because the corrective actions must be accomplished, for helicopters flying with parts with more than 155 hours TIS, within 10 hours TIS, a short time period based on the average flight-hour utilization rate of these helicopters. Since an unsafe condition exists that requires the immediate adoption of this AD, we determined that notice and opportunity for public comment before issuing this AD are impracticable and contrary to the public interest and that good cause exists for making this amendment effective in less than 30 days. Authority for This Rulemaking We consider this AD to be an interim action. If final action is later identified, we might consider further rulemaking then. 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. Costs of Compliance Regulatory Findings We estimate that this AD will affect 938 helicopters of U.S. Registry. We estimate that operators may incur the following costs to comply with this AD. Labor costs are estimated at $85 per work hour. We estimate .1 work hour to visually inspect a pitch horn for a total of $8.50 per helicopter and $7,973 for the fleet. We estimate 1 work hour to do a dye-penetrant inspection, for a total cost of $85 per helicopter. We estimate 1 work hour to replace a part if necessary, and a cost for required parts of $1,946, for a total cost of $2,031 per helicopter. We determined that 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, 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); Interim Action PO 00000 Frm 00032 Fmt 4700 Sfmt 4700 E:\FR\FM\25OCR1.SGM 25OCR1 Federal Register / Vol. 78, No. 207 / Friday, October 25, 2013 / Rules and Regulations 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:

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not provide you with notice and an opportunity to 
provide your comments prior to it becoming effective. However, we 
invite you to participate in this rulemaking by submitting written 
comments, data, or views. We also invite comments relating to the 
economic, environmental, energy, or federalism impacts that resulted 
from adopting this AD. The most helpful comments reference a specific 
portion of the AD, explain the reason for any recommended change, and 
include supporting data. To ensure the docket does not contain 
duplicate comments, commenters should send only one copy of written 
comments, or if comments are filed electronically, commenters should 
submit them only one time. We will file in the docket all comments that 
we receive, as well as a report summarizing each substantive public 
contact with FAA personnel concerning this rulemaking during the 
comment period. We will consider all the comments we receive and may 
conduct additional rulemaking based on those comments.

Discussion

    We are adopting a new AD for the specified Eurocopter helicopters. 
This AD requires visually inspecting each

[[Page 63854]]

pitch horn for a crack. This AD also requires, if there is a crack, 
before further flight, replacing the pitch horn with an airworthy pitch 
horn. This AD is prompted by a report of a crack in the yoke of a pitch 
horn. These actions are intended to detect a crack in the pitch horn to 
prevent failure of the pitch horn, loss of the anti-torque function, 
and subsequent loss of control of the helicopter.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
No. 2013-0133, dated June 28, 2013, to correct an unsafe condition for 
the Model AS350B, AS350BA, AS350BB, AS350B1, AS350B2, AS350B3, AS350D, 
AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. EASA 
advises of an ongoing investigation of a crack in the yoke of a pitch 
horn for which a cause has not been determined. The EASA AD requires 
repetitive visual inspections of each pitch horn for a crack and 
replacing the pitch horn with a serviceable assembly if a crack is 
found. EASA states that its AD is an interim action and further action 
may follow.

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.

Related Service Information

    Eurocopter has issued one Emergency Alert Service Bulletin, 
Revision 1, dated June 25, 2013 (EASB), with four different numbers. 
EASB No.05.00.74 is for Models AS350B, B1, B2, B3, BA, and D; the non-
FAA type certificated Model AS350BB; and the non-FAA type certificated 
military Model AS350L1 helicopters. EASB No. 05.00.49 is for non-FAA 
type certificated military Models AS550A2, C2, C3, and U2 helicopters. 
EASB No. 05.00.65 is for Models AS355E, F, F1, F2, N, and NP 
helicopters. EASB No. 05.00.44 is for non-FAA type certificated 
military Model AS555AF, AN, SN, UF, and UN helicopters. Eurocopter has 
been informed of a case of a crack on the yoke of a pitch horn, which 
may lead to failure of the pitch horn, resulting in loss of the anti-
torque function. The EASB specifies a check for cracks on the yokes of 
the two pitch horns and specifies replacing any cracked pitch horn. The 
EASB states that it may be necessary to modify the log card of the tail 
rotor blade assembly due to some of the pitch horn part numbers being 
recorded incorrectly.

AD Requirements

    This AD requires:
     Based on the hours time-in-service, within a specified 
time, visually inspecting each pitch horn for a crack in the areas 
shown in Figure 1 of the EASB.
     If there is a crack, before further flight, replacing the 
pitch horn with an airworthy pitch horn.
     Before installing any pitch horn, P/N 350A121368, dye 
penetrant inspecting it for a crack.

Differences Between This AD and the EASA AD

    The EASA AD applies to Eurocopter Model AS350BB that does not have 
an FAA type certificate and therefore is not a part of this AD. The 
EASA AD does not apply to Eurocopter Model AS350C or the AS350D1, but 
this AD does because those models have an FAA type certificate and may 
have the applicable pitch horn installed. This AD requires a dye-
penetrant inspection before installing a pitch horn; the EASA AD does 
not. The EASA AD applies to parts with less than 135 hours TIS, while 
this AD does not. The EASA AD requires the pitch horn inspection to be 
repeated every 165 flight hours, and this AD does not.

Interim Action

    We consider this AD to be an interim action. If final action is 
later identified, we might consider further rulemaking then.

Costs of Compliance

    We estimate that this AD will affect 938 helicopters of U.S. 
Registry. We estimate that operators may incur the following costs to 
comply with this AD. Labor costs are estimated at $85 per work hour. We 
estimate .1 work hour to visually inspect a pitch horn for a total of 
$8.50 per helicopter and $7,973 for the fleet. We estimate 1 work hour 
to do a dye-penetrant inspection, for a total cost of $85 per 
helicopter. We estimate 1 work hour to replace a part if necessary, and 
a cost for required parts of $1,946, for a total cost of $2,031 per 
helicopter.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments before adopting these 
AD requirements would delay implementing the safety actions needed to 
correct this known unsafe condition. Therefore we find that the risk to 
the flying public justifies waiving notice and comment prior to 
adopting this rule because the corrective actions must be accomplished, 
for helicopters flying with parts with more than 155 hours TIS, within 
10 hours TIS, a short time period based on the average flight-hour 
utilization rate of these helicopters.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and contrary to 
the public interest and that good cause exists for making this 
amendment effective in less than 30 days.

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 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, 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);

[[Page 63855]]

    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.
