While ongoing problems with the Safran Silvercrest have stalled the Cessna Citation Hemisphere’s development, the engine program is progressing toward testing a new axial high-pressure compressor in June 2019, which is hoped will meet the Hemisphere’s performance requirements.

Performance issues with the 12,000-lb.-thrust-class Silvercrest, Safran’s first purpose-built business jet engine, caused Dassault to cancel the Falcon 5X program late last year and Textron to suspend Hemisphere development in April.

Dassault then launched the Falcon 6X with a slightly larger fuselage and Pratt & Whitney Canada engines. Textron Aviation officials have said that without the Silvercrest engine, there will be no Hemisphere.

Assembly of the first compressor is planned for early 2019.
