On 23 June 1921, a Blériot-SPAD S.27, F-CMAY of CMA was en route from Croydon to Le Bourget. It encountered technical problems and attempted a forced landing, possibly aiming for Bekesbourne Aerodrome, Kent, but crashed onto an adjacent railway line, first hitting telegraph cables which would have softened the impact. The two passengers were unharmed, while the pilot received minor injuries having been pinned underneath the aircraft. The aircraft was written off.[3]
On 3 June 1922, CMA's Blériot-SPAD S.33 F-ACMH en route from Croydon to Le Bourget crashed into the English Channel off Folkestone, killing both passengers and the pilot.[4]
On 15 March 1923, Farman F.60 Goliath F-AEIE overran the runway on landing at Croydon and collided with a building. The aircraft was later repaired and returned to service.[5]
On 3 December 1923, Goliath F-AEIF, which may have been operated by CMA, crashed at Littlestone, Kent.[5]
