Description

The FAA is issuing a correction to a previously published airworthiness directive (AD) that applies to certain International Aero Engines AG models. The correction addresses a typographical error in paragraph (g) of the regulatory text, specifically the omission of the word "blade." The AD requires replacement of affected 3rd stage high-pressure compressor rotor blades to prevent engine failures that could lead to fires or in-flight shutdowns. The correction does not change the original intent or compliance requirements of the AD, which remains effective from September 24, 2026.
