What Happens During an Engine Overhaul?
Key Section Cleaning
During an engine overhaul, all major components are disassembled, cleaned, inspected, reassembled, and tested. Key sections include:
- Accessory Gearbox
- Gas Generator Section
- Power Section
- Reduction Gearbox
Engine accessories overhauled include the fuel control unit, fuel pump, fuel nozzles, fuel flow divider, fuel oil heater, constant speed governor, heated tubes, and ignition unit. Mandatory service bulletins are incorporated during the overhaul, and optional bulletins can be addressed if requested.
Hot Section Inspections
Hot section inspections ensure all critical engine components—such as turbine blades, compressor inlet, and CT shroud segments—perform efficiently and safely.

Engine Upgrades
King Air C90
C90 operators have several engine upgrade options. Blackhawk offers the XP135A, which increases airspeed and lowers operating costs. GE Aviation provides the H17 engine, rated at 750 shaft horsepower, delivering faster cruise speeds with reduced fuel burn. Additionally, the Pratt & Whitney PT6-135A, also rated at 750 shaft horsepower, is available for both the C90 and F90. Any of these upgrades can boost cruise speed by 20–30 knots, giving operators improved performance and efficiency.
King Air 200
For the King Air 200, three engine upgrades are available: the Pratt & Whitney PT6A-42, PT6A-52, and PT6A-61. These engines can replace the original PT6A-41, offering operators increased performance. The -42 is the most cost-effective option, providing modest speed gains while replacing an older engine with a newly manufactured one. The -52 and -61 models deliver more performance, with cruise speed increases of approximately 26 knots for the -52 and 17 knots for the -61, allowing operators to choose the balance between cost and performance.
King Air 350
Blackhawk’s XP67A upgrade is now available for the King Air 350. This package promises a faster rate of climb, improved takeoff performance in high and hot conditions, higher cruise speeds, and an increased single-engine service ceiling. The upgrade includes two new MT five-blade composite propellers, enhancing overall efficiency and giving operators a new, modern, high-performance engine solution.
