Sierra chooses Williams FJ44-3 to modernize Citation II October 16th, 2006

The Williams FJ44-3 engine has been selected by Sierra Industries to improve the performance and reduce the operating cost of the Citation II

Orlando, FL 16 October 2006 – Williams International has been selected as the engine supplier for Sierra Industries’ supplemental type certification of the Citation II. Sierra was recently awarded an STC for its Stallion – the Citation I re-engined with Williams FJ44-2 engines – and now Sierra has launched a program to re-engine the Citation II with Williams FJ44-3 engine.

“We saw such great results on the Stallion,” said Mark Hufstutler, president of Sierra Industries, “that we’re very excited about the re-engined Citation II. Performance will go way up, operating cost and noise will go way down, and the FADEC controls will make the airplane easier to fly.”

The FJ44-3 engine currently powers the Cessna CJ3 and Grob SPn, and the Citation II will be one of its first retrofit applications. “We felt sure that once a 3000-pound thrust FJ44 was certified and in production, the retrofit market would embrace it,” said Matt Huff, vice president of Business Development for Williams, “and that’s what we’re seeing. Cessna built more than 800 Citation IIs in the 1980s, and these excellent airframes are ideal candidates for modern, efficient, quiet turbofans to extend their operating lives.”

FJ44 engines are renowned for their high performance and rugged reliability. They boast many advanced features pioneered by Williams and now being adopted by others in the small turbine industry such as blisks (integral blades and disks), effusion-cooled combustors, low parts count, and full authority digital engine controls (FADEC). They are also modular in design, allowing quick assembly, disassembly, and maintenance. Williams’ highly acclaimed Total Assurance Program will be offered for the FJ44-3 engines installed in the Citation II.
