Company Has Modified More Than 70 Citations Overall

The latest Cessna Citation to receive Sierra’s FJ44 re-engining modification was recently delivered from Sierra’s South Texas modification facilities. Marking a significant milestone in their series of Citation engine upgrades, the newly delivered aircraft is the 50th Citation to receive the Williams International FJ44-2A engine retrofit. Including their previous Eagle 400 modifications and FJ44-3A upgrades for Citation II and SII models, Sierra has now performed engine retrofits to more than 70 Citation aircraft.

Stallion #50 owner Dr. Howard Tobin is reportedly delighted with his newly upgraded Citation. Dr. Tobin is a Director of the Citation Jet Pilots Association and, as moderator of the Legacy Aircraft Discussion Forum, has shared his re-engining experience in “real time” with the members of the organization.

“All I can say is WOW! ...this was one of the most exciting steps for me in my flying career. So far, all I can say is “why did I wait so long?,” he commented after flying the airplane. "At 41,000’, it sure was nice to be looking at 190 knots indicated (mach .65), compared to the old 153 (mach .58) and the climb was probably the biggest boost. Up to 41,000 feet with full fuel, 4 persons and quite a bit of baggage in about 30 minutes, still climbing 500 feet per minute. How I remember how we used to struggle above 35,000. While the conversion is great, I guess what I love the best is that I still have my faithful 41GT.”

Sierra’s FJ44-2A re-engining programs for Cessna Citation 500 and 501SP models include the Stallion and the Eagle II, which adds their classic Eagle wing/fuel tank upgrade to the engine retrofit. Citation II and SII owners can choose FJ44-3A based Super II and Super SII modifications. All of these modifications utilize state-of-the-art Williams International fanjet engines to provide dramatic improvements in power, efficiency and reliability.
