That makes two manufacturers who have backed out of using the Safran Silvercrest due to its performance issues.
[/Hemisphere could be revived at a later date, Donnelly acknowledged, but for now it’s “on hold” because the Wichita-based manufacturer isn’t satisfied with progress on the development of the Safran Silvercrest engine that would power it.
Further, Safran said its initial contract with Textron Aviation for the Silvercrest has been terminated with no financial impact to either company. The troubled engine program, which caused French airframer Dassault to cancel the Falcon 5X in late 2017, has made progress on fixing the engine’s high-pressure compressor but so far is falling short of what Textron needs.
“The engine hasn’t yet demonstrated the performance required for the aircraft,” Donnelly explained. “We would certainly revisit it [Hemisphere], but too much time has gone by here.”
My understanding is it is not just the high pressure compressor that is causing the performance issues. Its just not meeting any of the targets spelled out. Apparently enough to allow breaking the contract without any financial penalties.
Cessna already has its plate full with multiple programs at this point. Makes you wonder what their long term position with the Hemisphere is given they already have 150 options on the book with Netjets.
What options are available to replace the silvercrest engine? Any existing engines that can fit that role?
