What to do
Operators must inspect the orientation of each affected bolt within 25 flight hours after 21 July 2025, following Leonardo Alert Service Bulletin instructions. If incorrect installation is found, further inspections and corrective actions must be performed before the next flight, including contacting Leonardo for approved repairs if damage or interference is detected. Additionally, maintenance actions using specified outdated Leonardo manuals are prohibited from 21 July 2025 onward.
Summary
EASA Airworthiness Directive 2025-0142R1 is a regulatory document addressing inspection requirements for the cyclic control system's pitch and roll actuator attaching bolts on Leonardo S.p.A. A109 and A119 helicopters, including specific serial numbers of AW119MKII helicopters. The directive mandates inspection of the orientation of these bolts to ensure correct installation and prevent reduced cyclic control range. It applies to bolts attaching pitch and roll actuator assemblies to their respective bellcrank assemblies.
What changed
This revision corrects typographical errors found in the original EASA AD 2025-0142 issued on 7 July 2025. It maintains the original requirements for one-time inspections and corrective actions related to the installation orientation of affected bolts. The revision clarifies maintenance instructions that must no longer be used due to potentially misleading installation guidance.
Why it matters
This directive is critical for aviation professionals because incorrect installation of the affected bolts can reduce the helicopter's cyclic control range, potentially compromising flight safety. Operators and maintenance organizations must ensure compliance to avoid unsafe conditions and maintain airworthiness. The AD also restricts the use of certain maintenance manuals to prevent further installation errors.
