Design and development
The PA-36 was first announced in 1972 as a new version of the PA-25 Pawnee with a more powerful 285 hp Continental Tiara 6-285 flat-six engine. The aircraft had a new wing with removable leading edges; improved ventilation and heating system; "Safoam" anti-sloshing compound in the fuel tanks; and a larger standard hopper of 30 ft³ (0.85m³). An optional 38 ft³ (1.08 m³) hopper was also available. The type entered service in 1973.
In 1977 a new version became available with a 300 hp (224 kW) Lycoming IO-540-K1G5 engine. The new model was called the PA-36 Pawnee Brave 300 while the original aircraft was redesignated the PA-36 Pawnee Brave 285. In 1978 the Brave 300 became the standard model and another more powerful model was introduced, the PA-36 Brave 375 with a 375 hp (280 kW) Lycoming IO-720-D1CD flat-eight engine.
In 1981 Piper sold the rights in the design to WTA Incorporated, which marketed two versions from 1982 with 375 hp and 400 hp (298 kW) engines as the New Brave 375 and New Brave 400 respectively. It had built a total of 150 New Braves by 1987.
