We got a charter request for an elderly lady who is reportedly in a wheelchair and needs assistance - ie dead weight, on and off the plane (BE-200). Her husband is travelling with to help (how old I don't know). My first reaction was to suggest an air ambulance (I used to fly). They said they did not need an air ambulance service. (Money?). My concern of course is for emergency evacuation and possible injury if we try to assist normal boarding and off-loading with no real equipment on-hand. I don't know if she will end up needing a backboard or what to get on and off. What is the liability exposure here? Any regulatory reference that addresses this as far as emergency evac.? My company is concerned that if we refuse that might discrimantory (sp?). As a non-sched. Part 135 can we refuse anybody on any grounds or is AARP, ACLU, etc going to have problems with this?
