The CASA/IPTN CN-235 is a medium-range twin-turbo-prop aircraft developed jointly between CASA in Spain and IPTN in Indonesia as a regional airliner and military transport. Amongst its military roles are maritime patrol, surveillance and troop transport. The largest user is Turkey which has a total of 61 aircraft.
Design and development
The project was a joint venture between CASA and Indonesian manufacturer IPTN, which formed Airtech company to manage the programme. Responsibility for design and production was shared at 50% between the two companies. The partnership applied only to the Series 10 and Series 100/110, with later versions being developed independently.
Design began in January 1980 with first flight on 11 November 1983. Spanish and Indonesian certification was on 20 June 1986; the first flight of the production aircraft was on 19 August 1986 and FAA type approval was granted on 3 December 1986. The aircraft entered service on 1 March 1988
In 1995, CASA launched development of a stretched CN-235 as the C-295
The CN-235 was selected by the United States Coast Guard for its Medium Range Surveillance Maritime Patrol Aircraft (MRSMPA) program as the HC-144A . The first HC-144A was delivered by EADS CASA to Lockheed Martin for installation of the mission package in December 2006.
In August 2006, three CASA CN-235-10 aircraft remain in airline service, in Africa, with Safair (two) and Tiko Air (one). Asian Spirit operates a sole CN-235-220 in the Philippines, correct as of June/July 2007.
The Irish Air Corps operates two CASA aircraft in the maritime patrol capacity.
There are at least two CN-235s operating with the United States Air Force for an undisclosed role with the 427th Special Operations Squadron, at the former Pope AFB, NC.
In early July, The Mexican Navy announced they will order six CASA CN-235 from Spain.
