EASA SIB 2018-16: Use of Restraint Systems in Helicopter Operations

What to do

Operators using restraint systems other than seat belts should review their equipment, operating procedures, training programs, and risk assessments to confirm compliance with Air OPS Regulation requirements. They must ensure that restraint systems have easily accessible quick-release mechanisms to facilitate rapid egress in emergencies. No mandatory compliance deadlines are specified, but prompt action is recommended to enhance safety.

Summary

EASA Safety Information Bulletin 2018-16 is a guidance document addressing the use of restraint systems in helicopter operations, specifically focusing on systems other than standard seat belts. It references a fatal accident involving an Airbus Helicopters AS 350 B2 near New York City and highlights regulatory requirements under Commission Regulation (EU) No 965/2012 for various operator categories. The bulletin emphasizes the importance of quick-release restraint systems to ensure passenger safety during emergency egress.

What changed

This bulletin introduces recommendations following the FAA's Emergency Order of Prohibition FAA-2018-0243, which restricts the use of supplemental passenger restraint systems that cannot be quickly released during doors-off helicopter flights. It clarifies that restraint systems without quick-release mechanisms may adversely affect aircraft airworthiness and reinforces compliance with existing Air OPS Regulation requirements regarding restraint systems and passenger briefing.

Why it matters

This information is critical for helicopter operators, maintenance organizations, and compliance teams to ensure passenger safety and regulatory compliance. Improper restraint systems can hinder emergency evacuation, increasing risk during accidents such as water impacts or post-crash fires. Adhering to these guidelines helps prevent similar accidents and aligns operational practices with both EASA and FAA safety expectations.
