After four years of development and almost 500 hours of flight testing, the Raisbeck ZR Lite System for the Learjet 35/36 has earned an STC.
An STC for after-production installation of the auxiliary fuel tanks for the Boeing Business Jet 2 is expected this month, about three months later than originally planned. PATS of Columbia, Md., is doing the aux tank installation in addition to BBJ2 winglet installations at its Georgetown, Del. facility.
Aviation Partners expects to obtain an STC early this month on its blended winglets for the Hawker 800 series. The project has been in the works for a couple of years. “Manufacturing problems,” failure to obtain certain OEM data and changes in FAA certification methods lengthened the STC process.
Aviation Partners said 30 hr of initial flight testing of its winglets installed on a Hawker 800 (designated the 800SP) has verified a 7-percent reduction in cruise fuel consumption, netting an increase of 150 to 200 nm in range, “significant” improvement in takeoff second segment climb, better payload capability from hot-and-high airports and optimum cruise altitudes of about 2,000 ft higher.
Bombardier has selected Dubai as the venue for the airshow introduction of the Learjet NXT, an all-new business jet intended to fill the market gap between the company’s $13.3 million Learjet 60XR and $21 million Challenger 300.
“Welcome to Lear Jet Country,” a marketing slogan that attached itself to the early-20-series Lear Jet, is likely to be remembered only by industry old-timers who recall the airplane’s ability to take off and climb to 41,000 feet without effort. It is a capability that disappeared with the advent of the Learjet 35/36.
The first test flights of a Cessna Citation X equipped with Winglet Technology’s new elliptical winglets are proceeding well, according to Bob Kiser, president of the Wichita-based modification kit manufacturer. The winglets are expected to give the airplane an even higher maximum cruise speed at high altitude as well as improved climb performance and longer range.
Aviation Partners said it is in the “preliminary stages” of “looking at the entire Citation line” as the possible next candidate for the company’s performance-enhancing blended winglets. No timetable, however, was immediately available. Meanwhile, the Seattle-based company expects to receive certification of its blended winglets for the Hawker 800 and 800XP in mid- to late summer, more than a year later than originally planned.
Attempting to jump on the homeland-defense bandwagon, Aviation Technology Group at Denver Centennial Airport proposed earlier this year that its twin-engine, tandem two-seat “personal jet” could indeed perform military service as a subsonic (Mach 0.92) interceptor.
Aviation Partners now expects to obtain an STC this month for its winglets for the Hawker 800 series. The project has been in the works for a couple of years. Failure to obtain certain OEM data and changes in FAA certification methods lengthened the STC process. According to CEO Joe Clark, “We recently started getting more assistance from Raytheon Aircraft.” Clark said a Hawker 800 with winglets will be on display at the NBAA Convention.
