General Electric Company (GE) GE Passport 20-17BB1A, GE Passport 20-
18BB1A, and GE Passport 20-19BB1A model turbofan engines. This AD was
prompted by fuel leakage from the fuel nozzle to fuel manifold coupling
nut connections. This AD requires a visual inspection of the core
compartment, a re-torque of the core compartment coupling nuts, a
ground power assurance check, and a borescope

inspection. Depending on the results of the inspections, this AD
requires operators to perform applicable maintenance in accordance with
their FAA-approved instructions for continued airworthiness. The FAA is
issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION:

Background

    On March 31, 2022, and April 4, 2022, two Bombardier Inc. BD-700-
2A12 airplanes (marketed as Global 7500 airplanes), powered by GE
Passport P20-19BB1A and GE Passport P20-18BB1A model turbofan engines,
respectively, experienced an engine fire during flight. The engine fire
on the GE Passport P20-19BB1A resulted in a commanded in-flight
shutdown (IFSD) and air turnback (ATB). The engine fire on the GE
Passport P20-18BB1A resulted in an ATB. A subsequent investigation by
the manufacturer found evidence of fuel leakage on the lower outboard
core panel, aft end of the bifi plate, ignition lead, and fuel manifold
B-nut connections. The investigation also found that fuel nozzle to
fuel manifold B-nut connections were under-torqued on both event
engines and the fuel leak at the fuel nozzle B-nut connections likely
caused the engine fires. As a result, the manufacturer published GE
Service Bulletin (SB) PASSPORT20-A-72-00-0141-00A-930A-D, Issue No 000,
dated April 12, 2022, and GE SB PASSPORT20-A-72-00-0142-00A-930A-D,
Issue No 001, dated May 11, 2022. The service information specifies
procedures for the performance of a visual inspection of the fuel
nozzle zone in the core compartment for indications of fuel leakage,
undetected fire, or heat distress, re-torque of the coupling nuts in
the core compartment, a ground power assurance check, and a borescope
inspection. This condition, if not addressed, could result in engine
fire, failure of the engine, in-flight shutdown, and loss of the
airplane. The FAA is issuing this AD to address the unsafe condition on
these products.

FAA's Determination

    The FAA is issuing this AD because the agency has determined the
unsafe condition described previously is likely to exist or develop in
other products of the same type design.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed GE SB PASSPORT20-A-72-00-0142-00A-930A-D, Issue No
001, dated May 11, 2022 (GE SB PASSPORT20-A-72-00-0142). GE SB
PASSPORT20-A-72-00-0142 specifies procedures for the performance of a
visual inspection, a re-torque of the coupling nuts in the core
compartment, a ground power assurance check, and a borescope
inspection. 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.

Other Related Service Information

    The FAA reviewed GE SB PASSPORT20-A-72-00-0141-00A-930A-D, Issue No
000, dated April 12, 2022 (GE SB PASSPORT20-A-72-00-0141). GE SB
PASSPORT20-A-72-00-0141 specifies procedures for the performance of a
borescope inspection of the core compartment for indications of fuel
leak or fire.

AD Requirements

    This AD requires a visual inspection of the core compartment, re-
torque of the core compartment coupling nuts, a ground power assurance
check, and a borescope inspection. Depending on the results of the
inspections, this AD requires operators to perform applicable
maintenance in accordance with their FAA-approved instructions for
continued airworthiness.

Differences Between the AD and the Service Information

    GE SB PASSPORT20-A-72-00-0142-00A-930A-D specifies procedures for
reporting information to the manufacturer. This AD does not require
operators to report information to the manufacturer.
    GE SB PASSPORT20-A-72-00-0142-00A-930A-D specifies procedures for
contacting a GE field service engineer or 24/7 Business Aviation
Support. This AD does not require operators to contact a GE field
service engineer or 24/7 Business Aviation Support. Instead, this AD
requires following an FAA-approved method to return the engine to
service.

Interim Action

    The FAA considers this AD to be an interim action. This unsafe
condition is still under investigation by the manufacturer and,
depending on the results of that investigation, the FAA may consider
further rulemaking action.

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.
The FAA considers fuel leakage and engine fire to be an urgent safety
issue. The visual inspection of the core compartment is necessary to
prevent engine fire, IFSD, damage to the airplane, failure of the
engine, and loss of control of the airplane. All GE Passport 20-17BB1A,
Passport 20-18BB1A, and Passport 20-19BB1A model turbofan engines are
equipped with fuel nozzle to fuel manifold coupling nut connections
which were determined by the manufacturer to have the potential for
under-torqueing, following two incidents of engine fire on airplanes
wherein a fuel leak at the fuel nozzle coupling nut connection was
likely the cause of the fire. Affected engines must undergo a visual
inspection before exceeding 30, 50, or 75 flight cycles (FCs) after the
effective date of this AD, depending on the engine's cycles since new
(CSN). Re-torque of the core compartment coupling nuts is required
within 30 or 100 FCs after the effective date of the AD, depending on
the engine serial number. Current fleet utilization data estimates the
flight cycles will be accumulated between 30 and 90 days after the
effective date of this AD. For affected engines with indications of
fuel leakage, undetected fire, or heat distress following a visual
inspection of the core compartment, this AD requires operators to
perform applicable maintenance in accordance with their FAA-approved
instructions for continued airworthiness. 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-2022-0691 and Project Identifier
AD-2022-00601-E'' 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 Scott
Stevenson, Aviation Safety Engineer, ECO Branch, FAA, 1200 District
Avenue, Burlington, MA 01803. Any commentary that the FAA receives
which is not specifically designated as CBI will be placed in the
public docket for this rulemaking.

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 42 engines installed on
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.
