EASA AD 2025-0009
Doors — Jettisonable Window Mechanism — Lubrication / Operational Test
Summary
EASA Airworthiness Directive 2025-0009 is an airworthiness directive applicable to Airbus Helicopters H160-B models. It addresses issues with the jettisonable window mechanism, specifically requiring lubrication and operational testing of the locking fingers to ensure proper function. This directive aims to maintain safe evacuation capabilities by preventing difficulties in window jettisoning during emergencies.
What Changed
This new directive introduces mandatory repetitive lubrication and operational testing of the affected jettisonable window locking mechanisms on H160-B helicopters. It requires these actions within 110 flight hours or 3 months after the effective date and then every 6 months thereafter. Additionally, it mandates lubrication and testing before installation of any affected parts.
Why It Matters
This directive is critical for aviation professionals because it addresses a safety risk that could hinder emergency evacuation by preventing window jettisoning. Operators and maintenance teams must comply to ensure continued airworthiness and regulatory compliance. Failure to perform the required maintenance could compromise occupant safety during emergencies.
What To Do
Operators of Airbus Helicopters H160-B must lubricate the affected jettisonable window locking parts within 110 flight hours or 3 months after 24 January 2025, and repeat this every 6 months. After each lubrication, an operational test must be performed, and any issues must be reported to Airbus Helicopters for corrective action. Before installing any affected parts, they must be lubricated and tested according to the specified service bulletin.
