ACTION: Final rule. SUMMARY: The FAA is adopting 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 AD was prompted by the discovery of jammed elevators during takeoff. This AD requires 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 issuing this AD to address the unsafe condition on these products. DATES: This AD is effective June 12, 2025. ADDRESSES: AD Docket: You may examine the AD docket at regulations.gov under Docket No. FAA-2024-2427; or in person at Docket Operations between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this final rule, any comments received, and other information.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to 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. The NPRM published in the Federal Register on November 22, 2024 (89 FR 92610). The NPRM was prompted by the discovery of jammed elevators during takeoff. In the NPRM, the FAA proposed to 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. The FAA is issuing this AD to address jammed elevators, which if not addressed, could result in the inability of the airplane to rotate at rotation speed VR, and lead to a rejected takeoff and high-speed runway excursion. Discussion of Final Airworthiness Directive Comments The FAA received comments from The Boeing Company and an individual commenter. The following presents the comments received on the NPRM and the FAA's response to each comment. Request for Revision of Un…
