AI-generated summary of the official EASA document. Verify against the PDF before acting.
What to do
Operators of affected Airbus A321NX models must inspect and modify affected escape slide inflation reservoirs and orifice fittings according to the specified Airbus and Safran service bulletins. Group 1 aeroplanes must complete modifications within 36 months of 28 July 2025. Installation of affected parts is restricted unless properly modified or replaced. Compliance with all inspection and corrective actions must be documented and completed within the stated deadlines.
Summary
EASA Airworthiness Directive 2025-0151R2 is an updated regulatory document addressing safety concerns related to the escape slide inflation reservoir regulator valve on Airbus A321-251NX, A321-252NX, A321-253NX, A321-271NX, and A321-272NX aeroplanes. It mandates inspection, modification, and replacement of affected reservoirs and orifice fittings to prevent uncommanded deployment of escape slides during flight. The directive applies to all manufacturer serial numbers of the specified aircraft models.
What changed
EASA AD 2025-0151R2 revises the previous AD 2025-0151R1 to clarify installation requirements and correct potential misinterpretations regarding affected parts listed in vendor service bulletins. It retains prior inspection and modification requirements while introducing updated compliance instructions and extending deadlines for modification of affected reservoirs. The revision also incorporates feedback received during consultation to improve clarity and compliance.
Why it matters
This directive is critical for aviation professionals as it addresses a safety risk of uncommanded escape slide deployment in flight, which could lead to reduced aircraft control and potential damage. Operators and maintenance organizations must ensure compliance to maintain airworthiness and avoid operational disruptions. Clear guidance on inspection, modification, and parts installation helps streamline maintenance planning and regulatory adherence.
