What to do
Operators must replace all affected nylon bushes with specified bronze bushes within 72 months from 7 October 2025, following the instructions in Airbus Service Bulletins A320-53-1542 and A320-53-1543. After replacement, affected nylon bushes must not be reinstalled in the specified seat rail areas. For any instructions requiring contact with Airbus, operators must obtain and comply with additional guidance within the prescribed compliance times.
Summary
EASA Airworthiness Directive 2025-0207R1 is an updated regulatory requirement addressing the replacement of nylon bushes with bronze bushes in the seat rail connections of Airbus A318, A319, A320, and A321 aircraft. This directive applies to all manufacturer serial numbers except those with Airbus modifications 152721 and 154725 incorporated. It aims to ensure continued airworthiness by mitigating risks associated with broken bolts in critical seat rail areas.
What changed
This revision of EASA AD 2025-0207 updates Appendix 1 to clarify which part numbers of nylon bushes are considered affected and which are not. It refines the list of parts requiring replacement and confirms the prohibition of reinstalling affected nylon bushes after modification. The directive maintains the original replacement requirements but provides clearer guidance on part applicability.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk that could lead to seat detachment and passenger injuries during emergency landings. Operators and maintenance organizations must comply to ensure aircraft structural integrity and passenger safety. Clear identification of affected parts helps streamline maintenance planning and compliance verification.
