The Aeronautica Lombarda AL-12P, sometimes referred to as the Ambrosini AL-12P, was an Italian military transport glider constructed by Aeronautica Lombarda during the Second World War for use by the Italian Army.
Design and development

Conceived by A. Ambrosini, the AL-12P featured a high-wing cantilever monoplane configuration with a fuselage framed by wood ribs and sheathed in stressed molded plywood.[1] Its wings incorporated a spar made from layered spruce plywood and were covered with plywood panels, except for the ailerons which were fabric-covered.[1] The aircraft was equipped with sizable slotted spoilers that extended both above and below the wing surface at right angles.[1] The cockpit housed the pilot and co-pilot seated side by side within a nose section constructed from welded steel tubes covered in plywood; this nose was hinged to facilitate loading cargo into the fuselage. Additionally, a passenger door was installed on the right side of the fuselage.[1] The glider was capable of transporting twelve fully equipped soldiers or an equivalent load of equipment.[1] In total, sixteen AL-12Ps were produced by the manufacturer for deployment with the Italian Army.[1]

Following the conclusion of World War II, S.A.I.-Ambrosini converted at least one AL-12P by fitting it with two 225 horsepower (168 kW) Alfa Romeo 115ter six-cylinder air-cooled engines. This modification included an updated landing gear design featuring shock absorber struts mounted on the engine nacelles, supported by V-struts connected to the sides of the fuselage.[2]
