Customers who bring their Cessna Citation to Sierra Industries of Uvalde, Texas, for major maintenance or inspection events can now drop off their jet and fly home in a loaner airplane. Under Sierra’s Fly-Thru maintenance program, Citation operators will be supplied an equivalent airplane or Sierra’s Williams International-powered FJ44 Citation, providing an opportunity to see how the modified version flies. The mods are available for the Citation 500/501 and 550 series. With FJ44-2A engines, the Citation 500/501 delivers 25 percent better fuel efficiency. The FJ44-3A conversion on the Citation 550 adds 400 nm of range and improves speed, climb performance, max-fuel payload and fuel efficiency. Sierra also announced a program to help customers upgrade to a new 406-MHz emergency locator transmitter (ELT). Although the FAA does not require the new ELTs, 121.5-MHz ELTs are no longer being monitored by global satellite systems. Sierra is offering a free 406-MHz ELT upgrade for customers who book a Phase 1 through 5 inspection.
