What to do
Operators must replace affected BSCUs that trigger fault signatures before the next flight and update their MMEL and Minimum Equipment List (MEL) accordingly. For aircraft without affected parts installed, installation of such parts is prohibited. Compliance with these actions is required from 10 March 2022, with ongoing adherence to updated operational and maintenance instructions.
Summary
EASA Airworthiness Directive 2022-0032R1 is an amendment addressing the braking and steering control units (BSCU) on Airbus A318, A319, A320, and A321 aeroplanes. It focuses on BSCUs with Part Number E21327307, which have shown failures leading to loss of anti-skid function, alternate braking mode, and nose wheel steering. The directive updates operational procedures and maintenance requirements to mitigate these risks.
What changed
This revision updates the group definitions of affected aeroplanes and modifies installation rules to allow installation of affected BSCUs on certain groups, provided they are serviceable and the Master Minimum Equipment List (MMEL) is updated. It also incorporates revised Flight Operations Transmission (FOT) and MMEL updates, relaxing previous prohibitions on installing affected parts on some aircraft.
Why it matters
The directive is critical for operators and maintenance organizations to prevent potential loss of braking performance and increased stopping distances, which could lead to runway excursions. Compliance ensures continued airworthiness and operational safety by addressing known BSCU failures. It also clarifies installation and operational requirements, helping compliance teams manage fleet configurations effectively.
