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 
Vladimir Ulyanov, Aerospace Engineer, Large Aircraft Section, FAA, 
International Validation Branch, 2200 South 216th St., Des Moines, WA

Any commentary that the FAA receives which is not specifically 
designated as CBI will be placed in the public docket for this 
rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0210, dated September 16, 2021 
(EASA AD 2021-0210) (also referred to as the MCAI), to correct an 
unsafe condition for all Airbus SAS Model A330-841 and A330-941 
airplanes.
    This AD was prompted by a report of incorrect take-off computations 
for crosswinds above 20 knots in a certain AFM. The FAA is issuing this 
AD to address substantially reduced take-off performance in crosswind 
conditions above 20 knots, possibly resulting in a runway overrun, in 
the event of continued takeoff following an engine failure or a 
rejected takeoff, with consequent damage to the airplane and injury to 
occupants. See the MCAI for additional background information.

Related Service Information Under 1 CFR Part 51

    EASA AD 2021-0210 specifies procedures for amending the existing 
AFM to include revised aircraft performance databases for performance 
calculations for crosswind above 20 knots. 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

    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 of the 
unsafe condition described in the MCAI described above. The FAA is 
issuing this AD after determining that the unsafe condition described 
previously is likely to exist or develop on other products of these 
same type designs.

Requirements of This AD

    This AD requires accomplishing the actions specified in EASA AD 
2021-0210 described previously, except for any differences identified 
as exceptions in the regulatory text of this AD.
    EASA AD 2021-0210 requires operators to ``inform all flight crews'' 
of revisions to the AFM, and thereafter to ``operate the aeroplane 
accordingly.'' However, this AD would not specifically require those 
actions as those actions are already required by FAA regulations. FAA 
regulations require operators to furnish to pilots any changes to the 
AFM (for example, 14 CFR 121.137), and to ensure that the pilots are 
familiar with the AFM (for example, 14 CFR 91.505). As with any other 
flightcrew training requirement, training on the updated AFM content is 
tracked by the operators and recorded in each pilot's training record, 
which is available for the FAA to review. FAA regulations also require 
pilots to follow the procedures in the existing AFM including all 
updates. 14 CFR 91.9 requires that any person operating a

[[Page 57554]]

civil aircraft must comply with the operating limitations specified in 
the AFM.

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 been 
coordinating this process with manufacturers and CAAs. As a result, 
EASA AD 2021-0210 is incorporated by reference in this AD. This AD 
requires compliance with EASA AD 2021-0210 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 2021-0210 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 
2021-0210. Service information required by EASA AD 2021-0210 for 
compliance will be available at https://www.regulations.gov by 
searching for and locating Docket No. FAA-2021-0876 after this AD is 
published.

FAA's Justification 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 incorrect take-off computations for crosswinds above 20 knots 
could result in substantially reduced take-off performance in those 
conditions, possibly resulting in a runway overrun, in the event of 
continued takeoff following an engine failure or rejected takeoff, with 
consequent damage to the airplane and injury to occupants. 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.

Regulatory Flexibility Act (RFA)

    The requirements of the 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 11 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.

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, European Union Aviation Safety Agency (EASA) AD 
2021-0210, dated September 16, 2021 (EASA AD 2021-0210).

(h) Exceptions to EASA AD 2021-0210

    (1) Where EASA AD 2021-0210 refers to its effective date, this 
AD requires using the effective date of this AD.
    (2) Where paragraph (1) of EASA AD 2021-0210 specifies amending 
the aircraft flight manual (AFM), this AD requires replacing the 
text ``implement the aircraft performance database by introducing 
the AFM DU [Documentary Unit]'' with ``amend the applicable existing 
AFM and applicable corresponding operational procedures by 
incorporating the AFM DU.''
    (3) Whereas paragraph (1) of EASA AD 2021-0210 specifies to 
``inform all flight crews, and, thereafter, operate the aeroplane 
accordingly,'' this AD does not require those actions as those 
actions are already required by existing FAA operating regulations.
