EASA AD G-2021-0003: SURVITEC GROUP LIMITED - Halo Passenger Life Jacket - Inspection

What to do

Operators must perform a one-time inspection of the affected EBS burst plugs within one month of the effective date, following Survitec Alert Service Bulletin 25-206-A. If discrepancies are found, the EBS cylinder must be purged and replaced with a serviceable part. No affected EBS parts may be installed unless the service bulletin has been accomplished to the latest approved revision.

Summary

The Civil Aviation Authority Airworthiness Directive G-2021-0003 addresses the inspection of the Survitec Group Limited Halo Passenger Lifejacket Emergency Breathing System (EBS) part number 12677009 fitted to lifejacket part numbers 00031010 and 00031031. This directive mandates a one-time inspection to verify the correct burst plug installation to ensure the EBS functions properly during ditching emergencies. It applies specifically to the Survitec Halo passenger lifejackets equipped with the affected EBS units.

What changed

This new Airworthiness Directive introduces a mandatory inspection requirement for the burst plug on the affected EBS units after an incident revealed incorrect burst plugs were installed. It requires operators to inspect and, if necessary, replace the burst plug with the correct 4500 PSI / 310 BAR version as per Survitec Alert Service Bulletin 25-206-A. Additionally, it prohibits installation of affected parts unless the service bulletin has been complied with.

Why it matters

This directive is critical for aviation safety as an incorrect burst plug can cause failure of the Emergency Breathing System during ditching, increasing the risk of drowning. Operators, maintenance organizations, and compliance teams must ensure the EBS units are inspected and corrected promptly to maintain airworthiness and passenger safety. Compliance with this AD prevents potential life-threatening malfunctions of life-saving equipment.
