Press Before renting a plane from a private person, what should we discuss and what should I check? Of course, I would want to verify the airworthiness of the plane. What sort of things do we need to agree upon? What sort of insurance is necessary? Does renting a plane from someone (exchange of $ for airplane time) trigger the requirement for a 100-hour inspection (operation for hire)?
