The PA-20 Pacer and PA-22 Tri-Pacer are a series of four-seat propped shoulder- wing planes that were built by the US Piper Aircraft after the Second World War . The Pacer is basically a four-seat version of the two-seat Piper Vagabond . It has a fuselage made of steel tubes and wings made of a fabric-covered aluminum frame. This means that its construction is similar to the well-known Cub and the Super Cub . Many Pacers are still in use today because of their insensitivity, the spacious cabin and the speed that was impressive at the time.
The aircraft were powered ex works by engines with outputs of 125 PS (92 kW), 135 PS (99 kW), 150 PS (110 kW) and 160 PS (118 kW). Some examples were later converted and equipped with an engine with 180 hp (132 kW).
development
The Piper PA-20 was originally equipped with a tail wheel landing gear and therefore offered a somewhat restricted view and required more skill when taxiing . To offer pilots more safety, Piper presented the PA-22 Tri-Pacer in February 1951, which had a nose wheel landing gear instead of the tail wheel landing gear .
Pacer and Tri-Pacer belong to a group of Piper aircraft called "Short Wing Pipers". In contrast to the Pacer, whose most powerful engine option had 135 hp (99 kW), the Tri-Pacer was also delivered with engines with 150 hp (110 kW) and 160 hp (118 kW). Over time, the tricycle landing gear configuration became increasingly popular, and in 1953 Tri-Pacer sales exceeded the Pacer six to one. Due to the appearance of the chassis, the Tri-Pacer was nicknamed the "Flying Milk Stool" - "Flying Milking Stool "
In 1959 and 1960 Piper offered a less equipped version of the Tri-Pacer with a Lycoming O-320 engine with 150 PS (110 kW) under the name PA-22-150 Caribbean. Over 9,400 Tri-Pacers were built between 1950 and 1964, and 3,280 were still registered in the United States as of April 2018.
The Tri-Pacer had an extraordinary feature. Her ailerons and rudder were connected to each other with rubber ropes. This simplified the coordination during flight maneuvers and could easily be overridden by the pilot if necessary. Furthermore, a simplified form of an autopilot made it possible, which Piper marketed under the name "Auto-control". A small number of PA-22s were converted to tail-wheel aircraft, making them very similar to the PA-20 Pacers, but retaining the improvements and other features of the PA-22. These conversions are often referred to as the PA-22/20, although the Federal Aviation Administration's official designation remains the PA-22 Tri-Pacer. With such modifications, the factory drum brakes are normally exchanged for disc brakes . A Lycoming O-360 with 180 hp (132 kW) is the preferred drive.
Some PA-22 have a fixed speed propeller from Hartzell or are equipped with Koppers Aeromatic propellers. This increases the performance of the aircraft at the expense of the payload.
With the PA-22-108 Colt, a school version of the Tri-Pacer was introduced. This was to compete directly with other popular training aircraft of the time such as the Cessna 150 and is powered by a Lycoming O-235 with 108 hp (79 kW). Over 2000 Colts were built within a two-year production period. Some Colts were also converted to the tail wheel configuration, although this conversion was not as popular as converting Tri-Pacers. The last batch of twelve PA-22-150s were built in 1963 for Aviation légère de l'armée de Terre , the French Army Aviation Unit, and the last PA-22-108 Colt left the factory on March 30, 1964. After that, the PA-28 Cherokee 140 replaced the pattern.

use
Cuba
Between 1953 and 1955, the Fuerzas Armadas Revolucionarias bought seven PA-20s, four PA-22-150s and three PA-22-160s. During the Cuban Revolution , the rear doors of the PA-22 were removed and 7.62 mm caliber machine guns were installed. Modified in this way, the machines were used against insurgents. A PA-22 that provided ground support to the Cuban Army during the Battle of Guisa is the only aircraft that the FAR lost to enemy fire.
Katanga
During the Congo Crisis , Katanga Separatists received five PA-22-150s from the South African Air Force . They were used against forces of the United Nations Operation in the Congo between 1961 and 1963. The whereabouts of the machines after the conflict is uncertain.
