Pratt & Whitney T74-CP700 (PT6A-20) 550-SHP Turboprop Engines
Distinguished only by the serial numbers and model numbers that were assigned to the engine during production, the Pratt & Whitney T74-CP700 engine is the military version of the world-renowned Pratt & Whitney PT6A-20 as used on Beechcraft King Air 90s, DeHavilland Twin Otters and other aircraft.
The T74-CP700 engines were operated by the U.S. Army on Beechcraft King Air U21 aircraft that were used for VIP transportation and electronic countermeasure operations. Maintained by Beechcraft (BASI) from 1986 until release from the military in 1997, all work on the engines was performed under a FAA repair station license.
At long last, an affordable “PT6” is now available from Dynamic Aviation. This is the ultimate engine for experimental aircraft! Consider these details:
- 550-SHP for only 286 pounds – nearly a 2:1 power to weight ratio.
- Fuel consumption of 35 gallons/hour below 10,000 feet, and approximately 30 gallons/hour at altitude.
- Fresh hot section done by Dynamic Aviation.
- S.T.C. allows Part 135 operation to 8,000 TBO under a Maintenance On Reliable Engines (MORE) program. Dynamic Aviation operates over 70 engines on King Airs to 12,000 TBO.
- Pedigree. Detailed parts and service history. All engines have complete log books and records on life limited parts including CT and PT discs, three compressor discs and centrifugal compressor.
- Due to the popularity of these engines, both parts and technical support are widely available. Dynamic Aviation has a huge inventory of parts and accessories in stock!
- Last OH or major repair was performed by the factory, Airwork, or Aviall/Dallas Airmotive.
- Airwork, Aviall/Dallas Airmotive enines were overhauled per the PWC Factory PT6A-20 Overhaul Manual and specifications. These shops are PWC approved and FAA repair stations.
- Engines have been stored in steel pressurized containers (not included in sale).
- Parts used while on the BASI contract were required to be OEM supplied.
- Compliance with all ADs.
- Compliance with a PT6A-20 internal part number conformity inspection.
