Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 767-300 series airplanes modified by a certain supplemental type certificate (STC). This proposed AD was prompted by a discovery that certain pitot-static tubing of the first officer's pitot-static system was installed incorrectly in the main and mid equipment center during the airplane conversion from passenger to freighter. This proposed AD would require a visual inspection of certain pitot-static rigid tubes and flexible hoses to determine whether low points exist, and if necessary, related investigative and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.

Background
The Civil Aviation Authority of Israel (CAAI), which is the
aviation authority for Israel, has issued CAAI AD ISR I-34-2024-07-1,
dated August 6, 2024 (CAAI AD ISR I-34-2024-07-1) (also referred to
after this as the MCAI), to correct an unsafe condition for The Boeing
Company Model 767-300 series airplanes, that have been modified to
freighters, in accordance with CAAI STC SA-218 (FAA STC ST02040SE, EASA
STC 10028430, CAAC VSTC0812, TCCA SA14-67, ANAC 2011S03-12). Only FAA
STC ST02040SE is approved for U.S. operators. The MCAI states that due
to the pitot-static tubing improper rerouting on the airplane
conversion from passenger to freighter, two erroneous conditions were
found in the tubing connecting the pitot and the static system tubing
to the right air data computer belonging to the first officer system:
The flexible hoses part number (P/N) BACH30BC06-0097 and P/N
BACH30BC05-0111, creating a potential water trap; and rigid tubes P/N
233T9110-437 and P/N 233T9110-320/314 installed through a structure 9G
rigid barrier opening, creating a potential water trap.
The FAA is proposing this AD to address the incorrect installation
of the pitot-static tubing of the first officer's pitot-static system.
The unsafe conditions, if not addressed, may affect the capability to
drain water or moisture collected in the first officer pitot-static
tubing, and may cause malfunction to the system.
You may examine the MCAI in the AD docket at <a href="http://regulations.gov">regulations.gov</a> under
Docket No. FAA-2024-2662.
Material Incorporated by Reference Under 1 CFR Part 51
The FAA reviewed Israel Aerospace Industry Ltd., Service Bulletin
368-34-106, dated August 2024. This material specifies procedures for a
visual inspection of the pitot-static rigid tubes, P/N 233T9110-437 and
P/N 233T9110-314, and the flexible hoses, P/N BACH30BC06-0097 and P/N
BACH30BC05-0111, to determine whether low points exist, and related
investigative and corrective actions. The related investigative action
is a visual inspection for the installation of the provisions located
above the right miscellaneous electrical equipment panel (P37). The
corrective actions include replacement of the pitot and the static
system tubing connected to the right air data computer, including
installation of standoffs, rigid tubes, union fitting, elbow fitting,
flexible hoses, and performing functional tests.
This material 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
[[Page 102021]]
country and is approved for operation in the United States. Pursuant to
the FAA's bilateral agreement with this State of Design Authority, it
has notified the FAA of the unsafe condition described in the MCAI and
material referenced above. The FAA is issuing this NPRM after
determining that the unsafe condition described previously is likely to
exist or develop on other products of the same type design.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in the material already described.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 88 airplanes of U.S. registry. The FAA estimates the following
costs to comply with this proposed AD:
Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
Labor cost Parts cost Cost per product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Up to 2 work-hours x $85 per hour = Up $0 Up to $170................ Up to $14,960.
to $170.
----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any
required actions. The FAA has no way of determining the number of
aircraft that might need this on-condition action:
Estimated Costs of On-Condition Actions
------------------------------------------------------------------------
Cost per
Labor cost Parts cost product
------------------------------------------------------------------------
11 work-hours x $85 per hour = $935... $600 $1,535
------------------------------------------------------------------------
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
