SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued a series of ADs, the most recent being EASA 
AD 2021-0185R1, dated August 11, 2021 (EASA AD 2021-0185R1), to correct 
an unsafe condition for Umlaut Engineering GmbH, formerly P3 
Engineering GmbH, fire extinguishers, having part number (P/N) 
P3APP003010A, P/N P3APP003010B, or P/N P3APP003010C. EASA advises of a 
safety issue that has been reported on the affected fire extinguishers 
where certain environmental conditions may prohibit discharge of the 
fire extinguisher. An investigation has determined that prolonged 
exposure to high temperature conditions can dislodge the spindle in the 
fire extinguisher head, subsequently making the fire extinguisher 
inoperative. This condition, if not addressed, could prevent proper 
extinguishing of a fire in the cabin or cockpit, possibly resulting in 
damage to the aircraft and injury to the occupants.
    Initially, EASA issued EASA AD 2021-0185, dated August 5, 2021 
(EASA AD 2021-0185), which required repetitive inspections of each 
affected

[[Page 60558]]

fire extinguisher, and, depending on findings, replacement with a 
serviceable part, as identified in EASA AD 2021-0185. EASA AD 2021-0185 
also required inspection of an affected fire extinguisher prior to the 
return to service of an aircraft with an affected part installed if the 
aircraft had been parked or stored for a period of 30 days or more. 
EASA AD 2021-0185 also required inspection of an affected fire 
extinguisher prior to installation on any aircraft.
    EASA later issued EASA AD 2021-0185R1 to revise EASA AD 2021-0185. 
EASA AD 2021-0185R1 contains the same requirements, clarifies some 
nomenclature, removes the Group definitions and references, and adds 
Note 3 to clarify the parts prohibition.

FAA's Determination

    These products 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 products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Umlaut Vendor Service Bulletin (VSB) Doc. No. 
P3VSB000003, Issue C, dated August 3, 2021 (VSB P3VSB000003, Issue C). 
This service information specifies procedures for identifying affected 
fire extinguishers with P/N P3APP003010A, P3APP003010B, or 
P3APP003010C. VSB P3VSB000003, Issue C, also specifies procedures for 
inspecting and depending on the results, replacing affected fire 
extinguishers.
    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.

Other Related Service Information

    The FAA also reviewed Umlaut VSB Doc. No. P3VSB000003, Issue A, 
dated May 10, 2021 (VSB P3VSB000003, Issue A), and Issue B, dated July 
14, 2021 (VSB P3VSB000003, Issue B). VSB P3VSB000003, Issue A, and VSB 
P3VSB000003, Issue B, specify the same procedures as VSB P3VSB000003, 
Issue C, except VSB P3VSB000003, Issue B updated the introductory 
information of the Accomplishment Instructions, revised the 
determination/evaluation of the aircraft/equipment history procedures, 
and clarified reporting procedures; and VSB P3VSB000003, Issue C, adds 
more in-depth inspection procedures.

AD Requirements

    This AD requires within 30 days after the effective date of this 
AD, and thereafter at intervals not to exceed 6 months, repetitively 
inspecting an affected fire extinguisher and depending on the results, 
removing the fire extinguisher from service. For an affected fire 
extinguisher that is installed on any aircraft that has not been in 
operation for 30 or more consecutive days, or if it cannot be 
determined how long an aircraft has not been in operation, this AD 
requires those actions before further flight and thereafter at 
intervals not to exceed 6 months. This AD also prohibits installing, as 
a replacement part or as an original installation, an affected fire 
extinguisher on any aircraft unless it passes the required inspections.

Differences Between This AD and the EASA AD

    If it cannot be determined how long an aircraft (with an affected 
fire extinguisher installed) has not been in operation, this AD 
requires inspecting each affected fire extinguisher before further 
flight, whereas EASA AD 2021-0185R1 does not.

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.
    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 foregoing notice and comment prior to adoption of this rule 
because the initial inspection of the fire extinguisher must be 
accomplished within 30 days after the effective date of this AD. 
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 data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0882; Project Identifier MCAI-
2021-00929-Q'' 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 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.

[[Page 60559]]

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

    The FAA estimates that this AD affects up to 2,850 fire 
extinguishers installed on aircraft of U.S. registry. Labor rates are 
estimated at $85 per work-hour. Based on these numbers, the FAA 
estimates the following costs to comply with this AD.
    Inspecting an affected fire extinguisher would take about 0.25 
work-hour for an estimated cost of $21 per fire extinguisher, and up to 
$59,850 for the U.S. fleet, per inspection cycle. Replacing an affected 
fire extinguisher would take about 0.25 work-hour and parts would cost 
about $1,200 for an estimated cost of $1,221 per fire extinguisher.

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.
