The Scintex ML 250 Rubis was a French civil utility aircraft of the 1960s.
Design and development
Scintex Aviation had manufactured the two-seat Emeraude from the late 1950s. In 1960 the firm designed the ML 145 four-seat low-wing cabin monoplane, powered by a 145 h.p. Continental O-300-B engine, the single example of which first flew on 25 May 1961.{{Harvnb|Green|1965|p=63}}

Scintex developed the ML 250 with a larger five-seat cabin and fitted with a {{convert|250|hp|kW|0|abbr=on}} Lycoming O-540 engine. This first flew on 3 June 1962.{{Harvnb|Simpson|2001|pp=489–490}} The aircraft was of a graceful design, using an all-wood construction, having a semi-monocoque plywood-covered fuselage and cantilever tapered low wing. The tail fin was swept and the aircraft, unusually, was fitted with a fully retractable tailwheel undercarriage.
Production and service
Eight production examples of the ML 250 Rubis were completed by Scintex during 1964-1965. Whilst the type had an advanced specification, it suffered from competition from contemporary all-metal aircraft types such as the Piper Comanche. The Rubis has remained in service with French private pilots and four were airworthy in 2005.{{Harvnb|Simpson|2001|p=489}} Two of these, including the aircraft pictured right (F-BJMD) were still active on the French civil aircraft register in 2015.{{Harvnb|Partington|2015|p=216}}
