Blackhawk Aerospace is developing a supplemental type certificate (STC) to re-engine the Daher TBM 700 series with 150 more shaft horsepower, in partnership with sister company and TBM-authorized sales and service center Avex Aviation. The STC will replace the 700-shp Pratt & Whitney Canada PT6A-64 on the TBM 700A, 700B, and 700C2 with the 850-shp PT6A-66D.

Performance of the re-engined TBM 700 will be boosted to that of the TBM 850, according to Blackhawk. Time to climb to FL310 for the PT6A-66D-powered TBM 700 drops to 14 minutes from 16 minutes 39 seconds, and maximum cruise speed ranges from 287 to 307 ktas, improving overall efficiency and adding to safety margins.
