What to do
Operators of affected Airbus A330 and A340 aeroplanes must determine within three months of 12 November 2025 whether any affected AOA backplate tasks have been performed, following Airbus Alert Operators Transmission A34L009-24R1. If affected tasks are found, corrective actions including temporary operational procedures and contacting Airbus for repair instructions must be completed within specified timeframes. Additionally, no further affected tasks, modifications, or repairs may be performed from the effective date onward.
Summary
EASA Airworthiness Directive 2025-0241 is an airworthiness directive affecting Airbus A330 and A340 aeroplanes, specifically those with Angle of Attack (AOA) backplates having Part Number A5341054920000. The directive addresses potential safety issues related to incorrect data in Airbus technical drawings used for reinstalling AOA backplates. It mandates inspections and corrective actions to ensure the accuracy and reliability of AOA sensor data on affected aircraft.
What changed
This new regulation introduces requirements to determine if affected maintenance tasks, modifications, or repairs involving specific Airbus AOA backplate drawings have been performed. Depending on findings, operators must implement corrective actions including contacting Airbus for approved repair instructions and applying temporary operational limitations. It also prohibits further affected tasks on any aeroplane from the effective date.
Why it matters
This directive is critical for aviation professionals because erroneous AOA sensor data can lead to reduced aircraft control, posing a safety risk. Operators and maintenance organizations must ensure compliance to maintain aircraft airworthiness and avoid operational disruptions. Compliance teams need to track affected aircraft and implement required inspections and repairs within specified deadlines to meet regulatory obligations.
