What changed
EASA Airworthiness Directive 2025-0023-E supersedes AD 2023-0079-E and expands the applicability to include additional serial numbers, specifically Group 1 aeroplanes previously not covered.

Why it matters
This directive is critical for maintaining safe flight control operation by preventing potential loosening of the flaperon bellcrank bolt, which could lead to reduced aircraft control.
