On 10 May 1991, the first of three development aircraft for the initial CRJ100 variant performed its first flight from Montréal–Pierre Elliott Trudeau International Airport, starting a 1,000h flight test program with three prototypes.[9] During the following year, the type was awarded airworthiness certification; on 29 October 1992, initial deliveries to customers occurred later on that year.[3] On 26 July 1993, the first prototype (C-FCRJ) was lost in a spin mishap near the Bombardier test center in Wichita, Kansas.[10][11]
