Hispano-Suiza 9 & 14 Aircraft Engine Manuals Collection

This collection brings together the essential technical documentation for the Hispano-Suiza 9V and 14-series radial engines — the French-built, Wright-licensed powerplants that equipped the Armée de l'Air during the critical years of 1939–1940. Sourced from original French-language factory publications, these manuals provide an authoritative reference for historians, restorers, and aviation researchers working with pre-war French aviation technology.

Definitive Collection with Free Lifetime Updates: This is a living collection that we continuously expand and refine. As we acquire additional Hispano-Suiza 9 & 14 documentation, technical bulletins, or variant-specific materials, we update this collection and provide free lifetime updates to all purchasers. Your one-time purchase guarantees access to all future additions and improvements to this collection.

Historical Note

Hispano-Suiza — formally the Société Française Hispano-Suiza, headquartered at Bois-Colombes, France — is best known for its legendary V8 and V12 inline engines, but in the early 1930s the company pursued an ambitious radial programme based on licensed Wright technology. The 9-cylinder Hispano-Suiza 9V (also known as the Hispano-Wright) derived from the Wright R-1820 Cyclone, while the 14-cylinder twin-row series split into two distinct families: the compact 14AB (Type 80, 1,590 cu in / 26.05 L, ~637–671 hp) licensed from the Wright Whirlwind lineage, and the larger 14AA (Type 79, 2,761 cu in) derived from the Wright R-2600 Cyclone.

Development and licensing began in the late 1920s, with production running from approximately 1930–1932 through to 1940. Around 2,500 units of the 14AB series alone were produced. The 14AB powered key French combat aircraft including the Breguet 693 attack bomber, the Loire-Nieuport LN.401 naval dive bomber, and the Potez 63 series multi-role aircraft. The 9V equipped various French courier and light transport types. In operational service during the Battle of France (1939–1940), the 14AB suffered from persistent cooling difficulties that ultimately led to its replacement by the Gnome-Rhône 14M in several airframes. Post-war use was limited; surviving engines are today found exclusively in museum collections. Hispano-Suiza's aviation assets were eventually absorbed into what is now the Safran Group.

Manuals Included in This Collection

• Hispano-Suiza 14AA Aircraft Technical Manual — Instruction Book — 1932 (French Language)
• Hispano-Suiza 14AA Aircraft Technical Manual — Instruction Book (French Language)
• Hispano-Suiza 9V Aircraft Engine Maintenance Manual — Instruction Book (French Language)

This collection covers the principal 9-cylinder and 14-cylinder twin-row variants produced by Hispano-Suiza during the 1930s, spanning factory instruction books and maintenance procedures as issued to French military and civil operators of the period.

Engineering Norms and Standards

The Hispano-Suiza 14AB was built to French military specifications of the era, with a 14-cylinder twin-row air-cooled configuration, 135 mm bore × 130 mm stroke, 6:1 compression ratio, single-speed supercharger, and cast aluminium cylinder heads. Fuel requirement was 87-octane. Dry weight was approximately 495 kg (1,091 lbs). The 14AA shared the twin-row architecture but with significantly greater displacement (2,761 cu in) and a slightly higher compression ratio of 6.2:1. Both variants were manufactured to French Armée de l'Air procurement standards of the late 1930s. No active Type Certificate, Service Bulletins, or Airworthiness Directives apply — these engines are of historical and archival significance only.
