The Piper PA-36 Brave is an agricultural aircraft produced by the US aircraft manufacturer Piper Aircraft Corporation .
History and construction
The aircraft is a single-seat, single-engine, low-wing aircraft with a rigid rear wheel landing gear. Its design is based on the Piper PA-25 , but it is improved in many details and more powerful. The fuselage of the PA-36 consists of a chrome-molybdenum tubular frame to which the fairings are attached. A roll bar is also part of the construction. The wings have two spars and are made of aluminum except for the leading edges and wing tips made of fiberglass-reinforced plastic . The spray tank in front of the cockpit holds either 850 l or 1075 l. The spray device can deliver 863 l per minute. The cockpit is hermetically sealed from the fuselage and is supplied with fresh air through a hood on the roof. The fuel tanks are filled with polyurethane, which functions as a fire inhibitor in the event of an accident as well as a surge reducer.
The prototype was named PA-36-260 Pawnee II and made its maiden flight on November 17, 1969. It was equipped with a 195 kW Lycoming O-540E . It was replaced by the Continental 6-285 engine with 210 kW intended for series production , with which the second prototype was also equipped.
The PA-36 was approved by the FAA on October 9, 1972 ; Production of the PA-36-285 Pawnee Brave began in 1973. The Continental engine proved to be too unreliable for the rough agricultural operation. A Lycoming IO-540 with 225 kW was therefore used from 1977. These machines were given the designation PA-36-300, then from 1978 the PA-36 Brave 300. From 1978 the more powerful Lycoming IO-720 with initially 280 kW was also available. The machine was externally recognizable by the modified engine cowling and a three-blade instead of the two-blade propeller and was called PA-36 Brave 375. From 1982 a more powerful version of the IO-720 was used, which was named PA-36 Brave 400 with 300 kW output.
In 1981 the rights to the construction were sold to WTA Incorporated , which marketed the two versions PA-36 New Brave 375 and PA-36 New Brave 400 . WTA built 150 of both versions until 1987.
