Pratt & Whitney Canada was selected in October 2001 to power the new Falcon with its PW307A, a member of the PW300 series that includes the PW308C powering the Falcon 2000EX. For the 7X, the first three-engined application for P&WC and the first for a long-range business jet, the manufacturer delivers an integrated powerplant system including engine mounts, nacelles and thrust reversers.

First engine run was in December 2002, with more than 4,000h running time to date, including 450h on P&WC's two Boeing 720 flying testbeds. The first engine shipset was delivered on schedule in July 2004.

The PW307A produces 7,500lb thrust (33kN) at take-off and is flat-rated to 6,400lb. Basic architecture matches the rest of the PW300 family, but includes a new "shock management" fan with increased flow capacity, more efficient powdered metal high-pressure turbine discs and P&WC's new low-emissions combustor.
