So, from what I can gather by this 'recommendation' from Robinson that crew and passengers don helmets and Nomex before flying in the R-44, if they don't follow this 'recommendation, then Robinson wouldn't technically be liable should they be burned or their head injured in a fire or crash.
I'd love to hear the answers given to paying customers on why they need to don Nomex and helmets.
Anyone aware of any operator providing such safety gear to their customers?
