SUPPLEMENTARY INFORMATION: AD 2022–
02–03, 39–21961 (87 FR 8402, February
15, 2022) (AD 2022–02–03), requires
independent inspection to verify reinstallation of the AGB handcranking
pad cover after maintenance. AD 2022–
02–03 also requires the replacement of
the affected AGB with a part eligible for
installation as a terminating action to
the inspection requirement.
Need for the Correction
As published, the P/Ns listed in
paragraph (i)(2)(i) of the AD, which
defines a part eligible for installation,
are incorrect. The P/Ns were incorrectly
listed as 340–046–503–0, 340–046–504–
0, and 340–046–505–0. The correct P/Ns
are 335–300–103–0, 335–300–105–0,
335–300–106–0, 335–300–107–0, 335–
300–108–0, 335–300–109–0, and 335–
300–110–0.
Although no other part of the
preamble or regulatory information has
been corrected, for clarity, the FAA is
publishing the entire rule in the Federal
Register.
The effective date of this AD remains
March 22, 2022.
Good Cause for Adoption Without Prior
Notice
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
PO 00000
Frm 00015
Fmt 4700
Sfmt 4700
11289
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 this action corrects
P/Ns that were correctly identified in a
notice of proposed rulemaking, which
published in the Federal Register on
May 3, 2021 (86 FR 23301).
Accordingly, notice and opportunity for
prior public comment are unnecessary
pursuant to 5 U.S.C. 553(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.

SUPPLEMENTARY INFORMATION: AD 2022-02-03, 39-21961 (87 FR 8402,
February 15, 2022) (AD 2022-02-03), requires independent inspection to
verify re-installation of the AGB handcranking pad cover after
maintenance. AD 2022-02-03 also requires the replacement of the
affected AGB with a part eligible for installation as a terminating
action to the inspection requirement.
Need for the Correction
As published, the P/Ns listed in paragraph (i)(2)(i) of the AD,
which defines a part eligible for installation, are incorrect. The P/Ns
were incorrectly listed as 340-046-503-0, 340-046-504-0, and 340-046-
505-0. The correct P/Ns are 335-300-103-0, 335-300-105-0, 335-300-106-
0, 335-300-107-0, 335-300-108-0, 335-300-109-0, and 335-300-110-0.
Although no other part of the preamble or regulatory information
has been corrected, for clarity, the FAA is publishing the entire rule
in the Federal Register.
The effective date of this AD remains March 22, 2022.
Good Cause for Adoption Without Prior Notice
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
this action corrects P/Ns that were correctly identified in a notice of
proposed rulemaking, which published in the Federal Register on May 3,
2021 (86 FR 23301). Accordingly, notice and opportunity for prior
public comment are unnecessary pursuant to 5 U.S.C. 553(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.
