What to do
Operators of affected Airbus A318, A319, A320, and A321 aircraft must perform repetitive inspections of main landing gear door actuators within 8 days or 5 flight cycles after the last inspection or before the next flight after August 4, 2025, and continue at specified intervals. Any discrepancies require immediate replacement with serviceable parts. Full replacement of affected actuators must be completed within 12 months for List A parts and 18 months for List B parts from the respective effective dates. Installation of affected parts is prohibited from August 4, 2025, onward.
Summary
EASA Airworthiness Directive 2025-0158R2 is an updated regulatory requirement addressing inspections and corrective actions for main landing gear door actuators on Airbus A318, A319, A320, and A321 aircraft models. It targets actuators with specific part number 114122015 and serial numbers listed in Airbus Alert Operators Transmission A32N033-24, aiming to prevent landing gear extension issues caused by actuator assembly errors. The directive mandates repetitive inspections and eventual replacement or modification of affected parts to ensure continued airworthiness.
What changed
This revision of EASA AD 2025-0158 introduces reference to X-ray inspection instructions as an acceptable method to terminate repetitive inspections of affected actuators. It also updates the list of affected serial numbers and includes the newly certified Airbus A321-271NY model in the applicability. The directive retains previous inspection and replacement requirements while incorporating new compliance options.
Why it matters
This directive is critical for operators and maintenance organizations to prevent landing gear extension failures that could cause aircraft damage or unsafe conditions. Compliance ensures that affected actuators are inspected and corrected promptly, reducing the risk of in-service malfunctions. It also provides clear guidance on acceptable inspection methods and timelines, aiding regulatory compliance and maintenance planning.
