Premier Aircraft of East Alton, Ill., continues to work with Honeywell on an engine upgrade program for the Falcon 50 expected to be completed in the third quarter of next year, several months later than originally planned. The program will convert the original Falcon 50 TFE731-3 engine to a TFE731-4 to provide the "Falcon 50-4" with longer range, increased hot-and-high performance, better climb capability and higher cruise thrust than the basic aircraft, according to Premier Aircraft. As an incentive to spur initial orders, Premier is offering the first 10 customers $50,000 off the cost of the upgrade. The price is $2.3 million for non-MSP aircraft. For an operator whose aircraft is on MSP (which is the majority of the fleet), pricing is about $1.6 to $1.7 million. Loaner engines will be available to reduce downtime, estimated at about 45 to 60 days.
