AD 2014–04–14 requires removing the applicable rod end assemblies from service. AD 2014– 04–14 was prompted by AD No. 2012– 0208, dated October 5, 2012, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for AgustaWestland Model A109LUH, A109S, AW109SP, A119, and AW119 MKII helicopters. EASA advises that cases of in-flight fractures of rod end assembly, P/N M004–01H007–045, installed on main rotor lag dampers have been reported on Model A109LUH and AW109SP helicopters. An investigation revealed that two batches of rod end assemblies, P/N M004– 01H007–041 and M004–01H007–045, could have cracks, according to EASA. EASA states that this condition, if not corrected, could lead to main rotor damage, possibly resulting in loss of control of the helicopter. The actions of AD 2014–04–14 were intended to prevent such damage and loss of control of the helicopter. Actions Since AD 2014–04–14 Was Issued Between the time we published the NPRM for AD 2014–04–14 (78 FR 44042, July 23, 2013) and the Final Rule for AD 2014–04–14 (79 FR 11699, March 3, 2014), EASA issued AD No. 2013–0290, dated December 9, 2013. EASA advises in AD No. 2013–0290 that a new case of a fractured rod end assembly has been reported. According to EASA, an investigation concluded that additional batches of rod end assembly P/N M004–01H007–041 and P/N M004–01H007–045, as well as batches of P/N 109–0112–11–101 and P/ N 109–0112–22–105, could be affected by cracks. EASA consequently expanded the applicability of its AD to include the additional rod end assemblies. This proposed AD would retain the requirements of AD 2014–04–14 but expand the scope of applicable rod end assemblies. We also propose to add a provision in the Required Actions section to clarify that the AD must be complied with if the rod end assembly is removed during maintenance before 25 hours time-in-service (TIS). FAA’s Determination These helicopters have been approved by the aviation authority of Italy and are approved for operation in the United States. Pursuant to our bilateral agreement with Italy, EASA, its PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 48699 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 is likely to exist or develop on other products of the same type design. Related Service Information We reviewed AgustaWestland’s Bollettino Tecnico (BT) No. 109S–49 for Model A109S helicopters, BT No. 109SP–052 for Model AW109SP helicopters, and BT No. 119–50 for Model A119 and AW119 MKII helicopters. All of the BTs are revision A, and dated December 3, 2013. The BTs specify a one-time inspection of each rod end assembly to determine its serial number. The BTs then require removal from service of certain serialnumbered rod end assemblies because fractures had been reported on rod ends in these batches. According to the BTs, no one was injured in the helicopters, and no helicopters were damaged because of these fractures. Proposed AD Requirements This proposed AD would require removing the applicable rod end assemblies from service within 25 hours TIS or the next time maintenance of the helicopter involves removing the rod end assembly, whichever occurs first. The proposed AD would also prohibit installing the applicable rod end assemblies on any helicopter. Differences Between This Proposed AD and the EASA AD The EASA AD calls for replacing certain rod end assemblies with airworthy rod end assemblies within 25 hours TIS, 2 months, or the next time maintenance of the applicable helicopters involves removing the rod end assembly. This proposed AD would not have a calendar time requirement. The EASA AD applies to AgustaWestland Model A109LUH helicopters. This proposed AD would not apply to Model A109LUH helicopters because that model does not have a U.S. type certificate. Costs of Compliance We estimate that this proposed AD would affect 91 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: • Replacing a rod end assembly would require 1.5 work-hours for a labor cost of $128. Parts cost $3,918 for a total cost of $4,046 per helicopter, $368,186 for the U.S. fleet. E:\FR\FM\18AUP1.SGM 18AUP1 48700 Federal Register / Vol. 79, No. 159 / Monday, August 18, 2014 / Proposed Rules According to the manufacturer’s service information, costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by manufacturers. Accordingly, we have included all costs in our cost estimate. tkelley on DSK3SPTVN1PROD with PROPOSALS 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 proposed 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 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.

Certificate Currently Held By AgustaWestland S.P.A) (AgustaWestland)

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2014-04-
14 for AgustaWestland Model A109S, AW109SP, A119, and AW119 MKII 
helicopters. AD 2014-04-14 currently requires removing certain rod end 
assemblies from service because of reports of fractures. Since we 
issued AD 2014-04-14, additional fractured rod end assemblies have been 
reported. This proposed AD would retain the requirements of AD 2014-04-
14 but expand the scope of applicable rod end assemblies. These 
proposed actions are intended to prevent failure of a rod end assembly, 
which could result in damage to the main rotor assembly and loss of 
control of the helicopter.

Discussion

    On March 3, 2014, we published AD 2014-04-14, Amendment 39-17773 
(79 FR 11699) for AgustaWestland Model A109S, AW109SP, A119, and AW119 
MKII helicopters with a main rotor lag damper assembly (lag damper), 
part number (P/N) 109-0112-39-103, 109-0112-39-105, 109-0112-05-105, or 
109-0112-05-107, installed with a rod end assembly, P/N M004-01H007-041 
or P/N M004-01H007-045, with a serial number from 84 through 132 or 
from 4964 through 5011. AD 2014-04-14 requires removing the applicable 
rod end assemblies from service. AD 2014-04-14 was prompted by AD No. 
2012-0208, dated October 5, 2012, issued by EASA, which is the 
Technical Agent for the Member States of the European Union, to correct 
an unsafe condition for AgustaWestland Model A109LUH, A109S, AW109SP, 
A119, and AW119 MKII helicopters. EASA advises that cases of in-flight 
fractures of rod end assembly, P/N M004-01H007-045, installed on main 
rotor lag dampers have been reported on Model A109LUH and AW109SP 
helicopters. An investigation revealed that two batches of rod end 
assemblies, P/N M004-01H007-041 and M004-01H007-045, could have cracks, 
according to EASA. EASA states that this condition, if not corrected, 
could lead to main rotor damage, possibly resulting in loss of control 
of the helicopter. The actions of AD 2014-04-14 were intended to 
prevent such damage and loss of control of the helicopter.

Actions Since AD 2014-04-14 Was Issued

    Between the time we published the NPRM for AD 2014-04-14 (78 FR 
44042, July 23, 2013) and the Final Rule for AD 2014-04-14 (79 FR 
11699, March 3, 2014), EASA issued AD No. 2013-0290, dated December 9, 
2013. EASA advises in AD No. 2013-0290 that a new case of a fractured 
rod end assembly has been reported. According to EASA, an investigation 
concluded that additional batches of rod end assembly P/N M004-01H007-
041 and P/N M004-01H007-045, as well as batches of P/N 109-0112-11-101 
and P/N 109-0112-22-105, could be affected by cracks. EASA consequently 
expanded the applicability of its AD to include the additional rod end 
assemblies.
    This proposed AD would retain the requirements of AD 2014-04-14 but 
expand the scope of applicable rod end assemblies. We also propose to 
add a provision in the Required Actions section to clarify that the AD 
must be complied with if the rod end assembly is removed during 
maintenance before 25 hours time-in-service (TIS).

FAA's Determination

    These helicopters have been approved by the aviation authority of 
Italy and are approved for operation in the United States. Pursuant to 
our bilateral agreement with Italy, 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 is likely to exist or develop 
on other products of the same type design.

Related Service Information

    We reviewed AgustaWestland's Bollettino Tecnico (BT) No. 109S-49 
for Model A109S helicopters, BT No. 109SP-052 for Model AW109SP 
helicopters, and BT No. 119-50 for Model A119 and AW119 MKII 
helicopters. All of the BTs are revision A, and dated December 3, 2013. 
The BTs specify a one-time inspection of each rod end assembly to 
determine its serial number. The BTs then require removal from service 
of certain serial-numbered rod end assemblies because fractures had 
been reported on rod ends in these batches. According to the BTs, no 
one was injured in the helicopters, and no helicopters were damaged 
because of these fractures.

Proposed AD Requirements

    This proposed AD would require removing the applicable rod end 
assemblies from service within 25 hours TIS or the next time 
maintenance of the helicopter involves removing the rod end assembly, 
whichever occurs first. The proposed AD would also prohibit installing 
the applicable rod end assemblies on any helicopter.

Differences Between This Proposed AD and the EASA AD

    The EASA AD calls for replacing certain rod end assemblies with 
airworthy rod end assemblies within 25 hours TIS, 2 months, or the next 
time maintenance of the applicable helicopters involves removing the 
rod end assembly. This proposed AD would not have a calendar time 
requirement. The EASA AD applies to AgustaWestland Model A109LUH 
helicopters. This proposed AD would not apply to Model A109LUH 
helicopters because that model does not have a U.S. type certificate.

Costs of Compliance

    We estimate that this proposed AD would affect 91 helicopters of 
U.S. Registry and that labor costs average $85 a work-hour. Based on 
these estimates, we expect the following costs:
     Replacing a rod end assembly would require 1.5 work-hours 
for a labor cost of $128. Parts cost $3,918 for a total cost of $4,046 
per helicopter, $368,186 for the U.S. fleet.

[[Page 48700]]

    According to the manufacturer's service information, costs of this 
proposed AD may be covered under warranty, thereby reducing the cost 
impact on affected individuals. We do not control warranty coverage by 
manufacturers. Accordingly, we have included all costs in our cost 
estimate.

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 proposed 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
    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.
