Osceola Mills, Pa.-based Innodyn will be showing off its latest turboprop engine–the TwinPack–later this month at EAA AirVenture in Oshkosh, Wis. Over the past several years the company has been quietly working on fuel-efficient, low-cost 200- to 300-shp turboprop aircraft powerplants with 5,000-hour TBOs. Building on this work, Innodyn has developed the 500-shp TwinPack, which combines two of its 250-shp turbines through a common gearbox.

Of some 3,572 TFE731-2 and -3 engines on U.S.-registered business jets that would have to get their low-pressure turbine stage 1 disks repetitively checked for fatigue cracks, it is estimated that about 1,900 would need to replace the disks, if the FAA adopts a proposed AD. The directive would essentially mandate compliance with a two-year-old Honeywell Service Bulletin that addresses possible fatigue cracking in the disks.
