Stevens Aviation May Install Citation 550/S550 Engine Retrofits

Clifford Development announced this week the appointment of Stevens Aviation as an authorized installation center for the company’s certified installations of Williams FJ44-3A engines on the Cessna Citation 550 and the S550.

"We are very pleased to add the many services that Stevens Aviation has to offer," said Jim Clifford, chief executive officer of Clifford Development. "The company’s technical expertise, corporate jet maintenance experience and tradition of customer care will be important to our mutual customers. In addition, Stevens Aviation can provide virtually any airframe, interior or avionics service that our customers might require."

Clifford Development has certified 35 improvements as part of a recently issued Supplemental Type Certificate (STC), including: an Ametek digital engine display, heavy duty BFG brakes and a dual FADEC system certified to July 2007 standards. The Williams FJ44-3A is thermodynamically rated at 3000 lbs. (with takeoff flat-rated thrust of 2820 lbs.) versus the original engine's 2500 lbs. rating.

With this modification, the typical Citation 550/S550's basic operating weight is also reduced 250 lbs.

"Our customers have expressed a strong interest in this product," said Jim Williams, vice president of Stevens Aviation. "Our research indicates this product meets the demanding expectations of our customers."

Stevens Aviation becomes the fourth Clifford Development Service Center. Stevens will provide installations at its Greenville, SC (GYH) location and will provide additional product support at its Denver, CO (BJC) and Dayton, OH (DAY) locations.

The Citation 550 and S550 engine conversions are priced at $2,295,000 and $2,395,000 respectively for 2009 installations. This price includes engines, engine core credit, digital engine instrumentation, Clifford Development aircraft improvement package, installation labor and training.
