The Boisavia B.260 Anjou (later developed by SIPA as the Sipavia Anjou) was a four-seat twin-engine light aircraft developed in France in the 1950s. It was a low-wing cantilever monoplane of conventional configuration with retractable tricycle undercarriage. Intended by Boisavia as a touring aircraft, it did not find a market and only the single prototype was constructed. At this point, the firm sold the design to SIPA, which modified the design and re-engined it with Lycoming O-360 engines, but found that they could not sell it either. At a time when the twin-engine light plane market was already dominated by all-metal American aircraft, the Anjou's fabric-over-tube construction was something of an anachronism, and all development was soon ceased. Plans to develop a stretched version with three extra seats and Potez 4D engines were also abandoned.
