FOR FURTHER INFORMATION CONTACT: Hal Jensen, Aerospace Engineer, Operational Safety Branch, Compliance & Airworthiness Division, FAA, 950 L’Enfant Plaza N SW, Washington, DC 20024; telephone (202) 267–9167; email hal.jensen@faa.gov. SUPPLEMENTARY INFORMATION: jbell on DSKJLSW7X2PROD with RULES Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0156, dated August 24, 2017 (EASA AD 2017– 0156), to correct an unsafe condition for Leonardo S.p.A. (formerly Finmeccanica Helicopter Division, AgustaWestland) Model AW169 helicopters, all serial numbers, except those equipped with AFCS software part number (P/N) 6F2210AS0103 or later. EASA advises of false simultaneous in-flight disengagement of AFCS channels 1 and 2 that resulted from the activation of specific AFCS modes combined with the unavailability of hybrid ground speed data at take-off. Accordingly, EASA AD 2017–0156 requires temporarily amending the Limitations Section of the RFM, informing all flight crews, and thereafter, operating the VerDate Sep<11>2014 15:42 May 17, 2021 Jkt 253001 helicopter accordingly. EASA AD 2017– 0156 also requires installing AFCS software P/N 6F2210AS0103 and removing the temporary RFM revision. This condition, if not addressed, could result in temporary loss of control of the helicopter, possibly resulting in damage to the helicopter or injury to occupants. EASA initially issued EASA AD 2017–0112 dated June 26, 2017 (EASA AD 2017–0112), to address this unsafe condition. EASA issued AD 2017–0156 to supersede EASA AD 2017–0112 to require installing the newly-developed AFCS software upgrade and removal of the temporary RFM revision. FAA’s Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of the same type design. Related Service Information Under 1 CFR Part 51 The FAA reviewed Leonardo Helicopters Alert Service Bulletin No. 169–064, dated August 9, 2017. This service information specifies procedures for installing the new release of flight control computer software P/N 6F2210AS0103. 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 requires temporarily revising the Limitations Section of the existing RFM for your helicopter to add AFCS mode limitations. This AD also requires installing an AFCS software upgrade and concurrently removing that RFM revision. Differences Between This AD and the EASA AD EASA AD 2017–0156 applies to Model AW169 helicopters, except those with AFCS software P/N 6F2210AS0103 or later installed; whereas this AD applies to Model AW169 helicopters with AFCS software P/N 6F2210AS0102 or previous versions installed instead. EASA AD 2017–0156 requires installing AFCS software P/N 6F2210AS0103 and removing the temporary RFM revision within 100 flight hours or 3 months, PO 00000 Frm 00010 Fmt 4700 Sfmt 4700 whichever occurs first after its effective date, whereas this AD requires those actions within 100 hours time-in-service after the effective date of this AD instead. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. There are currently no helicopters with this type certificate affected by this AD on the U.S. Registry. Accordingly, notice and opportunity for prior public comment are unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B). In addition, for the foregoing reason(s), the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days. Comments Invited The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2021–0344; Project Identifier MCAI–2021–00381–R’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act E:\FR\FM\18MYR1.SGM 18MYR1 Federal Register / Vol. 86, No. 94 / Tuesday, May 18, 2021 / Rules and Regulations (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Hal Jensen, Aerospace Engineer, Operational Safety Branch, Compliance & Airworthiness Division, FAA, 950 L’Enfant Plaza N SW, Washington, DC 20024; telephone (202) 267–9167; email hal.jensen@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance There are no costs of compliance with this AD because there are currently no helicopters with this type certificate affected by this AD on the U.S. Registry. jbell on DSKJLSW7X2PROD 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. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section VerDate Sep<11>2014 15:42 May 17, 2021 Jkt 253001 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 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, and (2) Will not affect intrastate aviation in Alaska. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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 adding the following new airworthiness directive: ■ PO 00000 Frm 00011 Fmt 4700 Sfmt 4700 26835 2021–10–01 Leonardo S.p.a.: Amendment 39–21534; Docket No. FAA–2021–0344; Project Identifier MCAI–2021–00381–R.

Model AW169 helicopters, certificated in any category, with automatic flight control system (AFCS) software part number (P/N) 6F2210AS0102 or previous versions installed. (d) Subject Joint Aircraft Service Component (JASC) Code: 2200, Auto Flight System. (e) Unsafe Condition This AD was prompted by false simultaneous in-flight disengagement of AFCS channels 1 and 2. The FAA is issuing this AD to address concurrent disengagement of those AFCS channels resulting from the activation of specific AFCS modes combined with the unavailability of hybrid ground speed data at take-off. The unsafe condition, if not addressed, could result in temporary loss of control of the helicopter and subsequent damage to the helicopter or injury to occupants. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions (1) Within 15 hours time-in-service (TIS) after the effective date of this AD, revise the Limitations Section of the existing Rotorcraft Flight Manual (RFM) for your helicopter by adding the information in Figure 1 to paragraph (g)(1) of this AD. Inserting a different document with information identical to the information in Figure 1 to paragraph (g)(1) of this AD is acceptable for compliance with the requirements of this paragraph. This action may be performed by the owner/operator (pilot) holding at least a private pilot certificate and must be entered into the aircraft records showing compliance with this AD in accordance with § 43.9(a)(1) through (4) and § 91.417(a)(2)(v). The record must be maintained as required by § 91.417, § 121.380, or § 135.439. E:\FR\FM\18MYR1.SGM 18MYR1 26836 Federal Register / Vol. 86, No. 94 / Tuesday, May 18, 2021 / Rules and Regulations AFCS MODE LIMITATIONS If "F" symbol is displayed next to groundspeed readout (GS) at the bottom of the IAS tape on PFD, APP/NAV AFCS modes must not be used when the navigation source is VOR/ILS/LOC. Therefore VOR navigation and VOR/ILS/LOC approaches must not be coupled to AFCS but are allowed if manually flown by the pilot. NOTE The "F" symbol displayed next to groundspeed readout (GS) is due to: - ADAHRS/GPS degradation or - "DG" mode selection In both cases the groundspeed (GS) data source is FMS instead of GPS. Figure 1 to Paragraph (g)(l) jbell on DSKJLSW7X2PROD with RULES (h) Special Flight Permits If AFCS software P/N 6F2210AS0102 or a previous version is installed, VOR navigation and VOR/ILS/LOC approaches coupled to AFCS are prohibited; VOR navigation and VOR/ILS/LOC approaches are allowed if manually flown by the pilot.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2017-0156, dated August 24, 2017 
(EASA AD 2017-0156), to correct an unsafe condition for Leonardo S.p.A. 
(formerly Finmeccanica Helicopter Division, AgustaWestland) Model AW169 
helicopters, all serial numbers, except those equipped with AFCS 
software part number (P/N) 6F2210AS0103 or later. EASA advises of false 
simultaneous in-flight disengagement of AFCS channels 1 and 2 that 
resulted from the activation of specific AFCS modes combined with the 
unavailability of hybrid ground speed data at take-off. Accordingly, 
EASA AD 2017-0156 requires temporarily amending the Limitations Section 
of the RFM, informing all flight crews, and thereafter, operating the 
helicopter accordingly. EASA AD 2017-0156 also requires installing AFCS 
software P/N 6F2210AS0103 and removing the temporary RFM revision. This 
condition, if not addressed, could result in temporary loss of control 
of the helicopter, possibly resulting in damage to the helicopter or 
injury to occupants.
    EASA initially issued EASA AD 2017-0112 dated June 26, 2017 (EASA 
AD 2017-0112), to address this unsafe condition. EASA issued AD 2017-
0156 to supersede EASA AD 2017-0112 to require installing the newly-
developed AFCS software upgrade and removal of the temporary RFM 
revision.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA about the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all known relevant information and determining that the 
unsafe condition described previously is likely to exist or develop on 
other helicopters of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Leonardo Helicopters Alert Service Bulletin No. 
169-064, dated August 9, 2017. This service information specifies 
procedures for installing the new release of flight control computer 
software P/N 6F2210AS0103.
    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 requires temporarily revising the Limitations Section of 
the existing RFM for your helicopter to add AFCS mode limitations. This 
AD also requires installing an AFCS software upgrade and concurrently 
removing that RFM revision.

Differences Between This AD and the EASA AD

    EASA AD 2017-0156 applies to Model AW169 helicopters, except those 
with AFCS software P/N 6F2210AS0103 or later installed; whereas this AD 
applies to Model AW169 helicopters with AFCS software P/N 6F2210AS0102 
or previous versions installed instead. EASA AD 2017-0156 requires 
installing AFCS software P/N 6F2210AS0103 and removing the temporary 
RFM revision within 100 flight hours or 3 months, whichever occurs 
first after its effective date, whereas this AD requires those actions 
within 100 hours time-in-service after the effective date of this AD 
instead.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause. There are currently no helicopters with 
this type certificate affected by this AD on the U.S. Registry. 
Accordingly, notice and opportunity for prior public comment are 
unnecessary, pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, for the foregoing reason(s), the FAA finds that good 
cause exists pursuant to 5 U.S.C. 553(d) for making this amendment 
effective in less than 30 days.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0344; Project Identifier MCAI-
2021-00381-R'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act

[[Page 26835]]

(FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your 
comments responsive to this AD contain commercial or financial 
information that is customarily treated as private, that you actually 
treat as private, and that is relevant or responsive to this AD, it is 
important that you clearly designate the submitted comments as CBI. 
Please mark each page of your submission containing CBI as ``PROPIN.'' 
The FAA will treat such marked submissions as confidential under the 
FOIA, and they will not be placed in the public docket of this AD. 
Submissions containing CBI should be sent to Hal Jensen, Aerospace 
Engineer, Operational Safety Branch, Compliance & Airworthiness 
Division, FAA, 950 L'Enfant Plaza N SW, Washington, DC 20024; telephone 
(202) 267-9167; email [email protected]. Any commentary that the FAA 
receives which is not specifically designated as CBI will be placed in 
the public docket for this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    There are no costs of compliance with this AD because there are 
currently no helicopters with this type certificate affected by this AD 
on the U.S. Registry.

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.
    The FAA is 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

    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, and
    (2) Will not affect intrastate aviation in Alaska.
