SUPPLEMENTARY INFORMATION:
Background
The Civil Aviation Authority of Israel (CAAI), which is the
aviation authority for Israel, has issued Israeli AD ISR-I-24-2021-6-
6R1, dated June 27, 2021 (also referred to after this as the Mandatory
Continuing Airworthiness Information, or the MCAI), to correct an
unsafe condition for The Boeing Company Model 767-300 series airplanes,
that have been modified to a Bedek Division Special Freighter (BDSF),
designated as 767-300BDSF, in accordance with CAAI STC SA218/FAA STC
ST02040SE/European Union Aviation Safety Agency (EASA) STC 10028430 (as
listed in the appendix of the MCAI). Only FAA STC ST02040SE is approved
for U.S. operators. You may examine the MCAI on the internet at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating Docket No. FAA-2021-
0566.
This AD was prompted by a report that the electrical diagram for
the C9066 circuit breaker connection (wiring) for the ``Main Deck
Oxygen Alert Control'' is erroneous and might have resulted in
[[Page 37020]]
incorrect installation. This incorrect installation leads to an
unprotected circuit, and therefore any wires or system components that
might lie adjacent to the wiring that would normally be protected by
the C9066 circuit breaker might be affected. The FAA is issuing this AD
to address potential incorrect installation of the ``Main Deck Oxygen
Alert Control'' circuit breaker, which could result in overheating and
burning of the wiring, and consequently, could result in smoke
triggering an alarm and causing the crew workload to increase; or could
result in a short circuit to adjacent wires causing malfunctions in
other systems. See the MCAI for additional background information.
Related Service Information Under 1 CFR Part 51
Israel Aerospace Industries, Ltd., has issued IAI-Aviation Group
Alert Service Bulletin 368-24-098, Revision 1, dated June 2021. This
service information describes procedures for a visual inspection of the
wiring connection common to the C9066 circuit breaker, changes to the
wiring connection, if necessary, and a test of the main deck oxygen
alert system, if necessary. 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.
FAA's Determination
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to the FAA's bilateral agreement with the State of Design Authority,
the FAA has been notified of the unsafe condition described in the MCAI
and service information referenced above. The FAA is issuing this AD
because the FAA evaluated all pertinent information and determined the
unsafe condition exists and is likely to exist or develop on other
products of the same type design.
Requirements of This AD
This AD requires accomplishing the actions specified in the service
information described previously.
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 forgoing notice and comment prior to adoption of this rule
because incorrect installation of the ``Main Deck Oxygen Alert
Control'' circuit breaker could result in overheating and burning of
wiring, and consequently, could result in smoke triggering an alarm and
causing the crew workload to increase; or could result in a short
circuit to adjacent wires causing malfunctions in other systems.
Furthermore, since this is a potentially unprotected circuit, if any
failure occurs along the length of this circuit it could result in a
fire and cause collateral damage to adjacent circuits and affect
critical systems necessary for continued safe flight and landing.
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 forgo
notice and comment.
Comments Invited
The FAA invites you to send any written relevant data, views, or
arguments about this AD. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2021-0566; Project Identifier MCAI-
2021-00733-T'' 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
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, 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 Brian
Hernandez, Aerospace Engineer, Systems and Equipment Section, FAA,
Seattle ACO Branch, 2200 South 216th St., Des Moines, WA 98198; phone
and fax: 206-231-3535; email: <a href="/cdn-cgi/l/email-protection#b7f5c5ded6d999ffd2c5d9d6d9d3d2cdf7d1d6d699d0d8c1"><span class="__cf_email__" data-cfemail="4a0838232b2464022f38242b242e2f300a2c2b2b642d253c">[email protected]</span></a>. 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 (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 71 airplanes of U.S.
registry. The FAA estimates the following costs to comply with this AD:
[[Page 37021]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection............................ 1 work-hour x $85 per $0 $85 $6,035
hour = $85.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of the
inspection. The FAA has no way of determining the number of aircraft
that might need these actions:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per

----------------------------------------------------------------------------------------------------------------
Wiring change and test........................ 1 work-hour x $85 per hour = $85 $0 $85
----------------------------------------------------------------------------------------------------------------
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
The FAA determined that 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.
List of Subjects in 14 CFR Part 39

Oxygen Alert Control'' is erroneous and might have resulted in
incorrect installation. The FAA is issuing this AD to address
potential incorrect installation of the ``Main Deck Oxygen Alert
Control'' circuit breaker, which could result in overheating and
burning of the wiring, and consequently, could result in smoke
triggering an alarm and causing the crew workload to increase; or
could result in a short circuit to adjacent wires causing
malfunctions in other systems. Furthermore, since this is a
potentially unprotected circuit, if any failure occurs along the
length of this circuit it could result in a fire and cause
collateral damage to adjacent circuits and affect critical systems
necessary for continued safe flight and landing.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Inspection, Wiring Connection Change, and Test
Within 10 days after the effective date of this AD, perform a
