MACCHI M.14 Italy

   Owing little to the Hanriot HD.I that was licence-built by Nieuport-Macchi, the M.14 single-seat sesquiplane fighter was designed by Alessandro Tonini. Of wooden construction and featuring Warren truss style interplane bracing, the M.14 was powered by a 110 hp Le Rhone 9J nine-cylinder rotary engine and had provision for an armament of twin synchronised 7,7-mm Vickers guns. Flight testing commenced in the spring of 1918, but the prototype was destroyed in June of that year. Nevertheless, a series of 10 M.14 fighters was built, official evaluation trials being conducted at Montecelio during 1919. However, no additional orders were placed for the type and those M.14s completed were employed as advanced trainers, at least one receiving a civil registration (I-BADG).

Macchi M.14

  The M.14 single-seat sesquiplane fighter was designed by Alessandro Tonini. While certainly not a direct copy of the Hanriot HD.1s that Macchi had produced under license, it did bear an uncanny likeness of that machine. It was of all wood construction and had a Warren truss type interplane bracing. The engine was a 110-hp Le Rhone 9J nine-cylinder rotary. The armament was two synchronized 7,7-mm Vickers guns.

Technical

  Wings - two spar wooden wing covered in fabric. Ailerons on the upper wing only. The wings had a marked dihedral on the upper wing, while the lower wings were straight. The “W” shaped struts (joined at the mid portion of the lower wing on each side, was later seen in other Italian fighter designs, most notably the CR.42.
  Fuselage - similar to the HD.1. The fuselage sides were flat.
  Power Plant - The engine was a 110-hp Le Rhone 9J rotary engine for the M.14 bis fighter and a 80-hp engine or the M.14 fighter trainer. The 90-hp version may have never been built.
  Landing Gear - Landing gear with faired struts an additional fairing covering the landing gear strut. These struts were intended to act as an auxiliary airfoil.

Testing

  Flight testing commenced in the spring of 1918, but the prototype was destroyed in June of that year when it crashed, killing Clemente Maggiora. Aircraft 20931 underwent evaluation in 1919 at Montecelio. By December 1919 there were seven M.14s at Montecelio. However, no additional orders were forthcoming. The M.14’s performance was considered satisfactory, but not notably superior to the other Italian fighters then in service. The ten M.14s were employed as advanced trainers; these carried serials 20931 to 20940. At least one (20935) appeared on the civil register carrying serial I-BADG.

Foreign Service

  Spain - An example was purchased in Spain. According to the then Lieutenant Gomez Spencer, who flew the sole prototype at Getafe around 1922, it cost the Aeronautica Militar only 6,000 pesetas. It was equipped with a 110-hp Le Rhone 9J engine. No further details are known.
