The Beneš-Mráz Bibi was a 1930s Czechoslovak two-seat touring aircraft.
Design and development The Bibi was designed and manufactured by Beneš-Mráz, developed from the Beta-Minor design. The Bibi was a lighter, smaller aircraft in which the seats were side-by-side instead of in tandem, and the cockpits were fully enclosed, retaining the Beta-Minor's cantilever low-wing cantilever monoplane layout, with fixed tailwheel undercarriage. Development of the Bibi began with the Be-501 two-seat cabin tourer, and culminated with the Be-555 Super Bibi.Jackson 1974, p. 358
Operational history One example of the Be-550 Bibi (OK-BET) was imported into the United Kingdom, stored during World War II, then registered as G-AGSR until a fatal crash in 1951.
