The Morane-Saulnier MS-700 Pétrel (English: Petrel) was a French four-seat cabin-monoplane designed and built by Morane-Saulnier, only three prototypes were built.[1]

Design and development[edit]

The MS-700 was a twin-engined, low-wing, cabin-monoplane with a retractable tricycle landing gear and powered by two 160 hp (119 kW) Potez 4D-33 four-cylinder, inverted inline piston engines.[1] The prototype, with French test registration F-WFDC, first flew on the 8 January 1949.[1] The aircraft was intended as a light liaison aircraft and the second prototype made a demonstration tour of Africa at the end of 1950.[1] In 1952 the second prototype was re-engined with two Mathis G8-20 engines and re-designated MS-701.[1] On 3 January 1951 a third prototype first flew, it was a MS-703 with a longer fuselage for six-seats and two 179 kW (240 hp) Salmson 8.AS.OO engines.[1] After being used by the company for a number of years the first prototype was due to be modified in the late 1950s to the same standards as the MS-703 but with 220 hp (164 kW) Potez engines but it was not converted and instead was withdrawn from use.[1] Only the three prototypes were built and the type did not enter production.[1]
