Clifford Development appointed Little Rock, Ark.-based Central Flying Service as a service center for the Company’s Citation II and Citation S/II re-engining programs. Both programs use Williams International FJ44-3A engines. Two parallel supplemental type certificate programs are under way at Clifford Development to re-engine the Citation II and the Citation S/II.

The Citation II certification airplane is currently undergoing flight tests in Mojave, Calif., with FAA flight tests slated to conclude shortly. Initial flight test results for the Citation II support the original performance estimates for the Williams engine conversion, including a long-range cruise speed increase (21 percent) and an NBAA IFR range improvement (29 percent).

The Citation S/II certification airplane is currently being modified with the Williams International FJ44-3A engines. An abbreviated flight-test program is scheduled for early this year, with approval for both STCs anticipated sometime in the first half of this year.

The Citation II and S/II engine conversions are priced at $2.150 million and $2.275 million for 2008 installations. The price includes a credit for the original engines.

Central Flying Service will provide complete sales, installation and service support for Citation II and S/II owners who purchase the Clifford engine STC. Service centers receive technical support and complete installation kits from Clifford Development. Installation time for new engines is estimated to be about six weeks.
