by a fixed skid which stretches from nose the under the wing trailing edge together with a tail bumper protecting the rudder. The SM.31's first flight was made on 11 January 1960. The sole example still exists, though neither airworthy nor on display. Whether it is F-CCHN in the Ailes Ancienne collection in Toulouse or F-CBYK at the Musée Régional de l'Air at Angers is not certain; one is probably the SM.30 and the other the SM.31.
