Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

[[Page 102020]]

SUMMARY: 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.

DATES: The FAA must receive comments on this proposed AD by January 31, 
2025.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

    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 
regulations.gov, including any personal information you provide. The 
agency will also post a report summarizing each substantive verbal 
contact received about this NPRM.

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 NPRM 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 NPRM, 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 NPRM. Submissions containing CBI should be sent to Joe 
Salameh, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410, 
Westbury, NY 11590; telephone: 206-231-3536; email: 
[email protected]. Any commentary that the FAA receives which is not 
specifically designated as CBI will be placed in the public docket for 
this rulemaking.

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 regulations.gov 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.
