GE seeks EASA approval of S10 diesel fuel for H Series turboprop

GE Aviation submitted an application to EASA to utilize S10 diesel fuel for its H Series turboprops. The anticipated application approval would help Brazilian H Series operators lower fuel costs by up to 25%. The average H Series engine consumes 648,000 liters of fuel before its first scheduled overhaul at 3,600 flight hours. By utilizing S10 diesel, operators could save more than $225,000 (US$) on fuel costs between overhauls. The H Series turboprop family – which includes the H75, H80 and H85 engines – incorporates GE’s 3-D aerodynamic design techniques and advanced materials to create a powerful, fuel-efficient, durable engine with no recurrent fuel nozzle inspections and no hot section inspection. On the H Series, GE is also developing an integrated electronic engine control (EEC) for true single lever power control, and full auto-start capability to help ease pilot workload. GE’s H Series powers nine applications including the Thrush 510G, Nextant Aerospace G90XT and Aircraft Industries L410 aircraft. The engine family provides the option of a single- or dual-acting governor, allowing customers to have flexibility in propeller selection. The engine is targeted at the agricultural, business turboprop, commuter and utility aircraft segments.
