The Pazmany PL-4A is a single-seat, single-engine sport aircraft developed in the United States and first flown in 1972. It is marketed for homebuilding from plans, and 686 sets had sold by 1985. The PL-4A is a conventional, low-wing cantilever monoplane with an enclosed cabin and fixed, tailwheel undercarriage. The design features a T-tail, chosen to facilitate folding the wings. Construction throughout is of metal, using standard extruded sections for the longerons and pop rivets as the basic fastener. The standard powerplant is a Volkswagen air-cooled engine of 60 hp (45 kW) Construction time is estimated to be around 1,000–1,500 hours.
