Download as PDF Federal Register / Vol. 80, No. 236 / Wednesday, December 9, 2015 / Rules and Regulations margins, an increase in flight crew workload, discomfort to the flight crew, or physical distress to the passengers or cabin crew, possibly including non-fatal injuries. Significant transients do not require, in order to remain within or recover to the normal flight envelope, any of the following: i. Exceptional piloting skill, alertness, or strength. ii. Forces applied by the pilot which are greater than those specified in § 23.143(c). iii. Accelerations or attitudes in the airplane that might result in further hazard to secured or non-secured occupants. It must also be demonstrated, through tests and analysis, that no single failure or malfunction or probable combinations of failures of the auto thrust system components results in the probability for LOTC, or un-commanded thrust changes and transients that result in an LOTC event, to exceed the following: (1) Average Events per Million Hours: 10 (1×10¥05 per hour) (2) Maximum Events per Million Hours: 100 (1×10¥04 per hour) Note: The term ‘‘probable’’ in the context of ‘‘probable combination of failures’’ does not have the same meaning as used for a safety assessment process. The term ‘‘probable’’ in ‘‘probable combination of failures’’ means ‘‘foreseeable,’’ or those failure conditions anticipated to occur one or more times during the operational life of each airplane.

Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2015– 0097, dated June 1, 2015, to correct an unsafe condition for Agusta Model A109A and A109A II helicopters. EASA advises that during a scheduled 100flight-hour inspection on a Model A109A II helicopter, unusual play was detected on a part number (P/N) 109– 0130–11–7 slider. Further investigation revealed excessive wear of the slider broaching at the point of contact with the tail rotor shaft. However, the cause of the excessive play and wear has not been determined. This condition, if not detected and corrected, could lead to reduced control of the helicopter, EASA advises. EASA consequently requires repetitive inspections of slider P/N 109–0130–11– 7 more frequently than those performed at the 100-flight-hour inspection and corrective actions depending on the findings. EASA advises that its AD is an interim measure and further AD action may follow. E:\FR\FM\09DER1.SGM 09DER1 76382 Federal Register / Vol. 80, No. 236 / Wednesday, December 9, 2015 / Rules and Regulations 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 We reviewed AgustaWestland Bollettino Tecnico No. 109–149, dated May 29, 2015, for Model A109A and A109A II helicopters. The bulletin states that during a 100-flight-hour inspection of a Model A109A II helicopter, ‘‘anomalous’’ play was found on a P/N 109–0130–11–7 slider. After the slider was removed and inspected, extended, unusual wear of the broaching in the point of contact with the tail rotor shaft was found. Agusta states that the investigation is ongoing, but as a precautionary measure it is reducing the slider inspection intervals from 100 flight hours to 25 flight hours. AD Requirements This AD requires, within 25 hours time-in-service (TIS) and thereafter at intervals not to exceed 25 hours TIS, inspecting the slider for play. If there is any play that exceeds 2.3 millimeters (0.09 inch), this AD requires replacing the slider with an airworthy slider before further flight. wgreen on DSK2VPTVN1PROD with RULES Interim Action We consider this AD to be an interim action. The design approval holder has not determined the cause of the unsafe condition identified in this AD. If a cause is determined and actions developed to address the cause, we might consider additional rulemaking. Costs of Compliance We estimate that this AD will affect 36 helicopters of U.S. Registry and that labor costs average $85 a work-hour. Based on these estimates, we expect the following costs: • Inspecting the slider for play requires 1 work-hour for a labor cost of $85 per helicopter and $3060 for the U.S. fleet. • Replacing the slider requires 10 work-hours and $4068 in parts for a total cost of $4918 per helicopter. According to Agusta’s service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on VerDate Sep<11>2014 15:17 Dec 08, 2015 Jkt 238001 affected individuals. We do not control warranty coverage by Agusta. 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 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 control of the helicopter and the required corrective actions must be accomplished within 25 hours TIS. These helicopters have a variety of uses, including search-andrescue and medical flights, and are expected to accumulate 25 hours TIS within a few weeks. 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. PO 00000 Frm 00028 Fmt 4700 Sfmt 4700 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.

SUPPLEMENTARY INFORMATION: SUMMARY: Background The authority for parts 730, 734, 736, 742, 744, and 745 of the EAR rests, in part, on Executive Order 12938 of November 14, 1994—Proliferation of Weapons of Mass Destruction, 59 FR 59099, 3 CFR, 1994 Comp., p. 950 and on annual notices continuing the emergency declared in that executive order. This rule revises the authority citations for the affected parts to cite the most recent such notice, which the President signed on November 12, 2015. This rule is purely non-substantive, and makes no changes other than to revise CFR authority citations for the purpose of making the authority citations current. It does not change the text of any section of the EAR, nor does it alter any right, obligation or prohibition that applies to any person under the EAR. Rulemaking Requirements 1. Executive Orders 13563 and 12866 direct agencies to assess all costs and benefits of available regulatory alternatives and, if regulation is VerDate Sep<11>2014 15:17 Dec 08, 2015 Jkt 238001 PO 00000 Frm 00029 Fmt 4700 Sfmt 4700 76383 necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). This rule does not impose any regulatory burden on the public and is consistent with the goals of Executive Order 13563. This rule has been determined to be not significant for purposes of Executive Order 12866. 2. Notwithstanding any other provision of law, no person is required to respond to, nor shall any person be subject to a penalty for failure to comply with, a collection of information subject to the requirements of the Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.) (PRA), unless that collection of information displays a currently valid Office of Management and Budget (OMB) Control Number. This rule does not involve any collection of information. 3. This rule does not contain policies with Federalism implications as that term is defined under Executive Order 13132. 4. The Department finds that there is good cause under 5 U.S.C. 553(b)(B) to waive the provisions of the Administrative Procedure Act requiring prior notice and the opportunity for public comment because they are unnecessary. This rule only updates legal authority citations. It clarifies information and is non-discretionary. This rule does not alter any right, obligation or prohibition that applies to any person under the EAR. Because these revisions are not substantive changes, it is unnecessary to provide notice and opportunity for public comment. In addition, the 30-day delay in effectiveness otherwise required by 5 U.S.C. 553(d) is not applicable because this rule is not a substantive rule. Because neither the Administrative Procedure Act nor any other law requires that notice of proposed rulemaking and an opportunity for public comment be given for this rule, the analytical requirements of the Regulatory Flexibility Act (5 U.S.C. 601 et seq.) are not applicable. Accordingly, no Regulatory Flexibility Analysis is required and none has been prepared.

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 adopting a new airworthiness directive (AD) for Agusta 
S.p.A. (Agusta) Model A109A and A109A II helicopters. This AD requires 
inspecting the slider assembly pitch control (slider) for play and 
replacing the slider if the play exceeds certain limits. This AD is 
prompted by a report of excessive slider play and wear that was 
detected during a scheduled inspection of a Model A109A II helicopter. 
These actions are intended to detect and prevent excessive wear and 
play on a slider, which could lead to loss of tail rotor pitch control 
and consequently loss of helicopter control.

DATES: This AD becomes effective December 24, 2015.
    We must receive comments on this AD by February 8, 2016.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2015-0097, dated June 1, 2015, 
to correct an unsafe condition for Agusta Model A109A and A109A II 
helicopters. EASA advises that during a scheduled 100-flight-hour 
inspection on a Model A109A II helicopter, unusual play was detected on 
a part number (P/N) 109-0130-11-7 slider. Further investigation 
revealed excessive wear of the slider broaching at the point of contact 
with the tail rotor shaft. However, the cause of the excessive play and 
wear has not been determined.
    This condition, if not detected and corrected, could lead to 
reduced control of the helicopter, EASA advises. EASA consequently 
requires repetitive inspections of slider P/N 109-0130-11-7 more 
frequently than those performed at the 100-flight-hour inspection and 
corrective actions depending on the findings. EASA advises that its AD 
is an interim measure and further AD action may follow.

[[Page 76382]]

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

    We reviewed AgustaWestland Bollettino Tecnico No. 109-149, dated 
May 29, 2015, for Model A109A and A109A II helicopters. The bulletin 
states that during a 100-flight-hour inspection of a Model A109A II 
helicopter, ``anomalous'' play was found on a P/N 109-0130-11-7 slider. 
After the slider was removed and inspected, extended, unusual wear of 
the broaching in the point of contact with the tail rotor shaft was 
found. Agusta states that the investigation is ongoing, but as a 
precautionary measure it is reducing the slider inspection intervals 
from 100 flight hours to 25 flight hours.

AD Requirements

    This AD requires, within 25 hours time-in-service (TIS) and 
thereafter at intervals not to exceed 25 hours TIS, inspecting the 
slider for play. If there is any play that exceeds 2.3 millimeters 
(0.09 inch), this AD requires replacing the slider with an airworthy 
slider before further flight.

Interim Action

    We consider this AD to be an interim action. The design approval 
holder has not determined the cause of the unsafe condition identified 
in this AD. If a cause is determined and actions developed to address 
the cause, we might consider additional rulemaking.

Costs of Compliance

    We estimate that this AD will affect 36 helicopters of U.S. 
Registry and that labor costs average $85 a work-hour. Based on these 
estimates, we expect the following costs:
     Inspecting the slider for play requires 1 work-hour for a 
labor cost of $85 per helicopter and $3060 for the U.S. fleet.
     Replacing the slider requires 10 work-hours and $4068 in 
parts for a total cost of $4918 per helicopter.
    According to Agusta'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 Agusta. 
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 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 control of the helicopter and the required corrective 
actions must be accomplished within 25 hours TIS. These helicopters 
have a variety of uses, including search-and-rescue and medical 
flights, and are expected to accumulate 25 hours TIS within a few 
weeks.
    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);
    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.
