PT-13D / N2S-5 Airplanes Pilot's Flight Operating Instructions

Stearman s Kaydet biplane first flew in 1934, and in 1935 the U.S. Navy acquired the aircraft for use as trainers. Within a year the U.S. Army Air Corps followed suit, buying 26 of the airplanes from Boeing (which had acquired Stearman in 1934). Designated the Model 75 , the Army dubbed the two-seat plane the PT-13 and the Navy the NS. With war looming on the horizon, the need for trainers became pronounced; orders in 1940 topped 3500 airframes. By conflict s end in 1945, over 10,000 were built. The Kaydets were simple, rugged aircraft equipped with a radial engine, fabric-covered wooden wings, and single-leg landing gear. The fuselage, which was also fabric-covered, was built of steel. Most models were equipped with either the Lycoming R-680 (PT-13) or Continental R-670 (PT-17) engine, producing a top speed of 124 mph with a 505-mile range. A 255-hp model received the designation PT-18. The Kaydet continued to fly in the post-WWII era as a trainer and cropduster. Approximately 1,000 Stearmans are still in service in the present day.
