 The Pacific Aerospace Corporation CT/4 Airtrainer series is an all-metal-construction, single-engine, two-place with side-by-side seating, fully aerobatic, piston-engined, basic training aircraft manufactured in Hamilton, New Zealand.

The Airtrainer design is of cantilever low-wing monoplane configuration, with a fixed tricycle landing gear. It has interconnected ailerons and flaps, with both systems functioning as both ailerons and as flaps when operated. The nosewheel was steerable. The CT/4 prototype first flew on 23 February 1972. A total of 155 aircraft had been built by 2024.		   Die CT/4 Airtrainer-Serie der Pacific Aerospace Corporation ist ein vollständig aus Metall gefertigtes, einmotoriges, zweisitziges, voll kunst-flugtaugliches Basistrainerflugzeug mit Kolben-motor, das in Hamilton, Neuseeland, hergestellt wird.
Das Design des Airtrainers ist eine freitragende Tiefdecker-Konfiguration mit einem festen Dreirad-fahrwerk. Es verfügt über miteinander verbundene Querruder und Klappen, wobei beide Systeme bei Betätigung sowohl als Querruder als auch als Klappen fungieren. Das Bugrad war lenkbar. Der Prototyp des CT/4 flog erstmals am 23. Februar 1972. Bis 2024 wurden insgesamt 155 Flugzeuge gebaut.
