AGENCY:
Federal Aviation Administration (FAA), DOT.
ACTION:
Final rule.
SUMMARY:
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-9 and 787-10 airplanes. This AD was prompted by reports of multiple supplier notices of escapement (NOEs) indicating that ram air turbine (RAT) forward fittings were possibly manufactured with an incorrect titanium alloy material. This AD requires a high frequency eddy current (HFEC) or handheld X-ray fluorescence (XRF) spectrometer inspection of the RAT forward fitting to determine the titanium alloy material and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
DATES:
This AD is effective February 20, 2026.
The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of February 20, 2026.

Background
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 787-9 and 787-10 airplanes. The NPRM was published in the
