The baseline Challenger 300 performed its maiden flight on 14 August 2001 and received its Canadian type approval on 31 May 2003; it commenced commercial operations on 8 January 2004.[3] During the late 1990s, Bombardier Aerospace decided to embark on the development of a super mid-sized business jet that would be positioned between its existing Learjet 60 and the Challenger 604.[8] In late 1998 and early 1999, various key suppliers, such as Rockwell Collins and AlliedSignal, the former providing its Pro Line 21 integrated avionics system and the latter producing the AS907 turbofan engine selected to power the type, agreed terms for their involvement in the project.[16][7][17] In November 1999, it was announced that the programme was proceeding ahead of schedule, having reached its first production milestone that same month;[18] final assembly was performed in Montreal, Quebec.[30] During 2018, 60 Challenger 350s were delivered as Bombardier claimed a 58% market share of the super mid-size segment, and the 300th delivery was reached in July 2019, after five years of service.[29] Canted winglets have a less acute angle that reduces transonic drag and enlarge the span by 5.2 ft (1.6 m), increasing wing area and aspect ratio.[32] The flight deck of the aircraft is provisioned with Rockwell Collins Pro Line 21 avionics include four LCD displays, an EICAS and Maintenance Diagnostics Computer, an EGPWS, a TCAS II and an ELT.[40] On the Challenger 350, the primary flight display (PFD) fills the full width with the attitude directional indicator (ADI) symbology and synthetic vision system (SVS) imagery.[42] During 2022, the United States Federal Aviation Administration (FAA) ordered pilots to perform additional safety checks on the model after "multiple incidents" in which a horizontal stabilizer malfunctioned.[43] In 2023, a passenger was killed by blunt force trauma in a Challenger 300 inflicted when a series of automated pilot instructions resulted in the stabilizer control system being turned off, causing the aircraft to pitch violently.[43][44] On December 18, 2024, a Bombardier Challenger 300 with tail number LV-GOK, flying from Punta del Este, Uruguay landed in San Fernando airport, Buenos Aires, Argentina, went off course and crashed into a neighboring house, completely destroying the plane Both crew members died as a consequence of the fire.
