Blackhawk XP135A Engine Upgrade for the King Air 90 series

The Blackhawk XP135A is a simple, bolt-on upgrade for the King Air 90 series that requires no airframe modification. The original, early generation engines are exchanged for factory-new Pratt & Whitney PT6A-135A engines with Pratt & Whitney's 1000 hour, no calendar limit, engine warranty. The Blackhawk XP135A  enjoys an increased true airspeed and maximum range with a lower time to climb and lower operating and maintenance cost.
