EASA SIB 2018-15: Use of Water Surfaces as Helicopter Safe Forced Landing Areas

What to do

Helicopter operators should incorporate the use of water surfaces as forced landing areas into their safety risk management processes. They are advised to consider flight paths with safer ground landing options when possible, provide additional pilot training on overwater flight challenges and emergency water landings, review passenger briefing procedures for water evacuations, and ensure helicopters are properly equipped with emergency flotation devices. No specific compliance deadlines are stated.

Summary

EASA Safety Information Bulletin No. 2018-15 is an informational document addressing the use of water surfaces as safe forced landing areas for helicopters, specifically single-engine helicopters and twin-engine helicopters unable to maintain level flight after power loss. It highlights the risks and challenges associated with emergency water landings, including visual illusions like flat light and difficulties in underwater egress. The bulletin references relevant EU regulations and FAA guidance to provide context for helicopter operations over water.

What changed

This new Safety Information Bulletin introduces guidance and recommendations for helicopter operators regarding the risks of using water surfaces as forced landing areas. It emphasizes the need for hazard identification and risk management related to overwater flights and emergency water landings, without imposing mandatory regulatory changes or operational directives.

Why it matters

The bulletin matters because it raises awareness among helicopter operators and pilots about the underestimated risks of emergency water landings, which can impact flight safety and emergency preparedness. Understanding these risks helps operators improve pilot training, operational procedures, and equipment choices, thereby enhancing safety during overwater flights and emergency situations.
