The US Federal Aviation Administration has awarded Soloy a supplementary type certificate (STC) for its 1,330shp (1,000kW) Dual Pac, which uses two Pratt & Whitney Canada PT6 engines to drive a single propeller. A special condition specifies that the powerplant should continue to run if one side loses power, which Soloy has covered by incorporating dual-redundant load paths to the propeller. First application will be on the Soloy Pathfinder 21, a re-engined Cessna 208B Caravan, which is due to be certificated by the end of 1998.
