TYPE: Twin-turboprop amphibian.

PROGRAMME: Introduced as product follow-on to piston-engined Canadair CL-215; given new designation Canadair 415 in 1991 to distinguish new production turboprop model from CL-215T retrofit, but engineering designation retained and new-build turboprop versions are CL-215-6B11. Launched officially 16 October 1991 with firm orders from France and (August 1992) Quebec; first flight (C-GSCT) 6 December 1993, although preceded by initial GL-215T conversion (C-FASE), flown on 8 June 1989. Canadian certification 24 June 1994 in Restricted and Utility categories, FAA approval 14 October 1994 in Restricted category. RAI (Italy) approval 27 October 1994 in Restricted category. Fleet had achieved 50,000 flying hours and 190,000 scooping sorties by 31 March 2001. Final assembly relocated to North Bay, Ontario, in November 1998. Production suspended in October 2001 pending new orders. New designation Bombardier 415 adopted in February 2002.

CURRENT VERSIONS: Standard 415 and first production units are in firefighting configuration.
415MP: Multipurpose version incorporating FLIR, SLAR and nose-mounted search radar for missions such as search and rescue, coastal and border patrol and environmental monitoring, while retaining firefighting capability. First flight (C-GHVX; 55th aircraft, destined to become 415GR for Greece) 6 March 2002, preceding a 200-hour flight test programme.
415MP can be modified for maritime, SAR and special missions.
415GR: Ordered by Greece, January 1999; based on 415MP; increased weights; boat handling and cargo hoisting provisions. Two (plus an optional third) will be configured for combat search-and-rescue (C-SAR) role, for which, during 2000, SAAB Nyge Aero of Sweden was awarded a three-year contract to install MSS 5000 mission equipment including SLAR (each side), wing-mounted FLIR Systems SeaFLIR, nose-mounted Honeywell Primus WX 660 weather/search radar, digital cameras, autopilot and provision for Have Quick secure radios and rescue beacon receivers. The aircraft will also have an enlarged cargo door to facilitate deployment of an inflatable rescue boat. The Hellenic Air Force C-SAR aircraft will be based at Elefsis AB; delivery was due in May 2003.

CUSTOMERS: First French Canadair 415 delivered to CEV experimental unit 8 February 1995, but trials revealed need for modifications and acceptance delayed until 13 June 1995; deliveries completed June 1997. Ontario provincial government announced order for nine on 2 April 1998. Government of Malaysia expressed interest in acquiring two following demonstration flights in February 2002. Total 59 built by October 2001 production suspension; 60th registered in January 2002, but none further in that year.

COSTS: Approximately US$23 million in firefighting configuration (2000).
