On October 17, 1979, IPTN and CASA (now Airbus Defence & Space) estabilished a new joint-venture company, Aircraft Technology (Airtech) to design the CN235. This new multi-purpose aircraft has a Short Take-Off and Landing (STOL) capability at 800 meters rugged airstrips, ramp door for easy loading / unloading, and low cost maintenance characteristic.
The first prototype “Elena” produced by CASA made its maiden flight on November 11, 1983 and the second prototype “Tetuko” produced by IPTN (now PTDI) flew for the first time on December 1983. The serial production began in 1986 for the 10 and 100 versions.
Later on PTDI developed the improved version, such as 110 and 220 versions; while Airbus Defence & Space with its 200 and 300 versions. Up to the present time, more than 300 CN235s have been produced in many versions with the latest two General Electric CT7-9C engines (each has 1,750 SHP).
In the collaboration, for export purpose, PTDI manufactures the outer wings, horizontal stabilizers, vertical fins and doors for Airbus Defence & Space; while Airbus Defence & Space produces disassembled noses, disassembled cockpit, and center wings for PTDI.
