Definition
An operation in which a person provides flight training to another person in exchange for compensation, whether paid in money, goods, or services. Under FAR Part 91, an aircraft used to give flight instruction for hire (when the instructor provides the aircraft) is one of the categories that requires a 100-hour inspection in addition to the annual inspection.
Plain English
Teaching someone to fly when you are getting paid for it. If the instructor also supplies the airplane, the rules require that airplane to be inspected more often.
Context Anchor
Seen when deciding whether an aircraft used for training must have a current 100-hour inspection.
Derivation
Hire comes from an old English word meaning to pay someone for work or service. That helps here because for hire is about being paid for the instruction, not just about an aircraft being rented.
Why Pilots Care
Determines whether a training aircraft must receive a 100-hour inspection in addition to its annual inspection.
Intuition Check
Do not assume flight instruction for hire means every lesson in any aircraft. In this inspection rule, the key idea is paid instruction using an aircraft provided for that instruction.
Example Sentence 1
Because the flight school provides the aircraft and charges students for lessons, each training airplane is used for flight instruction for hire and must have a 100-hour inspection.
Example Sentence 2
A private pilot giving an unpaid introductory flight does not qualify as flight instruction for hire.
