 The type proved an immediate success in service, and orders for another four machines plus five single-seat derivatives (designated the Type 502 by Avro) soon followed.Other examples produced included six for the British Admiralty's Air Department, one presented to the government of Portugal (paid for by public subscription), one kept by Avro as a company demonstrator, and one bought by a private individual, J. Laurence Hall, which was commandeered by the War Office at the outbreak of World War I).The first prototype was destroyed in a crash on 29 June 1913 that killed its student pilot.
