The Maestranza Central de Aviación HF XX-02 was a military trainer aircraft developed in Chile in the 1950s. It was a conventional, low-wing cantilever monoplane of mixed construction with fixed tailwheel undercarriage. The pilot and instructor sat side-by-side. Two prototypes were constructed at El Bosque Air Base, designated XX-02 and XX-02B after which development was abandoned due to difficulties maneuvering at lower altitudes. In one case, this led to a crash in which the instructor was killed while attempting to land after a tight turn at low altitude.
