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.
