Download as PDF sradovich on DSK3GMQ082PROD with RULES 55752 Federal Register / Vol. 82, No. 225 / Friday, November 24, 2017 / Rules and Regulations the denial notification letter, that the requester may incur fees as a result of processing the request. In the denial notification letter, the Council shall advise the requester that the Council will not proceed to process the request further unless the requester, in writing, directs the Council to do so and either agrees to pay any fees that may apply to processing the request or specifies an upper limit (of not less than $25) that the requester is willing to pay to process the request. If the Council does not receive this written direction and agreement/specification within thirty (30) days of the date of the denial notification letter, then the Council shall deem the FOIA request to be withdrawn. (7) Appeals of denials of requests to reduce or waive fees. If the Council denies a request to reduce or waive fees, then the requester shall have the right to submit an appeal of the denial determination in accordance with § 1301.11. The Council shall communicate this appeal right as part of its written notification to the requester denying the fee reduction or waiver request. The requester shall clearly mark its appeal request and any envelope that encloses it with the words ‘‘Appeal for Fee Reduction/Waiver.’’ (g) Notice of estimated fees; advance payments. (1) When the Council estimates the fees for processing a request will exceed the limit set by the requester, and that amount is less than $250, the Council shall notify the requester of the estimated costs, broken down by search, review and duplication fees. The requester must provide an agreement to pay the estimated costs, except that the requester may reformulate the request in an attempt to reduce the estimated fees. (2) If the requester fails to state a limit and the costs are estimated to exceed $250, the requester shall be notified of the estimated costs, broken down by search, review and duplication fees, and must pay such amount prior to the processing of the request, or provide satisfactory assurance of full payment if the requester has a history of prompt payment of FOIA fees. Alternatively, the requester may reformulate the request in such a way as to constitute a request for responsive records at a reduced fee. (3) The Council reserves the right to request advance payment after a request is processed and before records are released. (4) If a requester previously has failed to pay a fee within thirty (30) calendar days of the date of the billing, the requester shall be required to pay the full amount owed plus any applicable interest, and to make an advance VerDate Sep<11>2014 16:12 Nov 22, 2017 Jkt 244001 payment of the full amount of the estimated fee before the Council begins to process a new request or the pending request. (h) Form of payment. Payment may be made by check or money order paid to the Treasurer of the United States. (i) Charging interest. The Council may charge interest on any unpaid bill starting on the 31st day following the date of billing the requester. Interest charges will be assessed at the rate provided in 31 U.S.C. 3717 and will accrue from the date of the billing until payment is received by the Council. The Council will follow the provisions of the Debt Collection Act of 1982 (Pub. L. 97– 365, 96 Stat. 1749), as amended, and its administrative procedures, including the use of consumer reporting agencies, collection agencies, and offset. (j) Aggregating requests. If the Council reasonably determines that a requester or a group of requesters acting together is attempting to divide a request into a series of requests for the purpose of avoiding fees, the Council may aggregate those requests and charge accordingly. The Council may presume that multiple requests involving related matters submitted within a thirty (30) calendar day period have been made in order to avoid fees. The Council shall not aggregate multiple requests involving unrelated matters. Dated: November 16, 2017. Eric A. Froman, Executive Director, Financial Stability Oversight Council.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: sradovich on DSK3GMQ082PROD with RULES 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 2014–24–02, Amendment 39–18035 (79 FR 70785, November 28, 2014) (AD 2014–24–02), for Agusta S.p.A. Model AB139 and AW139 helicopters with a M/R rotating scissors part number (P/N) 3G6230A00733 with a bearing P/N 3G6230V00654 installed. AD 2014–24– 02 required repetitive inspections of the M/R rotating scissors for damage and play of the bearing and replacing the nut with a special nut, P/N 3G6230A06851, which lengthens the compliance time for repetitive inspections. AD 2014–24– 02 was prompted by AD No. 2014– 0215–E, dated September 24, 2014, issued by EASA, which is the Technical Agent for the Member States of the European Union. EASA AD No. 2014– 0215–E corrected an unsafe condition for the AgustaWestland S.p.A and AgustaWestland Philadelphia Corporation Model AB139 and AW139 VerDate Sep<11>2014 16:12 Nov 22, 2017 Jkt 244001 Actions Since AD 2014–24–02 Was Issued Since we issued AD 2014–24–02, EASA issued AD No. 2017–0028–E, dated February 15, 2017, which supersedes AD No. 2014–0215–E. EASA AD No. 2017–0028–E was prompted by a report of a dislodged bearing P/N 3G6230V00654 with special nut P/N 3G6230A06851 installed. EASA advises that all bearings P/N 3G6230V00654 could prematurely damage or wear, including those with the special nut. For these reasons, EASA AD No. 2017– 0028–E partially retains the repetitive inspections and requires replacement of the bearing with improved bearing P/N 3G6230V00655 as terminating action for the inspections. Additionally, Agusta S.p.A. has changed its name to Leonardo Helicopters. Because the FAA is in the process of updating this name change on its FAA type certificate and it is not yet effective, this AD specifies Agusta S.p.A. as the type certificate holder. 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 We reviewed Leonardo Helicopters (previously Agusta S.p.A.) Alert Bollettino Tecnico No. 139–392, Revision A, dated February 14, 2017. This service information specifies repetitively inspecting the M/R rotating scissors to monitor the bearings and replacing the bearing with a new partnumbered bearing. 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. Other Related Service Information We reviewed Leonardo Helicopters AW139 IETP Document Code AMP–39– C–62–31–00–00A–31AC–A, Rotating control installation—Fixed swashplate and rotating scissors—Detailed PO 00000 Frm 00031 Fmt 4700 Sfmt 4700 55753 inspection, Issue 29, dated July 31, 2017. This service information describes procedures for a detailed inspection of the fixed swashplate and rotating scissors. AD Requirements This new AD reduces the inspection interval for some M/R rotating scissors, clarifies the inspection for damage, adds an inspection for movement of the bearing out of its seat, and retains the inspection for play of the bearing. Depending on the outcome of these inspections, this AD requires replacing the bearing with an improved bearing, replacing the rotating scissor attachment flange with a certain part-numbered rotating scissor attachment flange, and replacing the nut with a certain partnumbered special nut. If not done as a result of the inspections, this AD also requires replacing each nut with a certain part-numbered special nut. Differences Between This AD and the EASA AD The EASA AD requires replacing each bearing P/N 3G6230V00654 with bearing P/N 3G6230V00655 within 12 months; whereas, this AD does not. We plan to publish a notice of proposed rulemaking to give the public an opportunity to comment on this longterm requirement. Costs of Compliance We estimate that this AD affects 103 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Inspecting for bearing liner wear, seat movement, and play will take about 1 work-hour for a cost of $85 per helicopter and $8,755 for the U.S. fleet per inspection cycle. Replacing a bearing will take 2 work-hours and parts will cost $892 for a cost of $1,062 per bearing. Replacing a rotating scissor attachment flange will cost $20,629 for parts and no additional labor. Installing two special nuts on a helicopter will take 1 work-hour and parts will cost $682 for a cost of $767 helicopter and $79,001 for the U.S. fleet. According to Leonardo Helicopter’s service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Leonardo Helicopter. Accordingly, we have included all costs in our cost estimate. FAA’s Justification and Determination of the Effective Date Providing an opportunity for public comments prior to adopting these AD E:\FR\FM\24NOR1.SGM 24NOR1 55754 Federal Register / Vol. 82, No. 225 / Friday, November 24, 2017 / Rules and Regulations 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 the adoption of this rule because the unsafe condition can adversely affect the controllability of the helicopter and some of the required corrective actions must be accomplished within 5 hours time-inservice and thereafter every 24 hours. Other corrective actions in this AD must be accomplished within 100 hours timein-service; however, these helicopters are generally high-usage aircraft and could reach this compliance time within a very short calendar time. 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 that good cause exists for making this amendment effective in less than 30 days. sradovich on DSK3GMQ082PROD with RULES 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); VerDate Sep<11>2014 16:12 Nov 22, 2017 Jkt 244001 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1. The authority citation for part 39 continues to read as follows: ■ Authority: 49 U.S.C. 106(g), 40113, 44701. § 39.13 [Amended] 2. The FAA amends § 39.13 by removing Airworthiness Directive (AD) 2014–24–02, Amendment 39–18035 (79 FR 70785, November 28, 2014), and adding the following new AD: ■ 2017–23–08 Agusta S.p.A.: Amendment 39– 19102; Docket No. FAA–2017–0982; Product Identifier 2017–SW–009–AD.

SUPPLEMENTARY INFORMATION: Discussion The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA Airworthiness Directive 2017–0118, dated July 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain ATR—GIE Avions ´ de Transport Regional Model ATR42– 500 airplanes and Model ATR72–212A airplanes. The MCAI states: An event was reported of several spurious alarms on a recently delivered ATR 72 aeroplane. During troubleshooting, damage was evidenced on the electrical harness bundle (Route 1M) due to chafing with a window blinding panel located on the left hand of the fuselage, zone 231. A bracket, necessary to maintain the harness bundle close to the structure of the fuselage and avoid chafing, was missing. Same bracket has also been found missing on the other side of the fuselage (symmetrical location, Right Hand side, zone 232, route 2M) with no damage on the harness bundle. A quality investigation revealed another aeroplane on the production line, where same brackets were not installed.

Airworthiness Directives; Agusta S.p.A. Helicopters

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule; request for comments.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-24-02 for 
Agusta S.p.A. (Agusta) Model AB139 and AW139 helicopters. AD 2014-24-02 
required repetitively inspecting the main rotor (M/R) rotating 
scissors, removing certain lower half scissor spherical bearings 
(bearings) from service, and installing a special nut. This new AD 
revises the inspection requirements and requires replacing the 
bearings. This AD is prompted by a new report of a dislodged bearing of 
an M/R rotating scissor. The actions of this AD are intended to correct 
an unsafe condition on these products.

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 2014-24-02, Amendment 39-18035 (79 FR 70785, November 
28, 2014) (AD 2014-24-02), for Agusta S.p.A. Model AB139 and AW139 
helicopters with a M/R rotating scissors part number (P/N) 3G6230A00733 
with a bearing P/N 3G6230V00654 installed. AD 2014-24-02 required 
repetitive inspections of the M/R rotating scissors for damage and play 
of the bearing and replacing the nut with a special nut, P/N 
3G6230A06851, which lengthens the compliance time for repetitive 
inspections. AD 2014-24-02 was prompted by AD No. 2014-0215-E, dated 
September 24, 2014, issued by EASA, which is the Technical Agent for 
the Member States of the European Union. EASA AD No. 2014-0215-E 
corrected an unsafe condition for the AgustaWestland S.p.A and 
AgustaWestland Philadelphia Corporation Model AB139 and AW139 
helicopters. EASA advised of reports of early excessive play in the 
bearings and a report of a chipped bearing liner.

Actions Since AD 2014-24-02 Was Issued

    Since we issued AD 2014-24-02, EASA issued AD No. 2017-0028-E, 
dated February 15, 2017, which supersedes AD No. 2014-0215-E. EASA AD 
No. 2017-0028-E was prompted by a report of a dislodged bearing P/N 
3G6230V00654 with special nut P/N 3G6230A06851 installed. EASA advises 
that all bearings P/N 3G6230V00654 could prematurely damage or wear, 
including those with the special nut. For these reasons, EASA AD No. 
2017-0028-E partially retains the repetitive inspections and requires 
replacement of the bearing with improved bearing P/N 3G6230V00655 as 
terminating action for the inspections.
    Additionally, Agusta S.p.A. has changed its name to Leonardo 
Helicopters. Because the FAA is in the process of updating this name 
change on its FAA type certificate and it is not yet effective, this AD 
specifies Agusta S.p.A. as the type certificate holder.

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

    We reviewed Leonardo Helicopters (previously Agusta S.p.A.) Alert 
Bollettino Tecnico No. 139-392, Revision A, dated February 14, 2017. 
This service information specifies repetitively inspecting the M/R 
rotating scissors to monitor the bearings and replacing the bearing 
with a new part-numbered bearing.
    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.

Other Related Service Information

    We reviewed Leonardo Helicopters AW139 IETP Document Code AMP-39-C-
62-31-00-00A-31AC-A, Rotating control installation--Fixed swashplate 
and rotating scissors--Detailed inspection, Issue 29, dated July 31, 
2017. This service information describes procedures for a detailed 
inspection of the fixed swashplate and rotating scissors.

AD Requirements

    This new AD reduces the inspection interval for some M/R rotating 
scissors, clarifies the inspection for damage, adds an inspection for 
movement of the bearing out of its seat, and retains the inspection for 
play of the bearing. Depending on the outcome of these inspections, 
this AD requires replacing the bearing with an improved bearing, 
replacing the rotating scissor attachment flange with a certain part-
numbered rotating scissor attachment flange, and replacing the nut with 
a certain part-numbered special nut. If not done as a result of the 
inspections, this AD also requires replacing each nut with a certain 
part-numbered special nut.

Differences Between This AD and the EASA AD

    The EASA AD requires replacing each bearing P/N 3G6230V00654 with 
bearing P/N 3G6230V00655 within 12 months; whereas, this AD does not. 
We plan to publish a notice of proposed rulemaking to give the public 
an opportunity to comment on this long-term requirement.

Costs of Compliance

    We estimate that this AD affects 103 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour. 
Inspecting for bearing liner wear, seat movement, and play will take 
about 1 work-hour for a cost of $85 per helicopter and $8,755 for the 
U.S. fleet per inspection cycle. Replacing a bearing will take 2 work-
hours and parts will cost $892 for a cost of $1,062 per bearing. 
Replacing a rotating scissor attachment flange will cost $20,629 for 
parts and no additional labor. Installing two special nuts on a 
helicopter will take 1 work-hour and parts will cost $682 for a cost of 
$767 helicopter and $79,001 for the U.S. fleet.
    According to Leonardo Helicopter's service information, some of the 
costs of this AD may be covered under warranty, thereby reducing the 
cost impact on affected individuals. We do not control warranty 
coverage by Leonardo Helicopter. Accordingly, we have included all 
costs in our cost estimate.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD

[[Page 55754]]

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 the 
adoption of this rule because the unsafe condition can adversely affect 
the controllability of the helicopter and some of the required 
corrective actions must be accomplished within 5 hours time-in-service 
and thereafter every 24 hours. Other corrective actions in this AD must 
be accomplished within 100 hours time-in-service; however, these 
helicopters are generally high-usage aircraft and could reach this 
compliance time within a very short calendar time.
    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 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.

flight, replace the bearing with bearing P/N 3G6230V00655 and 
install special nut P/N 3G6230A06851. Replacing the bearing with 
bearing P/N 3G6230V00655 constitutes terminating action for the 
remaining actions of this AD for the bearing.
    (ii) Inspect each bearing for movement. Refer to Figure 9 of BT 
139-392. If the bearing moves freely out of its seat, before further 
flight, replace the rotating scissor attachment flange with flange 
P/N 3G6220A00633, replace the bearing with bearing P/N 3G6230V00655 
and install special nut P/N 3G6230A06851. Replacing the bearing with 
bearing P/N 3G6230V00655 constitutes terminating action for the 
remaining actions of this AD for the bearing.
    (iii) Inspect the M/R rotating scissors for play and wear of 
each bearing, paying particular attention to the bearing staking 
condition, by manually moving the lower half scissor along the axis 
of the spherical bearing. Refer to Figure 1 of BT 139-392. If there 
is any play or wear beyond allowable limits, before further flight, 
replace the bearing with bearing P/N 3G6230V00655 and install 
special nut P/N 3G6230A06851. Replacing the bearing with bearing P/N 
3G6230V00655 constitutes terminating action for the remaining 
actions of this AD for the bearing.
    (2) Within 100 hours TIS, replace and torque each lower half 
scissor nut with special nut P/N 3G6230A06851 to the M/R rotating 
scissor in accordance with the Compliance Instructions, Part II, 
steps 5.1 through 5.9 of BT 139-392, except you are not required to 
discard parts.
    (3) As of the effective date of this AD, do not install any M/R 
rotating scissors with a bearing P/N 3G6230V00654 installed.
