Development

Roche Aviation designed the T.35 during the latter part of World War II as a low-wing touring monoplane with fixed undercarriage. The first example made its maiden flight in September 1944.^[1] After the war's end, Roche built a series of basically similar sub-models with varying powerplants and seating arrangements. The T.35 models were two-seat aircraft and the T.39 models accommodated three or four persons.^[2] Production was terminated after 15 examples of the series had been completed.

Operational history

The T.35 and T.39 series was flown by private pilot owners and by members of French light aero clubs until at least the mid 1960s. Three examples remained on the French civil aircraft register in January 1964.^[3] No examples are currently preserved in collections or museums.^[4]
