Abstract
The FAA is correcting an airworthiness directive (AD) that published in the Federal Register. The AD applies to CFM International, S.A. CFM56-3 and CFM56-7B model turbofan engines with certain accessory gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in the handcranking pad. As published, the part numbers (P/Ns) listed in paragraph (i)(2)(i) are incorrect. This document corrects that error. In all other respects, the original document remains the same; however, for clarity, the FAA is publishing the entire rule in the Federal Register.

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; correction.
-----------------------------------------------------------------------
SUMMARY: The FAA is correcting an airworthiness directive (AD) that
published in the Federal Register. The AD applies to CFM International,
S.A. CFM56-3 and CFM56-7B model turbofan engines with certain accessory
gearbox assembly (AGB) not equipped with a dynamic oil seal assembly in
the handcranking pad. As published, the part numbers (P/Ns) listed in
paragraph (i)(2)(i) are incorrect. This document corrects that error.
In all other respects, the original document remains the same; however,
for clarity, the FAA is publishing the entire rule in the Federal
Register.
DATES: This correction is effective March 22, 2022. The effective date

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.

(e) Unsafe Condition
This AD was prompted by a dual engine loss of oil event and 42
prior events of total loss of engine oil during flight. The FAA is
issuing this AD to prevent loss of engine oil while in flight. The
unsafe condition, if not addressed, could result in engine failure,
loss of thrust control, reduced control of the aircraft, and damage
to the airplane.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Required Actions
(1) After the effective date of this AD, after any maintenance
that involves removal and re-installation of the AGB handcranking
pad cover, perform an independent inspection to verify re-
installation of the AGB handcranking pad cover; or
(2) Prior to the next removal of the AGB handcranking pad cover
from the engine, insert the independent inspection required by
paragraph (g)(1) of this AD as a required inspection item in the
existing approved continuous airworthiness maintenance program for
the aircraft.
(h) Mandatory Terminating Action
As a mandatory terminating action to the requirements of
paragraph (g) of this AD:
(1) For affected CFM56-3, CFM56-3B, and CFM56-3C model turbofan
engines, at the next engine shop visit, or before December 31, 2026,
whichever occurs first after the effective date of this AD, replace
the affected AGB with a part eligible for installation.
(2) For affected CFM56-7B model turbofan engines, except for
CFM56-7B27A, CFM56-7B27A/3, and CFM56-7B27AE model turbofan engines,
at the next engine shop visit, or before December 31, 2024,
whichever occurs first after the effective date of this AD, replace
the affected AGB with a part eligible for installation.
(i) Definition
(1) For the purpose of this AD, an ``engine shop visit'' is the
induction of an engine into the shop for maintenance involving the

the following situations, which do not constitute an engine shop
visit:
(i) Separation of engine flanges solely for the purposes of
transportation of the engine without subsequent maintenance; or
(ii) Separation of engine flanges solely for the purpose of
replacing the fan or propulsor without subsequent maintenance.
(2) For the purpose of this AD, for affected CFM56-3, CFM56-3B,
