The prototype Bell 230, C-GEXP, on a test flight over Mirabel Airport on Sep. 11, 1991. After 222B/222UT production ended in the late 1980s, Bell relaunched the line in Mirabel, Quebec as the Model 230 with RR/Allison 250-C30 engines replacing the 222's LTS101s. Two original 222B and 222UT prototypes became 230 prototypes. C-GEXP was originally a 222UT (msn 47503, N3177U and later N35AZ). The first 230 prototype flew on August 12, 1991. This airframe later received a cabin stretch and 4-blade rotor to become a Bell 430 prototype. It's been displayed for many years in front of the Bell Helicopter Textron Canada plant.
