**ACTION:**
Proposed rule; correction.
**SUMMARY:**

**SUPPLEMENTARY INFORMATION:**
**Comments Invited**
The FAA invites you to send any written relevant data, views, or arguments about this proposal. Send your comments using a method listed under the *ADDRESSES* section. Include “FAA-2025-5403; Project Identifier AD-2025-01167-T” at the beginning of your comments. The most helpful comments reference a specific portion of the proposal, 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 proposal 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 *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 Raymond Vital, Aviation Safety Engineer, FAA, 2200 South 216th St., Des Moines, WA 98198; phone: 206-231-3521; 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 issued an NPRM (91 FR 931, January 9, 2026) that would apply to certain The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes.
The NPRM proposed to require measuring the freeplay of the horizontal stabilizer pivot hinges and the jackscrew, and applicable on-condition actions. The NPRM was prompted by reports from multiple operators of pitch oscillations events due to excessive horizontal stabilizer freeplay. The FAA is proposing this AD to address excessive horizontal stabilizer freeplay. The unsafe condition, if not addressed, could lead to a flutter event, which can result in loss of control of the airplane.
**Material Incorporated by Reference Under 1 CFR Part 51**
The FAA reviewed Boeing Alert Requirements Bulletin 737-55A1104 RB, dated June 12, 2025. This material specifies procedures for measuring freeplay of the left and right horizontal stabilizer pivot hinges and the jackscrew to determine freeplay value, and applicable on-condition actions. On-condition actions include determining total horizontal stabilizer freeplay, repeating the freeplay measurement procedure of the horizontal stabilizer pivot hinges and the jackscrew, and replacement or repair of any worn parts. 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.
**Need for the Correction**
As published, the docket number referenced throughout the NPRM is incorrect. The NPRM incorrectly references “Docket No. FAA-2025-0540.” The correct docket number is “Docket No. FAA-2025-5403.”
Although no other part of the preamble or regulatory information has been corrected, for clarity the FAA is publishing the entire proposed rule in the *Federal Register* .
The comment due date of the NPRM remains February 23, 2026.
**List of Subjects in 14 CFR Part 39**
Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
