Under the Lockheed name, designed by the Mooney brothers as a single-engine light transport aircraft in the same general class as the Cessna 180-185, it made extensive use of castings and forgings for ruggedness and simplicity. The wing is NACA 23016 at the root and NACA 4412 at the tip. Lockheed flew the first prototype on 15 September 1959. As its massive overheads in its main factories would price the six-seat aircraft out of its intended market, Lockheed looked for licensees in other countries for production. A new factility was purpose-built for Lockheed-Azcarate SA at San Luis Potosi, Mexico, where the LASA-60 was produced.
The prototype Lockheed-Azcarate LASA 60 was certificated early in 1960, and registered in Mexico.
The first Mexican built LASA-60 flew on 21 March 1961. Eighteen LASA 60 built in Mexico in 1960 were for the Fuerza Aerea Mexicana until the withdrawal of that type in 1968 69. They were delivered to the Mexican Air Force’s No.209 Search and Rescue Squadron.
Plans for manufacture by Lockheed-Kaiser in Argentina were abandoned. The main licencee was Italy’s Aermacchi who acquired exclusive manufacturing rights.
Designated AL,60, the first Aermacchi-built aircraft flew on 19 April 1961, the basic production model being the AL 60B-1.
The AL 60B-2 was powered by a turbo-supercharged 260 hp Continental TSIO-470-B engine.
The AL.60C featured an up-rated engine and a parachute door. Flown for the first time in prototype form in early 1963, the AL 60C-4 the C-4 featured a tail wheel undercarriage and was the most powerful yet flown. The AL 60C-4 evolved to meet Italian Air Force requirements for parachute training, the dropping of supplies, and a sturdier undercarriage for rough field operation. Accommodating up to six persons, the AL 60C-4 has duplicate freight doors and an additional door for pilot entry. Apart from the doors, engine and undercarriage, the AL 60C-4 is essentially similar to other versions, and is of all metal construction with a D-spar torsion box wing structure and a semi-monocoque fuselage.
With a tail wheel, as the AL.60 C-5 Conestoga, which 10 were supplied to the Central African Republic from 1971 (two remaining in late 1997) and Mauretania (one remaining in late 1997).
The AL 60D-3 was powered by a 310 hp Continental GIO-470-A engine.
The AL.60F-5 version with nose wheel undercarriage was sold to the Rhodesian Air Force.
Other variants were made under license in South Africa.
