Sierra Stallion Receives FAA Approval

With the June 14th first flight only nine weeks old, Sierra has received its Supplemental Type Certificate (STC) for the Stallion. A Cessna Citation 500 / 501SP with the more powerful Williams FJ44-2A engines, the Stallion is the latest in Sierra’s Citation product improvement program. Preceded by innovations such as the Eagle II, the Eagle 400 and Eagle SP, the Stallion enjoys the added power of the FJ44 engine, but retains the thinner, classic wing of the Citation I.

Mark Huffstutler, CEO of Sierra says, “The Stallion offers the exhilarating performance that comes with a substantial power increase and provides owners with choice when it is time to overhaul engines. We climb the Stallion straight to FL430 at any weight or temperature and cruise 380 knots on 620 pounds per hour for more than 1400 miles. Where else can you get this combination of performance for the price?”

“Another very notable feature of this program is that the electronic engine controls virtually eliminate any engine management issues. These controls automatically determine the proper power setting from the conditions present and set the maximum power for that condition – push the throttles to the stop for takeoff and never touch them again until descent. There is also a considerable difference in the sound and vibration of the Williams engines which is apparent once you start the engines. They are extremely smooth and in flight the engine noise and vibration are noticeably less making for a much quieter and more comfortable cabin”, said Huffstutler.

Like the Eagle II, the Stallion climbs directly to 43,000 ft and accelerates to a high Mach number. With the enhanced fuel specifics, the Stallion is the perfect aircraft for intermediate-length trips carrying a crew and six passengers to and from airports that demand high performance.

Sierra can convert a customer’s Citation 500 or 501SP to a Stallion with a lower investment in time and money than an Eagle II, and still retain the capability of returning at a later date for the Eagle II if more range is desired.
