RIN 2120–AA64 Airworthiness Directives; The Boeing Company Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model DC–9–81 (MD–81), DC–9–82 (MD–82), DC–9–83 (MD–83), DC–9–87 (MD–87), and MD– 88 airplanes, and Model DC–9–10, DC– 9–20, DC–9–30, DC–9–40, and DC–9–50 series airplanes. This proposed AD was prompted by the discovery of jammed elevators during takeoff. This proposed AD would require revising the ‘‘Certificate Limitations’’ section of the existing airplane flight manual (AFM) to include a procedure to confirm elevator surfaces are not jammed in the trailing edge down (TED) position. 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 6, 2025.

SUPPLEMENTARY INFORMATION: VerDate Sep<11>2014 16:06 Nov 21, 2024 Jkt 265001 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 PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 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 Katherine Venegas, Aviation Safety Engineer, FAA, 3960 Paramount Boulevard, Lakewood, CA 90712; phone: 562–627–5353; email: katherine.venegas@faa.gov. Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA has received a report indicating that both the left and right elevator were jammed during takeoff resulting in a runway excursion. Elevator surface jamming in the TED direction caused by high-speed wind events can occur while the airplane is parked. This condition may not be detected by feel during preflight control column movement prior to takeoff. The FAA is issuing this AD to address the unsafe condition, which if not addressed, could result in a runway excursion during a rejected takeoff. FAA’s Determination 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 revising the ‘‘Certificate Limitations’’ section of the existing AFM to include a procedure to confirm elevator surfaces are not jammed in the TED position. Compliance With AFM Revisions Section 91.9 (14 CFR 91.9) prohibits any person from operating a civil aircraft without complying with the operating limitations specified in the AFM. FAA regulations also require operators to furnish pilots with any changes to the AFM (14 CFR 121.137) and pilots in command to be familiar with the AFM (14 CFR 91.505). Interim Action The FAA considers that this proposed AD would be an interim action. Boeing is developing a design change to address the unsafe condition. If final action is E:\FR\FM\22NOP1.SGM 22NOP1 Federal Register / Vol. 89, No. 226 / Friday, November 22, 2024 / Proposed Rules later identified, the FAA might consider further rulemaking. Costs of Compliance 92611 airplanes of U.S. registry. The FAA estimates the following costs to comply with this proposed AD: The FAA estimates that this AD, if adopted as proposed, would affect 104 ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators AFM revision ........................... 1 work-hour × $85 per hour = $85 ......................................... $0 $85 $8,840 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 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: (c)(1) through (7) of this AD, certificated in any category.

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 
Katherine Venegas, Aviation Safety Engineer, FAA, 3960 Paramount 
Boulevard, Lakewood, CA 90712; phone: 562-627-5353; 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.

Background

    The FAA has received a report indicating that both the left and 
right elevator were jammed during takeoff resulting in a runway 
excursion. Elevator surface jamming in the TED direction caused by 
high-speed wind events can occur while the airplane is parked. This 
condition may not be detected by feel during preflight control column 
movement prior to takeoff. The FAA is issuing this AD to address the 
unsafe condition, which if not addressed, could result in a runway 
excursion during a rejected takeoff.

FAA's Determination

    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 revising the ``Certificate 
Limitations'' section of the existing AFM to include a procedure to 
confirm elevator surfaces are not jammed in the TED position.

Compliance With AFM Revisions

    Section 91.9 (14 CFR 91.9) prohibits any person from operating a 
civil aircraft without complying with the operating limitations 
specified in the AFM. FAA regulations also require operators to furnish 
pilots with any changes to the AFM (14 CFR 121.137) and pilots in 
command to be familiar with the AFM (14 CFR 91.505).

Interim Action

    The FAA considers that this proposed AD would be an interim action. 
Boeing is developing a design change to address the unsafe condition. 
If final action is

[[Page 92611]]

later identified, the FAA might consider further rulemaking.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 104 airplanes of U.S. registry. The FAA estimates the following 
costs to comply with this proposed AD:

                                     hour = $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 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.
