The SNCASO S.O.7050, S.O.7055, S.O.7056 and S.O.7060 Deauville were single-engine light French civil utility aircraft of the 1940s. Only two airframes were built but were modified with different undercarriages, engines and seating.
Development
[edit]In 1947 SNCASO built two similar light aircraft both carrying the name Deauville. The first, the S.O.7050 which flew on 11 June had a tricycle undercarriage.[1] The second, the S.O.7055 flew on 1 July with a tailwheel undercarriage.[1] The first and possibly the second machine was powered by a 56 kW (75 hp) Mathis 4GO flat-four engine,[1] though the S.O.7055 had a 56 kW (75 hp) Minié 4.DC.32 flat-four at some point.[2] It was later modified into the SO.7056.[1] In 1948 both airframes were re-engined with 78 kW (105 hp) Walter Minor 4-III engines[1] and a third seat was added behind the two front side-by-side seats[citation needed] to produce the S.O.7060 Deauville. The undercarriage of the S.O.7050 was modified to be like that of the SO.7056, so both S.O.7060s had tailwheel gear.[1]
The Deauvilles were of all-metal construction with low/mid set wings of constant chord, straight tapered tail surfaces[3] and a fixed tailwheel undercarriage. The canopy was entirely transparent and slid back to permit the access of pilot and passengers. Dual controls were provided.[4]
Operational history
[edit]The first airframe F-BDVZ was flown by its makers in S.O.7060 form for several years and then by an aero club based at St-Cyr-l'Ecole airfield to the west of Paris during the later 1950s and through the 1960s. The aircraft remained on the French civil aircraft register in May 1967,[5] but was no longer registered in 1973 and it has not survived in preservation.
