Sierra Industries to develop “Sapphire” upgrade program for Cessna CitationJet, CJ1 and CJ1+ business jets

Sierra Industries engages with GE Honda Aero Engines to develop a new Citation Jet engine retrofit program

GREENBRIER, WV – September 18, 2014 – Sierra Industries, Ltd., announced at the 2014 Citation Jet Pilots Conference today a joint project to develop an engine retrofit program for the legacy Citation Jet platform using the recently certified GE Honda HF120 engine.

This new project, known as the Sapphire program, replaces the original factory-installed Williams FJ44-1A engines with the state-of-the-art GE Honda HF120 engine. The HF120 engine will provide the Citation Jet with improved performance and enhanced productivity. The Sapphire retrofit plan would include FADEC engine management along with redesigned engine pylons and nacelles for improved aerodynamics.

The Sapphire program targets all 525 series Cessna business jets, including all CitationJet, CJ1 and CJ1+ models. In addition to the HF120 engine change, a number of other upgrades are planned to be included in the modification package; including a gross weight increase, aerodynamic enhancements, and avionics and interior upgrades.

Sapphire will incorporate new technology avionics systems to integrate the airframe and engine modifications. The avionics integration, likely based on the Bendix King AeroVue™ platform, will provide the Citation Jet with state-of-the-art flight deck displays, integrating critical health parameters for the new engine. Derived from industry leading Honeywell avionics systems used worldwide on large and midsize business jets and air transport aircraft, the AeroVue™ Integrated Flight Deck offers a sophisticated avionics platform including industry-leading Flight Management System, Autopilot, SmartView™ Synthetic Vision, and INAV™ functionality with electronic charts displayed on three large LCD screens. Also included is a robust inflight Internet solution, the BendixKing AeroWave™ 100.

Mark Huffstutler, founder and CEO of the SkyWay Group remarks, “The 525 Citation Jet is an ideal match for GE Honda’s 21 st century HF120 engine. With the exhilarating performance that comes with a substantial power increase, owners of the Citation Jet would be able to consider a compelling choice when it is time to overhaul their engines or upgrade to a new aircraft.”

Over the past 20+ years, Sierra industries has successfully completed engine STC programs for numerous legacy jets, including the Citation 500, 501SP, 550 and S550 models and more recently the Hawker Beechcraft 400A and 800A series. Engineering for the program is spearheaded by sister company Skyway Aerospace Technology, Inc., while Sierra Industries provides component fabrication, engine and avionics installation and overall sales and support.
