Development

The PM XI was designed by Peyret-Mauboussin as a Salmson-engined two-seat touring and sporting aircraft of wooden construction, an enlarged and more powerful development of the single-seat Peyret-Mauboussin PM X.[1] Two examples were built.[2]

Operational history

Two PM.XIs were built in parallel.[2] The airframe c/n 02 was finished first and first flew on 9 July 1930. It was registered as F-AJUL. c/n 01 F-AKFD was ordered by the French Service Technique.[3]

In July F-AJUL took part in the Challenge International de Tourisme 1930 touring aircraft contest, piloted by Charles Fauvel,[4] but damaged a landing gear in a compulsory landing.[5] By November one was flying at their Orly base and the other was under test for its CoA at Villacoublay.[2] F-AJUL was later flown by Rene Lefevre from Paris to Tananarive, Madagascar, between 1 and 14 December 1931. The total distance flown was 11,000 km at an average speed of 120 km/hour. He also flew it, after fitting extra tankage in the cabin, from Paris to Saigon in 10 days during December 1932, a distance of 10,500 km (6,500 mi). The return trip in February 1933 took 8 days.[3]

This aircraft is stored without wings at the Musee Castel-Mauboussin at Cuers-Pierrefeu airfield near Toulon in southern France, and can be viewed by prior permission.[6]
