SUPPLEMENTARY INFORMATION: 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. To address this unsafe condition, AERO issued [mandatory service bulletin] MSB EPB.01.B to provide inspection instructions for certain propellers, and EASA issued Emergency AD 2009–0134–E to require repetitive detailed visual inspections of those propeller hubs and, depending on findings, replacement. Since that [EASA] AD was issued, additional occurrences were reported of finding propeller hub cracks. Prompted by these findings, AERO issued MSB EPB.02.B applicable to propellers with s/n 3E.089 and higher. For the reason described above, this [EASA] AD retains the requirements of EASA Emergency AD 2009–0134–E, which is superseded, and expands the Applicability to all propeller s/n. Confidential Business Information CBI is commercial or financial information that is both customarily and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 Doug Rudolph, Aviation Safety Engineer, FAA, General Aviation & Rotorcraft Section, International Validation Branch, 901 Locust, Room 301, Kansas City, MO 64106. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. You may examine the MCAI in the AD docket at https:// www.regulations.gov by searching for and locating Docket No. FAA–2021– 0782. Comments Invited Background The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0189–E, dated August 9, 2021 (referred to after this as ‘‘the MCAI’’), to address an unsafe condition on ELPROP 3–1–1P propellers that are installed on, but not limited to, AERO Models AT– 3R100 and AT–4LSA airplanes. The MCAI states: 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–2021–0782 and Project Identifier MCAI–2021– 00915–A’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final Occurrences have been reported of finding cracks on the propeller hub during service inspections. Cracks were detected on the propeller hub surface, near the blade attachment bolt holes and in the blade root area. This condition, if not detected and corrected, could lead to loss of the propeller blade with consequent loss of control of the aeroplane.

This service information specifies procedures for inspecting the propeller hub for cracks and contacting the design approval holder for corrective action. 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 ADDRESSES. 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 this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD because it has determined the unsafe condition described previously is likely to exist or develop on other products of the same type design. AD Requirements This AD requires accomplishing the actions specified in the service information already described. Differences Between This AD and the MCAI The MCAI applies to the Model AT– 4LSA airplane, and this AD does not E:\FR\FM\07OCR1.SGM 07OCR1 Federal Register / Vol. 86, No. 192 / Thursday, October 7, 2021 / Rules and Regulations because it does not have an FAA type certificate. 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. The FAA has found that the risk to the flying public justifies foregoing notice and comment prior to adoption of this rule because there are no airplanes currently on the U.S. registry and thus, it is unlikely that the FAA will receive any adverse comments or useful information about this AD from U.S. operators. Accordingly, notice and opportunity for prior public comment are unnecessary 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. Costs of Compliance There are currently no affected airplanes on the U.S. registry. In the event an affected airplane becomes a U.S. registered airplane, the following is an estimate of the costs to comply with this AD. The FAA estimates that it would take .5 work-hour per airplane to comply with the inspection requirement in this AD. The average labor rate is $85 per work-hour. Based on these figures, the FAA estimates the cost of this AD to be $42.50 per airplane, per inspection cycle. Corrective action if cracks are found would vary significantly from airplane to airplane. Therefore, the FAA is unable to estimate what the cost of corrective action would be per airplane. lotter on DSK11XQN23PROD with RULES1 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 VerDate Sep<11>2014 16:21 Oct 06, 2021 Jkt 256001 55687 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. 2021–19–14 AERO Sp. z o.o.: Amendment 39–21732; Docket No. FAA–2021–0782; Project Identifier MCAI–2021–00915–A. Regulatory Flexibility Act (e) Unsafe Condition This AD was prompted by mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI identifies the unsafe condition as cracks in the propeller hub. The FAA is issuing this AD to detect and correct cracked propeller hubs, which could lead to loss of the propeller blade with consequent loss of airplane control. 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 FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. 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: SUMMARY: Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that PO 00000 Frm 00004 Fmt 4700 Sfmt 4700 section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it revokes the Class E airspace at Creech AFB Airport, Indian Springs, NV, to ensure the safety and management of operations at the airport. History The FAA published a notice of proposed rulemaking in the Federal Register (86 FR 40790; July 29, 2021) for Docket No. FAA–2021–0591 to revoke the Class E airspace at Creech AFB Airport, Indian Springs, NV. Interested parties were invited to participate in this rulemaking effort by submitting written comments on the proposal to the FAA. Two comments were received. One comment is in favor of the Class E airspace revocation and the other comment is opposed to the airspace revocation. The commenter who opposes the Class E revocation discussed concerns about the airspace’s future use. Class E airspace areas, extending upward from 700 feet or more above the surface of the earth, are designated for airports with approved instrument approach procedure. Creech AFB Airport does not have approved instrument approach procedures, as such, the Class E airspace is being revoked. If the airport develops instrument procedures, the FAA will reevaluate the airspace to ensure containment of the instrument procedures. Class D and Class E5 airspace designations are published in paragraphs 5000, and 6005, respectively, of FAA Order JO 7400.11F, dated August 10, 2021, and effective September 15, 2021, which is incorporated by reference in 14 CFR 71.1. The Class E airspace designation listed in this document will be published subsequently in the Order. Availability and Summary of Documents for Incorporation by Reference This document amends FAA Order JO 7400.11F, Airspace Designations and Reporting Points, dated August 10, 2021, and effective September 15, 2021. FAA Order JO 7400.11F is publicly available as listed in the ADDRESSES section of this document. FAA Order JO 7400.11F lists Class A, B, C, D, and E airspace areas, air traffic service routes, and reporting points.

Background

    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Union, has issued 
EASA AD 2021-0189-E, dated August 9, 2021 (referred to after this as 
``the MCAI''), to address an unsafe condition on ELPROP 3-1-1P 
propellers that are installed on, but not limited to, AERO Models AT-
3R100 and AT-4LSA airplanes. The MCAI states:

    Occurrences have been reported of finding cracks on the 
propeller hub during service inspections. Cracks were detected on 
the propeller hub surface, near the blade attachment bolt holes and 
in the blade root area.
    This condition, if not detected and corrected, could lead to 
loss of the propeller blade with consequent loss of control of the 
aeroplane.
    To address this unsafe condition, AERO issued [mandatory service 
bulletin] MSB EPB.01.B to provide inspection instructions for 
certain propellers, and EASA issued Emergency AD 2009-0134-E to 
require repetitive detailed visual inspections of those propeller 
hubs and, depending on findings, replacement.
    Since that [EASA] AD was issued, additional occurrences were 
reported of finding propeller hub cracks. Prompted by these 
findings, AERO issued MSB EPB.02.B applicable to propellers with s/n 
3E.089 and higher.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA Emergency AD 2009-0134-E, which is superseded, 
and expands the Applicability to all propeller s/n.

    You may examine the MCAI in the AD docket at https://www.regulations.gov by searching for and locating Docket No. FAA-2021-
0782.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed AERO Mandatory Service Bulletin (MSB) EPB.01.B, 
Issue 1, dated May 14, 2009, which applies to propellers with serial 
numbers 3E.001 through 3E.088; and AERO MSB EPB.02.B, Issue 1, dated 
July 20, 2021, which applies to propellers with serial numbers 3E.089 
and larger. This service information specifies procedures for 
inspecting the propeller hub for cracks and contacting the design 
approval holder for corrective action. 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 
ADDRESSES.

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 this State of Design Authority, 
it has notified the FAA of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is issuing this AD 
because it has determined the unsafe condition described previously is 
likely to exist or develop on other products of the same type design.

AD Requirements

    This AD requires accomplishing the actions specified in the service 
information already described.

Differences Between This AD and the MCAI

    The MCAI applies to the Model AT-4LSA airplane, and this AD does 
not

[[Page 55687]]

because it does not have an FAA type certificate.

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.
    The FAA has found that the risk to the flying public justifies 
foregoing notice and comment prior to adoption of this rule because 
there are no airplanes currently on the U.S. registry and thus, it is 
unlikely that the FAA will receive any adverse comments or useful 
information about this AD from U.S. operators. Accordingly, notice and 
opportunity for prior public comment are unnecessary 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.

Costs of Compliance

    There are currently no affected airplanes on the U.S. registry. In 
the event an affected airplane becomes a U.S. registered airplane, the 
following is an estimate of the costs to comply with this AD.
    The FAA estimates that it would take .5 work-hour per airplane to 
comply with the inspection requirement in this AD. The average labor 
rate is $85 per work-hour. Based on these figures, the FAA estimates 
the cost of this AD to be $42.50 per airplane, per inspection cycle.
    Corrective action if cracks are found would vary significantly from 
airplane to airplane. Therefore, the FAA is unable to estimate what the 
cost of corrective action would be per airplane.

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 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 FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

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.
