SUPPLEMENTARY INFORMATION: Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0245, dated November 10, 2021 (EASA AD PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 2021–0245) (also referred to as the Mandatory Continuing Airworthiness Information, or the MCAI), to correct an unsafe condition on RRD RB211 Trent 875–17, 877–17, 884–17, 884B–17, 892– 17, 892B–17, and 895–17 model turbofan engines. This AD was prompted by a report of single engine events that resulted in loss of engine thrust. An investigation by the manufacturer determined that certain engines were exposed to unacceptable levels of water contamination, which caused corrosion on the fuel pump internal components. This corrosion led to debris release and filter blockages in variable stator vane actuator control units, which resulted in the variable stator vane system failing in the closed position. This condition, if not addressed, could result in loss of engine thrust control, in-flight engine shutdown, and reduced control of the airplane. The FAA is issuing this AD to address the unsafe condition on these products. FAA’s Determination This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Community, the FAA has been notified of the unsafe condition described in the MCAI. The FAA is issuing this AD because the agency evaluated all the relevant information provided by EASA and determined the safe condition described previously is likely to exist or develop in other products of the same type design. Related Service Information Under 1 CFR Part 51 The FAA reviewed EASA AD 2021– 0245. EASA AD 2021–0245 specifies instructions for replacing certain fuel pumps and identifies certain fuel pumps that are not to be installed on an affected engine. 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 ADDRESSES. Other Related Service Information The FAA reviewed Rolls-Royce Alert Non-Modification Service Bulletin (NMSB) RB.211–73–AK788, dated November 9, 2021. The NMSB describes procedures for removing and replacing E:\FR\FM\16DER1.SGM 16DER1 71368 Federal Register / Vol. 86, No. 239 / Thursday, December 16, 2021 / Rules and Regulations Where EASA AD 2021–0245 requires compliance from its effective date, this AD requires using the effective date of this AD. This AD does not mandate compliance with the ‘‘Remarks’’ section of EASA AD 2021–0245. 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 seeking comment prior to the 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. 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. Following occurrences of single engine loss of engine thrust, the manufacturer determined that a subset of RRD RB211 Trent model turbofan engines have been exposed to unacceptable levels of water contamination. This water contamination may cause corrosion on the fuel pump internal components, leading to debris release and filter blockage in variable stator vane actuator control units. These fuel pumps have the highest risk of failure and require removal within 30 days of the effective date of this AD to prevent failure of the variable stator vane system and maintain an acceptable level of safety. The FAA considers failure of a variable stator vane system in the closed position to be an urgent safety issue that requires immediate action to avoid loss of engine thrust or in-flight engine shutdown. In addition, the compliance time for the required action is shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, 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, for the same reasons the FAA found good cause to forego notice and comment. Interim Action Comments Invited The FAA considers this AD to be an interim action. If further action is later identified, the FAA may consider additional rulemaking. The FAA invites you to send any written relevant data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2021–1072; Project Identifier MCAI–2021–01248–E’’ at the beginning of your comments. The most helpful comments reference a specific portion of the fuel pump and identifies the population of affected fuel pumps. AD Requirements This AD requires accomplishing the actions specified in EASA AD 2021– 0245, described previously, as incorporated by reference, except for any differences identified as exceptions in the regulatory text of this AD and except as discussed under ‘‘Differences Between this AD and the MCAI.’’ 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 some civil aviation authority (CAA) ADs as the primary source of information for compliance with requirements for corresponding FAA ADs. The FAA has since coordinated with other manufacturers and CAAs to use this process. As a result, EASA AD 2021–0245 will be incorporated by reference in this final rule. This AD, therefore, requires compliance with EASA AD 2021–0245 in its entirety through that incorporation, except for any differences identified as exceptions in the regulatory text of this AD. Using common terms that are the same as the heading of a particular section in EASA AD 2021–0245 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 2021–0245. Service information required by EASA AD 2021–0245 for compliance will be available at https://www.regulations.gov by searching for and locating Docket No. FAA–2021–1072. khammond on DSKJM1Z7X2PROD with RULES Differences Between This AD and the EASA AD Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 VerDate Sep<11>2014 16:14 Dec 15, 2021 Jkt 256001 PO 00000 Frm 00002 Fmt 4700 Sfmt 4700 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 (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 Nicholas Paine, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue, Burlington, MA 01803. Any commentary that the FAA receives that 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 notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects one engine installed on airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: E:\FR\FM\16DER1.SGM 16DER1 Federal Register / Vol. 86, No. 239 / Thursday, December 16, 2021 / Rules and Regulations 71369 ESTIMATED COSTS Action Labor cost Remove and replace fuel pump ..................... 4.5 work-hours × $85 per hour = $382.50 ..... Authority for This Rulemaking § 39.13 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 above, 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.

SUPPLEMENTARY INFORMATION: Background ANAC, which is the aviation authority for Brazil, has issued ANAC AD 2020–06–02R02, effective November 30, 2020 (ANAC AD 2020–06–02R02) (also referred to as the MCAI), to correct an unsafe condition for certain Yabora˜ Indu´stria Aerona´utica S.A. Model ERJ 190–100 STD, –100 LR, –100 ECJ, –100 IGW, –200 STD, –200 LR, and –200 IGW airplanes. Model 190–100 SR airplanes are not certificated by the FAA and are not included on the U.S. type certificate data sheet; this AD therefore does not include those airplanes in the applicability. The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD 2014–16–16, Amendment 39–17940 (79 FR 48018, August 15, 2014) (AD 2014–16–16); and AD 2018–19–28, Amendment 39–19429 (83 FR 48935, September 28, 2018) (AD 2018–19–28). AD 2014–16–16 applied to all Embraer S.A. Model ERJ 190–100 STD, –100 LR, –100 ECJ, –100 IGW, –200 STD, –200 LR, and –200 IGW airplanes. AD 2018–19–28 applied to certain Embraer S.A. Model ERJ 190– 100 STD, –100 LR, –100 ECJ, –100 IGW, –200 STD, –200 LR, and –200 IGW airplanes. The NPRM published in the Federal Register on August 24, 2021 (86 FR 47252). The NPRM was prompted by reports of bushing migration, loss of nut torque on the engine pylon lower inboard and outboard link fittings, a loose lower link assembly, and damaged nuts. The existing torque values could cause damage to the nuts, which could lead to loss of the shear pins of the pylon outboard and inboard lower link fittings. In addition, the existing compliance time for the modification of the pylon lower link fitting attaching parts has been found to be inadequate to address the unsafe condition. The NPRM proposed to continue to require the requirements of ADs 2014–16–16 and 2018–19–28, as specified in ANAC AD 2020–06–02R02. The NPRM also proposed to require application of a lower torque value, inspection of certain shear pins and replacement if necessary, and revised compliance times for the modification, as specified in ANAC AD 2020–06–02R02. The NPRM also proposed to prohibit the installation of affected parts. The FAA is issuing this AD to address loss of integrity of the engine pylon lower link fittings, which could lead to separation of the engine from the wing.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0245, dated November 10, 2021 
(EASA AD 2021-0245) (also referred to as the Mandatory Continuing 
Airworthiness Information, or the MCAI), to correct an unsafe condition 
on RRD RB211 Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, 
and 895-17 model turbofan engines.
    This AD was prompted by a report of single engine events that 
resulted in loss of engine thrust. An investigation by the manufacturer 
determined that certain engines were exposed to unacceptable levels of 
water contamination, which caused corrosion on the fuel pump internal 
components. This corrosion led to debris release and filter blockages 
in variable stator vane actuator control units, which resulted in the 
variable stator vane system failing in the closed position. This 
condition, if not addressed, could result in loss of engine thrust 
control, in-flight engine shutdown, and reduced control of the 
airplane. The FAA is issuing this AD to address the unsafe condition on 
these products.

FAA's Determination

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with the European Community, the FAA 
has been notified of the unsafe condition described in the MCAI. The 
FAA is issuing this AD because the agency evaluated all the relevant 
information provided by EASA and determined the safe condition 
described previously is likely to exist or develop in other products of 
the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed EASA AD 2021-0245. EASA AD 2021-0245 specifies 
instructions for replacing certain fuel pumps and identifies certain 
fuel pumps that are not to be installed on an affected engine. 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 ADDRESSES.

Other Related Service Information

    The FAA reviewed Rolls-Royce Alert Non-Modification Service 
Bulletin (NMSB) RB.211-73-AK788, dated November 9, 2021. The NMSB 
describes procedures for removing and replacing

[[Page 71368]]

the fuel pump and identifies the population of affected fuel pumps.

AD Requirements

    This AD requires accomplishing the actions specified in EASA AD 
2021-0245, described previously, as incorporated by reference, except 
for any differences identified as exceptions in the regulatory text of 
this AD and except as discussed under ``Differences Between this AD and 
the MCAI.''

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 some civil aviation 
authority (CAA) ADs as the primary source of information for compliance 
with requirements for corresponding FAA ADs. The FAA has since 
coordinated with other manufacturers and CAAs to use this process. As a 
result, EASA AD 2021-0245 will be incorporated by reference in this 
final rule. This AD, therefore, requires compliance with EASA AD 2021-
0245 in its entirety through that incorporation, except for any 
differences identified as exceptions in the regulatory text of this AD. 
Using common terms that are the same as the heading of a particular 
section in EASA AD 2021-0245 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 2021-0245. Service information 
required by EASA AD 2021-0245 for compliance will be available at 
https://www.regulations.gov by searching for and locating Docket No. 
FAA-2021-1072.

Differences Between This AD and the EASA AD

    Where EASA AD 2021-0245 requires compliance from its effective 
date, this AD requires using the effective date of this AD. This AD 
does not mandate compliance with the ``Remarks'' section of EASA AD 
2021-0245.

Interim Action

    The FAA considers this AD to be an interim action. If further 
action is later identified, the FAA may consider additional rulemaking.

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 seeking comment prior to the 
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.
    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. 
Following occurrences of single engine loss of engine thrust, the 
manufacturer determined that a subset of RRD RB211 Trent model turbofan 
engines have been exposed to unacceptable levels of water 
contamination. This water contamination may cause corrosion on the fuel 
pump internal components, leading to debris release and filter blockage 
in variable stator vane actuator control units. These fuel pumps have 
the highest risk of failure and require removal within 30 days of the 
effective date of this AD to prevent failure of the variable stator 
vane system and maintain an acceptable level of safety. The FAA 
considers failure of a variable stator vane system in the closed 
position to be an urgent safety issue that requires immediate action to 
avoid loss of engine thrust or in-flight engine shutdown. In addition, 
the compliance time for the required action is shorter than the time 
necessary for the public to comment and for publication of the final 
rule. Accordingly, notice and opportunity for prior public comment are 
impracticable and contrary to the public interest pursuant to 5 U.S.C. 
553(b)(3)(B).
    In addition, 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, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Comments Invited

    The FAA invites you to send any written relevant data, views, or 
arguments about this final rule. Send your comments to an address 
listed under ADDRESSES. Include ``Docket No. FAA-2021-1072; Project 
Identifier MCAI-2021-01248-E'' 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 (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 
Nicholas Paine, Aviation Safety Engineer, ECO Branch, FAA, 1200 
District Avenue, Burlington, MA 01803. Any commentary that the FAA 
receives that 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 notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects one engine installed on 
airplanes of U.S. registry.
    The FAA estimates the following costs to comply with this AD:

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 above, 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.
