The H80 was launched in 2009 based on the M601. GE added a new compressor, blisks, blades and new stators to enhance power by 3% and boost efficiency by 10%.[1] It reaches 597 kW (801 hp) (
The H80 was certificated by EASA at 13 December 2011, followed by the FAA at 13 March 2012.[3] Its Russian type certificate was received in October 2012, and the engine also approved by Brazilian Civil Aviation agency (ANAC) and the Argentine Administración Nacional de Aviación Civil.[4]
