On October 17, 1979, IPTN and CASA (now Airbus Defense & Space) established 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 out/coming goods easily, and low cost maintenance characteristics.
The first prototype “Elena” produced by CASA made the 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 Defense & Space with 200 and 300 versions. Nowadays, 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 produces outer wings, horizontal stabilizers, vertical fins and doors for Airbus Defense & Space; while Airbus Defense & Space produces disassembled noses, disassembled cockpit, and center wings for PTDI.
