Download as PDF 38950 Federal Register / Vol. 86, No. 139 / Friday, July 23, 2021 / Proposed Rules Comments The FAA received comments from Gulfstream and an individual commenter. Requests Gulfstream requested that the FAA change the credit for previous actions. The individual commenter requested the FAA clarify the correct revision of the service information to reference. The FAA acknowledges these comments. However, because the NPRM is being withdrawn, the commenters’ requests are no longer necessary. Withdrawal of the NPRM constitutes only such action and does not preclude the FAA from further rulemaking on this issue, nor does it commit the FAA to any course of action in the future. Regulatory Findings Since this action only withdraws an NPRM, it is neither a proposed AD nor a final rule. This action, therefore, is not covered under Executive Order 12866 or the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Withdrawal Accordingly, the notice of proposed rulemaking, which published in the Federal Register on July 28, 2020 (85 FR 45345), is withdrawn. ■ Issued on July 15, 2021.

Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018–0203, dated September 12, 2018 (EASA AD 2018–0203), to correct an unsafe condition for Leonardo S.p.A., formerly Finmeccanica S.p.A. and AgustaWestland S.p.A., Model AW169 helicopters, all serial numbers equipped with pilot collective stick assemblies having part number (P/N) 6F6711A07832 or P/N 6F6711A07831. This proposed AD was prompted by reports of in-flight pilot collective stick oscillation. Based on the investigation results, it was determined that this was likely due to an incorrect adjustment on the collective stick fixed friction during helicopter assembly, or during a maintenance action. Incorrect adjustment of the collective friction of the flight control system could lead to a reduction in the safety margins of controllability of an affected helicopter. To address this issue, EASA issued AD 2017–0137, dated August 1, 2017, to require a one-time measurement of the collective stick fixed friction value. After that EASA AD was issued an additional event was reported involving a helicopter that was not affected by EASA AD 2017–0137. EASA AD 2018– 0203 supersedes EASA AD 2017–0137. The FAA is proposing this AD to address incorrect adjustment of the pilot collective stick fixed friction. The unsafe condition, if not addressed, could result in reduced controllability of the helicopter, and subsequent damage to the helicopter and injury to occupants. See EASA AD 2018–0203 for additional background information. Related Service Information Under 1 CFR Part 51 EASA AD 2018–0203 requires a onetime measurement of the friction of the pilot collective stick assembly to verify that it is within the allowable range specified in the service information (collective up and collective down directions 9.00/18.00N (Newton) or 2.02/4.05 lbf (pound force)) and, depending on the findings, accomplishment of the corrective action. The corrective action is making an adjustment to the pilot collective stick assembly to restore the acceptable level of friction. EASA AD 2018–0203 also specifies that after installation of an affected part, or following maintenance of an affected part that involves removal from the helicopter and re-installation, before the next flight after the part installation, the collective fixed friction must be measured and, depending on the findings, the corrective action must be accomplished. This material 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. FAA’s Determination and Requirements of This Proposed AD 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 proposing 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. Proposed AD Requirements in This NPRM This proposed AD would require accomplishing the actions specified in EASA AD 2018–0203, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this proposed AD. Explanation of Required Compliance Information In the FAA’s ongoing efforts to improve the efficiency of the AD process, the FAA developed a process to use certain civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has been coordinating this process with manufacturers and CAAs. As a result, EASA AD 2018–0203 will be incorporated by reference in the FAA final rule. This proposed AD would, therefore, require compliance with EASA AD 2018–0203 in its entirety, through that incorporation, except for any differences identified as exceptions in the regulatory text of this proposed AD. Using common terms that are the same as the heading of a particular section in EASA AD 2018– 0203 does not mean that operators need comply only with that section. For example, where the AD requirement refers to ‘‘all required actions and compliance times,’’ compliance with this AD requirement is not limited to the section titled ‘‘Required Action(s) and Compliance Time(s)’’ in EASA AD 2018–0203. Service information specified in EASA AD 2018–0203 that is required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–0578 after the FAA final rule is published. Costs of Compliance The FAA estimates that this AD, if adopted as proposed, would affect 6 helicopters of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: khammond on DSKJM1Z7X2PROD with PROPOSALS ESTIMATED COSTS Action Labor cost Functional check—friction measurement ........ 2 work-hours × $85 per hour = $170 .............

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 The FAA 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 above, I certify this proposed regulation: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, (2) Would not affect intrastate aviation in Alaska, and (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. khammond on DSKJM1Z7X2PROD with PROPOSALS List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2018-0203, dated September 12, 2018 
(EASA AD 2018-0203), to correct an unsafe condition for Leonardo 
S.p.A., formerly Finmeccanica S.p.A. and AgustaWestland S.p.A., Model 
AW169 helicopters, all serial numbers equipped with pilot collective 
stick assemblies having part number (P/N) 6F6711A07832 or P/N 
6F6711A07831.
    This proposed AD was prompted by reports of in-flight pilot 
collective stick oscillation. Based on the investigation results, it 
was determined that this was likely due to an incorrect adjustment on 
the collective stick fixed friction during helicopter assembly, or 
during a maintenance action. Incorrect adjustment of the collective 
friction of the flight control system could lead to a reduction in the 
safety margins of controllability of an affected helicopter. To address 
this issue, EASA issued AD 2017-0137, dated August 1, 2017, to require 
a one-time measurement of the collective stick fixed friction value. 
After that EASA AD was issued an additional event was reported 
involving a helicopter that was not affected by EASA AD 2017-0137. EASA 
AD 2018-0203 supersedes EASA AD 2017-0137. The FAA is proposing this AD 
to address incorrect adjustment of the pilot collective stick fixed 
friction. The unsafe condition, if not addressed, could result in 
reduced controllability of the helicopter, and subsequent damage to the 
helicopter and injury to occupants. See EASA AD 2018-0203 for 
additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2018-0203 requires a one-time measurement of the friction 
of the pilot collective stick assembly to verify that it is within the 
allowable range specified in the service information (collective up and 
collective down directions 9.00/18.00N (Newton) or 2.02/4.05 lbf (pound 
force)) and, depending on the findings, accomplishment of the 
corrective action. The corrective action is making an adjustment to the 
pilot collective stick assembly to restore the acceptable level of 
friction. EASA AD 2018-0203 also specifies that after installation of 
an affected part, or following maintenance of an affected part that 
involves removal from the helicopter and re-installation, before the 
next flight after the part installation, the collective fixed friction 
must be measured and, depending on the findings, the corrective action 
must be accomplished.
    This material 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.

FAA's Determination and Requirements of This Proposed AD

    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 proposing 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.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2018-0203, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD.

Explanation of Required Compliance Information

    In the FAA's ongoing efforts to improve the efficiency of the AD 
process, the FAA developed a process to use certain civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2018-0203 will be incorporated by reference in the FAA final 
rule. This proposed AD would, therefore, require compliance with EASA 
AD 2018-0203 in its entirety, through that incorporation, except for 
any differences identified as exceptions in the regulatory text of this 
proposed AD. Using common terms that are the same as the heading of a 
particular section in EASA AD 2018-0203 does not mean that operators 
need comply only with that section. For example, where the AD 
requirement refers to ``all required actions and compliance times,'' 
compliance with this AD requirement is not limited to the section 
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2018-
0203. Service information specified in EASA AD 2018-0203 that is 
required for compliance with it will be available at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0578 after the FAA final rule is published.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 6 helicopters of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

    The FAA estimates the following costs to do any necessary 
adjustment that would be required based on the results of the proposed 
inspection. The agency has no way of determining the number of 
helicopters that might need this adjustment:

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

    The FAA 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 above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13   [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive:

Leonardo S.p.a.: Docket No. FAA-2021-0578; Project Identifier 2018-
SW-084-AD.

(a) Comments Due Date

    The FAA must receive comments on this airworthiness directive 
(AD) by September 7, 2021.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Leonardo S.p.a. Model AW169 helicopters, 
certificated in any category, with an affected part as identified in 
European Aviation Safety Agency (now European Union Aviation Safety 
Agency) (EASA) AD 2018-0203, dated September 12, 2018 (EASA AD 2018-
0203) installed.

(d) Subject

    Joint Aircraft Service Component (JASC) Codes: 6700, Rotorcraft 
Flight Control; 6710, Main Rotor Control.

(e) Unsafe Condition

    This AD was prompted by reports of in-flight pilot collective 
stick oscillation. The FAA is issuing this AD address incorrect 
adjustment of the pilot collective stick fixed friction. The unsafe 
condition, if not addressed, could result in reduced controllability 
of the helicopter, and subsequent damage to the helicopter and 
injury to occupants.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Requirements

    Except as specified in paragraph (h) of this AD: Comply with all 
required actions and compliance times specified in, and in 
accordance with, EASA AD 2018-0203.

(h) Exceptions to EASA AD 2018-0203

    (1) Where EASA AD 2018-0203 refers to flight hours (FH), this AD 
requires using hours time-in-service.
    (2) Where EASA AD 2018-0203 refers to its effective date, this 
AD requires using the effective date of this AD.
    (3) The ``Remarks'' section of EASA AD 2018-0203 does not apply 
to this AD.

(i) No Reporting Requirement

    Although the service information referenced in EASA AD 2018-0203 
specifies to submit certain information to the manufacturer, this AD 
does not include that requirement.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, International Validation Branch, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information 
directly to the manager of the International Validation Branch, send 
it to the attention of the person identified in paragraph (k)(2) of 
this AD. Information may be emailed to: [email protected].
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
