The first delivery of a Sierra Industries‘ Super II took place late last year.
The Sierra Super II modification upgrades the Citation II’s performance by re-powering the aircraft with Williams International’s FADEC-controlled 2,820-lb. thrust FJ44-3A engines.
Sierra Industries has received FAA certification to install the Williams engines on six different models of certificated aircraft, according to officials, who note the company has numerous FJ44-powered aircraft in current production at its facilities in Uvalde, Texas, with an order book stretching well into 2009.
The Super II provides an across-the-board performance enhancement for the Citation II – boosting fuel efficiency and reducing carbon emissions by as much as 27%, cutting time-to-climb to under 25 minutes to FL430, extending range to nearly 1,800 nm, and increasing maximum fuel payload, according to company officials.
