MS.250
Role trainer
Manufacturer Morane-Saulnier
First flight 1929
Number built 2

The Morane-Saulnier MS.250 was a crew-trainer aircraft built by Morane-Saulnier in the late 1920s.

Design[edit]

The MS.250 was a parasol-wing monoplane with swept-back wings, similar to the Morane-Saulnier MS.230, but differed in having a new tail. The cockpits had windscreens, and the rear cockpit had a gun ring. The pilot-instructor manned the front cockpit, and the trainee observer manned the rear cockpit.[1] A second aircraft was built with a more powerful engine as the MS.251.[2]

Variants[edit]

MS.250
Initial design prototype, powered by a 230 hp (170 kW) Salmson 9Ab radial engine; one built.[1]
MS.251
A second aircraft, powered by a 240 hp (180 kW) Lorraine 7Mc radial engine.[2]
