Aeronáutica Industrial S.A. is a Spanish aeronautical company. The predecessor company, Talleres Loring had been founded by Jorge Loring in 1923.
History
The predecessor company was founded by Jorge Loring Martinez in Cuatro Vientos near Madrid in 1924. Aeronáutica Industrial S.A. was established in 1934 and through the course of the 20th century manufactured a number of light aircraft designs including Cierva autogyros.
In 1954, AISA purchased Spanish manufacturer Iberavia and took over the I-11 light plane project, eventually building around 400 examples. For a time it specialised in the maintenance and upgrading of helicopters. In 1982 it attempted, unsuccessfully, to market an autogyro design of its own, the GN.
The company was bought by CASA in 1995, but continues to operate under its own name.

AISA I-11

I-11
Role - Two-seat general aviation aircraft
Manufacturer - Iberavia/AISA
First flight - 16 July 1951
Number built - 208
Variants - AISA I-115

The I-11 was a two-seat civil utility aircraft manufactured in Spain in the 1950s. Originally designed by the Spanish aircraft company Iberavia, its first (of two) prototype flew on 16 July 1951. It was a low-wing monoplane of conventional configuration with fixed, tricycle undercarriage and a large, bubble canopy over the two side-by-side seats. Flight characteristics were found to be pleasing, but before plans could be made for mass production, Iberavia was acquired by AISA.
The new management decided to continue with development, but made a few changes to the design, reducing the size of the canopy, and replacing the undercarriage with a taildragger arrangement. This configuration entered production in 1952 with an order from the Director General for Civil Aviation for 70 aircraft for use in Spain's aeroclubs. The Spanish Air Force then ordered 125 for use in training and liaison roles.
The Air Force then requested 200 aircraft built with the seats in tandem, which were designated I-115 by the manufacturers powered by a 112 kW (150 hp) ENMA Tigre inverted air-cooled engine.

Role - Basic trainer
National origin - Spain
Manufacturer - AISA (Aeronáutica Industrial S.A.)
First flight - 20 June 1952
Introduction - 1956
Retired - 1976
Primary user - Spanish Air Force
Number built - c.200
Developed from - AISA I-11

The AISA I-115 is a low-wing single-engined military primary trainer with tandem seating, which went into service with the Spanish Air Force in 1956. After retirement in 1976 many were sold to civil operators.
Development
The AISA I-115 was a military development of the single-engined civil side-by-side seat I-11 which first flew in 1951. This aircraft was designed by Iberavia but built by Aeronáutica Industrial S.A. (AISA); later, Iberavia were taken over by AISA. The I-115 inherited the tail wheel undercarriage of the production version of the I-11, the I-11B, but was a longer machine because the Spanish Air Force wanted tandem seating for its trainers, had a slightly greater span and was considerably heavier. These changes called for more power, so the I-115 used a 112 kW (150 hp) ENMA Tigre inverted in-line engine.
Like the I-11 the I-115 had an all wood structure and most surfaces were plywood covered apart from fabric covered ailerons and flaps. The low, tapered, straight edged and square tipped wings had two spars and stressed plywood skin. Wing dihedral was 6°. The ailerons were differentially operated and drooped when the slotted flaps were lowered. The vertical stabiliser was almost rectangular and carried a balanced rudder. The horizontal tail surfaces were more tapered, the elevators balanced and carrying trim tabs. The fuselage was a wooden monocoque. The tandem cockpits were enclosed with a long, glazed cover with independent sliding sections for both instructor and pupil. Dual controls and instrumentation included provision for blind flying. The undercarriage was fixed and unfaired, each mainwheel carried on a single exposed leg. The mainwheels had brakes and the tailwheel was steerable.
The first prototype flew on 20 June 1952.
Operational history
About 200 I-115s were delivered to the Spanish airforce, 150 by the Spring of 1956; at that time there was an order for another 150. They were initially known as the type EE.6, EE being Escuela Elemental or Primary Training, but when this category was dropped the I-115 became the E.9 (E for - Entrenamiento or Trainer). The E.9 was in service from 1956 to 1976. Despite the long service, there was criticism of its spinning behaviour and its weight: apparently the unofficial nickname Garrapata or Tick was meant to describe the E.9's reluctance to leave its host, the ground. Most E.9s were powered by the Tigre engine but some late models had the 145 hp de Havilland Gipsy Major engine and others a 190 hp Lycoming O-435-A.
Many I-115s were sold to civilians at the end of their military service and in 2014 seven were still on the Spanish civil register. Three of these were in museums but were active until at least 2009.

González Gil-Pazó GP-1
(AISA GP-1)

González Gil-Pazó GP-1
Role - Two-seat trainer
National origin - Spain
Designer - Arturo González Gil y Santibañez and José Pazó
First flight - June 1934
Number built - c.40

The González Gil-Pazó GP-1 was a single-engine, two-seat open cockpit training aircraft, built in Spain in the 1930s to compete for a government contract. Declared the winner, production was curtailed by the Spanish Civil War. Two cabin variants, the González Gil-Pazó GP-2 and GP-4, were also built.
Design and development
The first aircraft produced from the collaboration between Arturo González Gil y Santibañez and José Pazó was the Gil-Pazó No.1. It was, like all of their aircraft, a low-wing cantilever monoplane. It was built of wood and metal with plywood skinning, seated two and had an unfaired conventional undercarriage. Reportedly similar to the Miles Hawk, it was powered by an ADC Cirrus engine. Almost no specifications are known, apart from a loaded weight of 778 kg (1715 lb). It first flew in June 1932 and was last recorded at Cuatro Vientos, Madrid in July 1936.
In 1934 the Director General de Aeronáutica issued a specification for a two-seat trainer and Gil-Pazó's response was the GP-1. This "supremely elegant" aircraft, with two open cockpits and a trousered undercarriage was reportedly somewhat like the Miles Hawk Major in appearance. Its wings, of semi-elliptic plan, had a wooden structure and a stressed plywood skin. Flaps were fitted. The fuselage was a steel tube structure, fabric covered at the rear with dural skinning forward. For its first flight in June 1934 it was powered by the same Cirrus engine as the No.1 but this was replaced by a 145 kW (195 hp) Walter Junior inverted inline engine for the trainer contract competition.
The competitive trials, against the Loring X, the Hispano HS-34 and the Adaro 1.E.7, assessed the Gil-Pazó GP-1 as the clear winner, so in 1936 González Gil and Pazó received an order for 100 aircraft. These were to be built by Aeronáutica Industrial S.A. (AISA), the former Talleres Loring factory at Carabanchel Alto, Madrid. None of these had been completed by July 1936 at the start of the Spanish Civil War, and with rebel forces approaching Madrid in October, AISA retreated to Alicante. About forty GP-1s were built there during the war in a collaboration with Hispano-Suiza.
In 1935-6 the open cockpit GP-1 was developed into two cabin types, the González Gil-Pazó GP-2 and GP-4. Both had raised rear fuselages faired into the cabin tops. The GP-2 was powered by a 97 kW (130 hp) de Havilland Gipsy Major engine and had two seats in tandem. Only one two-seater was built. A second GP-2 was built as a single-seater with one, rather than two, cabin side windows on each side. The GP-4 was powered by a 97 kW (130 hp) Walter Major engine and carried four people. Only one GP-4 was constructed.
Operational history
Two notable flights were made before the Civil War. In January 1936 Ramón Torres and Carlos Coll set a record with their flight from Barcelona to Agadir, Morocco in the two-seat GP-2. The single-seat GP-2 was flown by Lorenzo Richi in March 1936 from Madrid to Bata in what was then Spanish Guinea at an average speed of 187 km/h (116 mph).
About thirty of the forty GP-1s built at Alicante were captured by the Nationalist forces, given military serials and incorporated into Grupo 30. After the war at least twelve of these were given Spanish civil registrations; one remained on the register until 1961.
One GP-2 and the sole GP-4 were also on the Spanish civil register until about 1960. The GP-4 had been flown into Nationalist hands by Pazó in September 1936, where it was used for liaison and transport duties.
