The CASA/IPTN
CN-235 is a medium-range twin-engined transport plane that was jointly
developed by CASA of Spain and IPTN of Indonesia as a regional airliner and
military transport. Its primary military roles include maritime patrol,
surveillance, and air transport. Its largest user is Turkey which has 61
aircraft.
Design
and development
The project
was a joint venture between Construcciones Aeronáuticas SA (CASA) and
Indonesian manufacturer IPTN, which formed the Airtec company to manage the
programme. The partnership applied only to the Series 10 and Series 100/110,
with later versions being developed independently. Over 230 of all versions of
CN-235 are in service and have accumulated more than 500,000 flight hours.
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. In December 2002, the
Colombian Navy ordered two CN-235 for patrol and anti-drug trafficking
missions.
In April
2005, Venezuela ordered two CN-235 maritime surveillance aircraft plus 10
transport planes but the operation was halted due the United States refuse to
allow US technology to be transferred.
In January
2006, Thailand placed an order with Dirgantara for ten aircraft, six for the
Ministry of Defence and four for the Ministry of Agriculture.
In December
2007, Spain ordered two CN-235 maritime patrol aircraft for the Guardia Civil,
for delivery 2008–2009.
One CN-235
MPA aircraft was delivered by Dirgantara to the Indonesian defence ministry in
June 2008.
In August
2006, three CASA CN-235-10 aircraft remain in airline service, in Africa, with
Safair (two) and Tiko Air (one).[2] Asian Spirit operates a lone CN-235-220 in
the Philippines, correct as of June/July 2007.
The Irish Air
Corps operates two CASA aircraft for maritime patrol duty.
There are at
least two CN-235s flying with the United States Air Force for an undisclosed
role with the 427th Special Operations Squadron, located at the former Pope
AFB, North Carolina.
In early July
2008, the Mexican Navy announced that it will purchase six CASA CN-235s from
Spain. In April 2010, Hervé Morin, French Minister of Defence, announced the
order of eight CN-235-300s from Spain.
In 2011, PT
Dirgantara Indonesia is still working on 4 CN-235-110 MPAs for South Korea
