Airworthiness Directives; The Boeing Company Airplanes
Publication summary
The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model 767-2C series airplanes. This AD was prompted by a report of multiple nuisance caution "RECIRC SMOKE" engine indication and crew alerting system (EICAS) messages that may occur when water accumulates in the alternative ventilation system (AVS) duct. This AD requires replacing the alternative ventilation duct having a certain part number with a new part number, and for certain airplanes, changing the insulation blanket to install the drain hose. This AD also prohibits the installation of an alternative ventilation duct, part number (P/N) 216T2101-704, on any airplane. The FAA is issuing this AD to address the unsafe condition on these products.

Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
The Boeing Company Model 767-2C series airplanes. This AD was prompted
by a report of multiple nuisance caution ``RECIRC SMOKE'' engine
indication and crew alerting system (EICAS) messages that may occur
when water accumulates in the alternative ventilation system (AVS)
duct. This AD requires replacing the alternative ventilation duct
having a certain part number with a new part number, and for certain
airplanes, changing the insulation blanket to install the drain hose.
This AD also prohibits the installation of an alternative ventilation
duct, part number (P/N) 216T2101-704, on any airplane. The FAA is
issuing this AD to address the unsafe condition on these products.
DATES: This AD is effective April 18, 2022.
The FAA must receive comments on this AD by May 16, 2022.
ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:
Background
The FAA has received a report indicating multiple nuisance caution
``RECIRC SMOKE'' EICAS messages that may occur when water accumulates
in the AVS duct. The AVS duct is at a lower position than the
recirculation smoke detector tubing, and therefore, there is a
potential for water to leak onto the AVS duct. Water accumulation in
the AVS duct can block AVS system airflow into the airplane, creating a
loss of conditioned inflow and result in cold or hot flight deck
temperatures. This condition, if not addressed, could affect the
flightcrew's ability to maintain continued safe flight and landing. 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.
AD Requirements
This AD requires replacing the alternative ventilation duct having
P/N 216T2101-704 with new P/N 216T2101-707, and for certain airplanes,
changing the insulation blanket to install the drain hose. This AD also
prohibits the installation of an alternative ventilation duct, P/N
216T2101-704, on any airplane.
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.
There are currently no U.S.-registered airplanes affected by this
AD. Accordingly, notice and opportunity for prior public comment are
unnecessary, pursuant to 5 U.S.C. 553(b)(3). In addition, for the
foregoing reason(s), 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.
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-2022-0280 and Project Identifier AD-
2021-00504-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
[[Page 18982]]
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 Brandon
Lucero, Aerospace Engineer, Cabin Safety and Environmental Systems
Section, FAA, Seattle ACO Branch, 2200 South 216th St., Des Moines, WA
98198; phone and fax: 206-231-3569; email: [email protected]. Any
commentary that the FAA receives that 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 notice and comment,
RFA analysis is not required.
Costs of Compliance
Currently, there are no affected U.S.-registered airplanes. For any
affected airplane that is imported and placed on the U.S. Register in
the future, the FAA provides the following cost estimates to comply
with this AD:
Estimated Costs *
----------------------------------------------------------------------------------------------------------------
Action Labor cost Parts cost Cost per product
----------------------------------------------------------------------------------------------------------------
Replacement and drain hose Up to 5 work-hour x $85 Up to $5,490............ Up to $5,915.
installation. per hour = $425.
----------------------------------------------------------------------------------------------------------------
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.
