Aero Industry Development Centre (AIDC) AT-TC-3 Tse Tchan / AT-3


With development and design by AIDC begun in 1975, with assistance from Northrop, the first XAT-3 prototype flew on September 16, 1980. The aircraft is a twin-turbofan tandem-seat trainer with an unswept wing of supercritical section. Power is from two Garrett TFE731 engines, each giving 15.57kN thrust. For weapons training and light attack duties a semi-recessed gun pack with twin 0.5in machine-guns can be installed in a weapons bay beneath the rear cockpit, and external stores can be carried on four under-wing and one under fuselage hardpoints. Wing-tip launch rails for AIM-9J Sidewinders are provided. Total external weapons avaiable load is 2,720kg (6,000lb). An A/A37U-15TTS aerial target system can be carried on the centreline pylon.

Deliveries of the AT--TC-3 to the Republic of China Air Force began in March 1984, and more than 50 were on order for use as basic and advanced trainers, replacing the Lockheed T-33 trainers. Production aircraft totaling 60 were delivered from 1984 through 1990.
