The Ca.146 was a derivative of the Ca.127, and was similar in being a high-wing monoplane. However, the Ca.146 was of all-wood construction and had no armament provisions. The Ca.146 prototype (registration MM.131) flew in 1935 and showed good flight characteristics, but won no orders from the Regia Aeronautica.
