A UK-based company called Project 1221 is developing a limited-run, high-end sports car powered by a 1,500-shp variant of the Williams International FJ44 engine. The $816,000 (E675,000) jet-powered car will come in two versions–the three-seat MF1 treposti or two-seat MF1 dueposti. Both models are available in an all-wheel- or rear-wheel-drive configuration, and the steering wheel can be installed on the left- or right-hand side.
Spirit Wing Aviation of Edmund, Okla., said it now expects to receive STC approval for its $2.2 million SpiritLear–a re-engined Learjet 25–in the first quarter of next year. Last year, the company expected certification this past summer.
Citation modification specialist Sierra Industries of Uvalde, Texas, last month received an STC for its Stallion conversion, a Citation 500/501 powered by Williams FJ44-2A turbofans in place of the twinjet’s original Pratt & Whitney Canada JT15Ds.
The Grob SPn Utility Jet’s flight-test program has been progressing well since the twinjet made its first flight last July 20, according to a company spokesman. As of early last month, German-based Grob had already verified the twinjet’s flight characteristics throughout the full c.g. envelope.
Expect Cessna at the NBAA Convention next month to announce the Citation CJ4, a stretched version of the CJ3 with a slightly swept wing based on the Sovereign airfoil. The new aircraft, with a cabin 21 inches longer than the CJ3, will be powered by 3,400-pound-thrust Williams International FJ44-4 turbofans and will likely replace the Encore.
