The Pazmany PL-1 Laminar and Pazmany PL-2 are American two-seat trainer and personal light aircraft designed by Ladislao Pazmany to be marketed as a homebuilt aircraft by his company Pazmany Aircraft Corporation. The aircraft was built under license in Taiwan (Republic of China) as the AIDC PL-1B Cheinshou. It was later followed by an improved version the PL-2. The SLAF Aircraft Engineering Wing developed a modified variant of the PL-2 in 1977, which never saw combat but was used in air shows.

Development

The PL-1 Laminar was the first design by Ladislao Pazmany, it was intended to be marketed for the homebuilt market. The prototype first flew on the 23 March 1962. The PL-1 is a cantilever low-wing monoplane with a fixed tricycle landing gear. It has side-by-side seating for a crew of two and is powered by a 95 hp (71 kW) Continental C-90 piston engine. The Aerospace Industrial Development Corporation (AIDC) acquired plans and built a PL-1 for evaluation with a first flight on 26 October 1968. AIDC then built 58 aircraft designated the PL-1B for the Republic of China Air Force and fitted with a 150 hp (112 kW) Avco Lycoming O-320 engine.

Soon after the first flight Pazmany produced an improved design, the PL-2 which had a slight increase in cockpit width and changes to the structure to make it easier for homebuilders. The PL-2 was evaluated by a number of air forces in South East Asia. It was built under license in Indonesia as the LIPNUR LT-200.
