US-based Blackhawk Modifications is celebrating the sale of its 150th XP61 engine upgrade for the Beechcraft King Air B200.
Operator South Coast Air Charter, based at the UK's Southampton airport, will be the recipient of the milestone powerplants on its Super King Air B200 (G-JOAL).
Under the upgrade package, Blackhawk will replace the type's engines with new Pratt & Whitney Canada PT6A-61 turboprops.
Alison Steel, director of South Coast Air Charter, says: "The upgrade will improve the aircraft's reliability and efficiency, while adding an increased safety margin in flight operations."
MCA Aviation will install the powerplants at its Shoreham-by-Sea site in the UK.
The performance advantages of the XP61 upgrade include an improved rate of climb with lower fuel consumption, a higher single-engine service ceiling, and an increase in true air speed.
Blackhawk was celebrating a further milestone at the show, with the sale of its 375th engine upgrade package - the XP42A system on a Cessna Grand Caravan (G-DLAC) operated by Isle of Man-based charter business Aerodynamics.
This sees the installation of a new P&WC PT6A-42A engine, a wide-chord 2.54m (100in) Hartzell four-blade propeller, a composite engine cowling and a number of other modifications.
