We will consider all the comments we receive and may conduct additional rulemaking based on those comments. PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 Discussion We issued AD 2011–27–08 (77 FR 3382, January 24, 2012) (2011–27–08), for Agusta Model A109S and AW109SP helicopters with elevator assemblies, part number (P/N) 109–0200–02–601, 109–0200–02–801, 109–0200–02–602, 109–0200–02–802, 109–0200–02–803, or 109–0200–02–804 installed. AD 2011–27–08 required repetitively inspecting the left and right elevator assemblies for a crack and replacing the elevator assembly before further flight if there is a crack. AD 2011–27–08 was prompted by AD No. 2011–0150, dated August 9, 2011 (AD 2011–0150), issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Agusta Model A109S and AW109SP helicopters. EASA advised of a fracture of the left elevator assembly along the riveting of the upper skin to the fourth rib due to fatigue. Actions Since AD 2011–27–08 Was Issued Since we issued AD 2011–27–08, EASA has issued Emergency AD No. 2017–0085–E, dated May 12, 2017 (EAD 2017–0085–E), which supersedes AD 2011–0150. EASA advises that since AD 2011–0150 was issued, another crack was found in an elevator assembly during a post-flight inspection on an A109S helicopter. EAD 2017–0085–E requires a one-time visual or dyepenetrant inspection of the elevator upper skin in the area of the fourth rib, and also requires drilling an access hole in each elevator and performing repetitive inspections of the internal areas with an endoscope. If there is a crack, EAD 2017–0085–E requires replacing the cracked elevator assembly or contacting Agusta for an approved repair. Also, the FAA is in the process of updating Agusta’s name change to Leonardo Helicopters S.p.A. on its FAA type certificate. Because this name change is not yet effective, this AD specifies Agusta. 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 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. E:\FR\FM\20DER1.SGM 20DER1 Federal Register / Vol. 82, No. 243 / Wednesday, December 20, 2017 / Rules and Regulations Related Service Information Under 1 CFR Part 51 Leonardo Helicopters has issued Emergency Alert Service Bulletin (EASB) No. 109S–076 for Model A109S helicopters, and EASB No. 109SP–113 for Model AW109SP helicopters, both Revision A and dated May 12, 2017. Each EASB specifies procedures for visually inspecting the elevator assembly skin for a crack, adding an inspection hole to the elevator assembly, and inspecting the interior of the elevator assembly with an endoscope. This service information is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section. AD Requirements This AD retains the initial visual inspection of AD 2011–27–08, but changes the compliance time to before further flight or before the elevator assembly exceeds 400 hours TIS, whichever occurs later. The AD also requires, within 10 hours TIS or before the elevator assembly exceeds 400 hours TIS, whichever occurs later, drilling an access hole on the lower face of each elevator assembly and performing a borescope inspection of the internal areas of the elevator assembly leading edge and trailing edge longerons and upper web for a crack. If there is a crack, the AD requires replacing the elevator assembly before further flight. Lastly, this AD requires repeating the borescope inspection every 25 hours TIS. Differences Between This AD and the EASA AD The EASA AD allows a dye-penetrant inspection of the elevator assembly as an option, while this AD does not. ethrower on DSK3G9T082PROD with RULES Costs of Compliance We estimate that this AD will affect 14 helicopters of U.S. Registry. At an average labor rate of $85 per hour, we estimate that operators may incur the following costs in order to comply with this AD. Inspecting the elevator assemblies with a magnifying glass will require 3 work-hours for a cost of $255 per helicopter and $3,570 for the U.S. fleet. Drilling an access hole will require 1 work-hour and required parts cost would be minimal, for a cost of $85 per helicopter and $1,190 for the U.S. fleet. Inspecting with a borescope will require 1 work-hour for a cost of $85 per helicopter and $1,190 for the U.S. fleet per inspection cycle. VerDate Sep<11>2014 16:19 Dec 19, 2017 Jkt 244001 If required, replacing a cracked elevator assembly will require 10 workhours and required parts will cost $23,905 for a cost per helicopter of $24,755. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because some of the corrective actions must be accomplished before further flight. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, we find 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); PO 00000 Frm 00019 Fmt 4700 Sfmt 4700 60299 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 issued AD 2011-27-08 (77 FR 3382, January 24, 2012) (2011-27-
08), for Agusta Model A109S and AW109SP helicopters with elevator 
assemblies, part number (P/N) 109-0200-02-601, 109-0200-02-801, 109-
0200-02-602, 109-0200-02-802, 109-0200-02-803, or 109-0200-02-804 
installed. AD 2011-27-08 required repetitively inspecting the left and 
right elevator assemblies for a crack and replacing the elevator 
assembly before further flight if there is a crack. AD 2011-27-08 was 
prompted by AD No. 2011-0150, dated August 9, 2011 (AD 2011-0150), 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union, to correct an unsafe condition for Agusta Model 
A109S and AW109SP helicopters. EASA advised of a fracture of the left 
elevator assembly along the riveting of the upper skin to the fourth 
rib due to fatigue.

Actions Since AD 2011-27-08 Was Issued

    Since we issued AD 2011-27-08, EASA has issued Emergency AD No. 
2017-0085-E, dated May 12, 2017 (EAD 2017-0085-E), which supersedes AD 
2011-0150. EASA advises that since AD 2011-0150 was issued, another 
crack was found in an elevator assembly during a post-flight inspection 
on an A109S helicopter. EAD 2017-0085-E requires a one-time visual or 
dye-penetrant inspection of the elevator upper skin in the area of the 
fourth rib, and also requires drilling an access hole in each elevator 
and performing repetitive inspections of the internal areas with an 
endoscope. If there is a crack, EAD 2017-0085-E requires replacing the 
cracked elevator assembly or contacting Agusta for an approved repair.
    Also, the FAA is in the process of updating Agusta's name change to 
Leonardo Helicopters S.p.A. on its FAA type certificate. Because this 
name change is not yet effective, this AD specifies Agusta.

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 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 Under 1 CFR Part 51

    Leonardo Helicopters has issued Emergency Alert Service Bulletin 
(EASB) No. 109S-076 for Model A109S helicopters, and EASB No. 109SP-113 
for Model AW109SP helicopters, both Revision A and dated May 12, 2017. 
Each EASB specifies procedures for visually inspecting the elevator 
assembly skin for a crack, adding an inspection hole to the elevator 
assembly, and inspecting the interior of the elevator assembly with an 
endoscope.
    This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

AD Requirements

    This AD retains the initial visual inspection of AD 2011-27-08, but 
changes the compliance time to before further flight or before the 
elevator assembly exceeds 400 hours TIS, whichever occurs later.
    The AD also requires, within 10 hours TIS or before the elevator 
assembly exceeds 400 hours TIS, whichever occurs later, drilling an 
access hole on the lower face of each elevator assembly and performing 
a borescope inspection of the internal areas of the elevator assembly 
leading edge and trailing edge longerons and upper web for a crack. If 
there is a crack, the AD requires replacing the elevator assembly 
before further flight. Lastly, this AD requires repeating the borescope 
inspection every 25 hours TIS.

Differences Between This AD and the EASA AD

    The EASA AD allows a dye-penetrant inspection of the elevator 
assembly as an option, while this AD does not.

Costs of Compliance

    We estimate that this AD will affect 14 helicopters of U.S. 
Registry.
    At an average labor rate of $85 per hour, we estimate that 
operators may incur the following costs in order to comply with this 
AD. Inspecting the elevator assemblies with a magnifying glass will 
require 3 work-hours for a cost of $255 per helicopter and $3,570 for 
the U.S. fleet.
    Drilling an access hole will require 1 work-hour and required parts 
cost would be minimal, for a cost of $85 per helicopter and $1,190 for 
the U.S. fleet.
    Inspecting with a borescope will require 1 work-hour for a cost of 
$85 per helicopter and $1,190 for the U.S. fleet per inspection cycle.
    If required, replacing a cracked elevator assembly will require 10 
work-hours and required parts will cost $23,905 for a cost per 
helicopter of $24,755.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because some of the corrective actions must be accomplished before 
further flight. Therefore, we find good cause that notice and 
opportunity for prior public comment are impracticable. In addition, 
for the reason stated above, we find 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);
    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.
