Boisavia B-60 Mercurey




In 1946, Lucien Tieles built the prototype of a three-seat high wing monoplane - the B.50 Muscadet. This aircraft, powered by an 100 hp Renault engine, was then redesigned with a higher rear fuselage decking to provide full four-seat capacity. Fitted with a 140 hp Renault 4 Pei engine, and designated B.60 Mercurey, the first aircraft made its maiden flight on 3 April, 1949 and Tieles established the Société Boisavia to build the aircraft commercially. It was a conventional high-wing braced monoplane with fixed tailwheel undercarriage. Forty six were built and found use in the normal general aviation roles of tourer, trainer, agricultural aircraft, and glider tug.

While the prototype Mercurey had used a Renault engine, most production units were the B.601L with an 190 hp Lycoming flat four engine. With the same airframe the company was able to produce small numbers of other versions with different engines and Mercurey production continued until the middle of 1962 with virtually all sales being made in France or its overseas territories. Serial numbers ran from c/n 1 to 5, 18 to 29, 51 to 55 and 100 to 116. In addition, the various prototypes had unique serial numbers.
