Re-Engining Mods Now Approved In More Than 33 Countries

Canada’s Department of Transport has amended STC approval number SA06-54 for Sierra Industries, adding the Citation 550 and S550 models to their existing Williams FJ44 engine upgrades for Cessna Citation 500 and 501 aircraft. Since the initial 2002 certification, Sierra’s FJ44 modifications have been applied to 54 aircraft. The high-performance fleet of Citation I, II and S-II aircraft have amassed a total of more than 50,000 hours of Williams engine operation to date.

Williams International’s 3rd-generation engine technology increases efficiency, reducing fuel burn, operating cost and carbon emissions. Since the 2002 introduction of the FJ44 Eagle II, Sierra’s FJ44 fleet has reduced worldwide carbon emissions by an estimated 10,000 tons. The aircraft also enjoy substantial performance improvements, ranging from 35 to 50 knot cruise speed increases and 300 to 400 NM greater range to dramatically improved climb performance. In fact, all 4 models can achieve FL430 at gross weight in under 25 minutes from any North American airport, making them ideal candidates for remote Canadian locations and high altitude airfields.

Building on Sierra’s 25 years of Citation modification history and 15 years of experience in Citation re-engining, Sierra’s current re-engining lineup includes the highly successful FAA and EASA-approved FJ44-2A Eagle II and Stallion and the FAA-approved FJ44-3A Super II and Super S-II modifications. Supporting these modifications with their extensive in-house manufacturing capabilities, Sierra is among the largest holders of FAA Parts Manufacturing Approvals (PMA) in the southwestern US.

Sierra recently announced new incentives for advance booking of 2010 modifications, reducing their 2009 pricing. FJ44-2A Stallion upgrades start at under $1.55 million and FJ44-3A Super II and Super S-II positions are available starting under $1.75 million. Trade-in allowances are also available on existing Pratt engines with time remaining.
