EASA AD 2020-0236-CN
CANCELLED: Equipment / Furnishings — Emergency Escape Slide / Raft Inflation Reservoir — Pressure Check
Summary
EASA Airworthiness Directive Cancellation Notice 2020-0236-CN is a cancellation notice issued by the European Union Aviation Safety Agency for Airbus A318, A319, A320, and A321 aeroplanes. It addresses the emergency escape slide and raft inflation reservoir pressure check requirements previously mandated due to a manufacturing defect in rupture disk assemblies. The cancellation removes the need for repetitive pressure checks on affected parts following updated risk assessments and corrective actions by the manufacturer.
What Changed
This cancellation notice officially cancels EASA AD 2020-0236, which required repetitive pressure checks of emergency escape slide and raft inflation reservoirs on certain Airbus A318, A319, A320, and A321 models. The change follows the manufacturer's issuance of service bulletins for rupture disk replacement during overhaul and the absence of further rupture disk failures. Consequently, the unsafe condition is no longer considered to exist, and no further AD action is required.
Why It Matters
This cancellation is important for aviation professionals because it removes the regulatory burden of repetitive inspections on emergency escape slide inflation reservoirs for affected Airbus aircraft. Operators and maintenance organizations can now rely on the manufacturer's service bulletins for corrective maintenance during overhaul, simplifying compliance and reducing operational disruptions. It also reflects updated safety risk assessments ensuring continued airworthiness without unnecessary inspections.
What To Do
Affected operators and maintenance organizations should discontinue the repetitive pressure checks mandated by the cancelled AD 2020-0236. Instead, they should follow the applicable SAFRAN Aerosystems service bulletins for rupture disk replacement during overhaul as recommended by the FAA and EASA. No new compliance deadlines apply as the cancellation is effective immediately from 16 May 2022.
