AVweb The Aircraft Owners and Pilots Association (AOPA), Experimental Aircraft Association (EAA) and General Aviation Manufacturers Association (GAMA) have sent a joint letter to the FAA calling on the agency to clarify how a recent federal court ruling will affect compensated flight training. The ruling denied a petition to review an emergency cease-and-desist order issued by the FAA against Florida-based “vintage” flight school Warbird Adventures. The order stipulated that Warbird must stop providing paid flight instruction in its Curtiss P-40N because the aircraft “was not certified for that purpose.” In denying the petition and upholding the cease-and-desist order, the court emphasized that 14 CFR §91.315 prohibits the use of limited category aircraft such as the P-40N for carrying people or property for compensation or hire. The judgment (PDF) further stated that using the aircraft for paid flight training qualified as flight for compensation since, in the court’s opinion, “When a student is learning to fly in an airplane, the student is “carr[ied] … And when the student is paying for the instruction, the student is being carried ‘for compensation.’”
