EASA AD 2025-0161
Doors — Jettisonable Window System Retaining Rings — Inspection
Summary
EASA Airworthiness Directive 2025-0161 is an airworthiness directive addressing Airbus Helicopters H160-B models delivered before 01 May 2025. It mandates inspection of the jettisonable window system retaining rings to ensure proper installation on hinge pins. This directive aims to maintain safe evacuation capabilities by preventing missing retaining rings that could hinder window jettisoning during emergencies.
What Changed
This new airworthiness directive introduces a one-time inspection requirement for the retaining rings on jettisonable window systems of Airbus Helicopters H160-B helicopters. It requires corrective action if any retaining rings are found missing, specifying immediate or six-month compliance depending on the location of the missing ring. The directive is based on findings that some retaining rings were not installed during production.
Why It Matters
This directive is critical for aviation professionals as missing retaining rings could prevent emergency evacuation by obstructing window jettisoning. Operators and maintenance teams must ensure compliance to avoid safety risks and regulatory violations. Timely inspections and corrective actions help maintain the continuing airworthiness and operational safety of affected helicopters.
What To Do
Operators of Airbus Helicopters H160-B delivered before 01 May 2025 must inspect all affected jettisonable window system retaining rings within six months of 12 August 2025. If missing rings are found in specified critical positions, they must be installed before the next flight. For other positions, installation must occur within six months after inspection, following the instructions in Airbus Helicopters Alert Service Bulletin 160-52-20-0002.
