The engine was originally designated the AS907, which was changed in 2004 to HTF7000; the AS907 designation is still used for legal and regulatory use.[4]By October 2016, 2.6 million hours had been logged by 1,400 in service engines and it has a 99.9% dispatch reliability rate.
Average fuel consumption is about 950 lb. per hour for a 7,765 lbf engine on a G280, to be compared to 875 lb. per hour for a 4,420 lbf TFE731 on a G150.[3]More than 3.5 million flight hours have been logged till October 2017, and the 2,000th engine should be delivered in 2018.[2]
Higher thrust variant of the AS907, designed at the same time, intended to power BAE System's Avro RJX.[8] The aircraft was cancelled after three airframes were built and flown; subsequently this variant never entered production.
HTF7250G / AS907-2-1G[7]
7,624 lbf (33.91 kN) variant developed for use on the Gulfstream G280.[9]
