It has a pair of turbocharged-piston engines, each driving a three-bladed propeller on either side of the central fuselage, underneath a straight high-mounted wing.

In the first encounter, the TB-001 flew over the East China Sea unaccompanied, and in the second encounter it flew through the Miyako Strait alongside two Shaanxi Y-9 aircraft.
