Removing Airworthiness Directive 2025-23-52, Amendment 39-23195 (90 FR 52555, November 21, 2025); and b. Adding the following new airworthiness directive: 2026-01-08 Airbus Helicopters: Amendment 39-23236; Docket No. FAA-2026-0011; Project Identifier MCAI-2025-01758-R. (a) Effective Date This airworthiness directive (AD) is effective February 2, 2026.

(d) Subject Joint Aircraft System Component (JASC) Code 6510, Tail Rotor Drive. (e) Unsafe Condition This AD was prompted by a determination that the service life limit of the center shaft assembly needs to be corrected because a crack could initiate on the center shaft assembly. The FAA is issuing this AD to address cracking on a center shaft assembly. The unsafe condition, if not addressed, could result in structural failure of the tail rotor drive shaft with consequent loss of control of a helicopter. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Required Actions Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) Emergency AD 2025-0262-E, dated November 25, 2025 (EASA Emergency AD 2025-0262-E).

(i) No Reporting and Return of Parts Requirements Although the material referenced in EASA Emergency AD 2025-0262-E specifies to submit certain information to the manufacturer and to return the parts to the manufacturer, this AD does not require those actions.
