About Engine Overhauls

During an engine overhaul, all portions of the engine are disassembled, cleaned, inspected, reassembled, tested (ensure the facility you will be using has an appropriate test cell to run the engine off wing through all parameters) and shipped back to the installation agency. The engine consists of four major sections as follows: Accessory Gearbox, Gas Generator section, Power Section and Reduction Gearbox. Engine accessories that will also be overhauled at that time are as follows: Fuel control unit, fuel pump, fuel nozzles, fuel flow divider, fuel oil heater, constant speed governor, heated tubes and ignition unit. During the overhaul, and any mandatory service bulletins can be embodied. It is also a time when any optional service bulletins may be reviewed and completed if a customer elects to do so.

About Hot Sections

During a Hot Section Inspection, all hot section engine components are inspected to make sure they can generate enough power for efficiency and safety. This includes turbine blades, compressor inlet, CT shroud segments and more.

Engine Upgrades

King Air C90

For the C90 there are a couple of choices for engine upgrades. Blackhawk offers an XP135A upgrade that provides an increased airspeed and reduced operating costs. GE Aviation offers the H17 engine, which boasts 750 shaft horsepower. This increases the cruise speed, while allowing for a reduced fuel burn. Another choice for both the C90 and F90 is the Pratt & Whitney PT6-135A engine. This engine is also rated at 750 shaft horsepower. Operators can expect a 20 to 30 knot increase in cruise speed for any of these engine upgrades.  

King Air 200

For the King Air 200 users, there are three engine upgrade options, the Pratt & Whitney PT6A-42, PT6A-52, and PT6A-61. For the King Air 200 operator, the original Pratt & Whitney PT6A-41 engines can be fitted with any of these engines.

For King Air 200 operators, it can make a lot of sense to upgrade to the -42 engine, rather than overhauling their existing -41 engines. This is the least expensive of the three options, and provides modest performance gains. However, the biggest benefit is that it replaces a 30-40 year old engine with a newly manufactured one.

The other engine upgrade options are for a -52 or -61 model. These two engines are very similar, with the -52 providing a slight cruise speed increase over the -61. In either case, you can expect to realize a 17 kt. increase in cruise speed for the -61, and a 26 kt. increase for the -52.  

King Air 350

Although engine upgrades are not currently available, Blackhawk’s XP67A engine upgrade is currently in the works. It is expected for this upgrade to have an increased rate of climb, shorter high/hot take-offs, faster cruise speeds and higher single engine service ceiling. The installation will include two factory new MT five blade composite propellers.
