Sierra Industries sets new delivery records

Sierra
Industries have delivered three major Citation modifications to customers in
June 2012. These included another S550 model in Sierra’s fleet of Williams FJ44
powered Citations, the fourth installation of the recently STC for
Sierra/Garmin G501SP glass panel retrofit, and a Canadian Citation V fitted
with the 36″ Sierra cargo door modification.

The S550-based Sierra Super SII delivery marks aircraft number 59 in the
company’s FJ44 re-engining programme and the 12th aircraft to be retrofitted
with Williams International FJ44-3A engines.

The Super SII modification provides
substantial across-the-board performance improvement for the Citation SII –
enhancing fuel efficiency and reducing emissions by as much as 27%, boosting
cruise speeds by 30 to 40 knots, extending range to over 2,300 NM, and
increasing maximum fuel payload. Dual Channel FADEC controls provide smooth,
vibration-free flight for passengers and a reduced workload for the pilot.

June also marked the completion of their fourth G501SP “glass panel” retrofit for the
Citation 501. Two more Citation aircraft are currently undergoing G501SP installation
at the Uvalde facility. The system is applicable to all Cessna Citation 501
aircraft with either Pratt & Whitney JT15-D or Williams FJ44-2A engines.

The company also completed in June a Sierra Wide Door modification on a Citation
560 aircraft for a Canadian air ambulance operator. The Wide Door modification
opens up access to the Citation cabin for medical transport, cargo, remote
sensing and other specialised missions. The side-opening 36″ door utilizes
standard hinge and latch components for easy field maintenance.

The Sierra Wide Door modification is applicable to Citation 500, 501SP,
550, 551 and 560 models, the modification typically requires 10 to 12 weeks for
completion.
