The Cessna Citation CJ4 gained FAA type certification last month, with deliveries of the light jet set to begin later this year. The final performance numbers for the $9 million CJ4 include a takeoff distance of 3,130 feet at mtow, a maximum speed of 453 knots and 2,002-nm range with two crew and five pax.

Final agreement over the way the European Union’s new “common basic standards for aviation security” are implemented in the UK will not be achieved by the existing April 29 deadline and could well be delayed at least until late June due to the country’s general election, which is widely expected to be held on May 6.
Aviation Research Group/US (ARG/US) is endorsing the International Standard for Business Aircraft Operations (IS-BAO) as the “one standard that all operators of business jets around the world would be measured by and audited against.” According to ARG/US CEO Joe Moeggenberg, if the industry does not take this opportunity to make IS-BAO– along with its safety management system (SMS) component–the world standard, then each governmental aviation
Blackhawk Modifications (Booth No. 2935) has received supplemental type certificate (STC) approval of its XP28 upgrade for the Piper Cheyenne I with Pratt & Whitney Canada PT6A-28 engines in place of the original PT6A-11s. The new engines will allow power to be carried to a much higher altitude and increase speed to 250 ktas.
The FAA has issued a notice of proposed rulemaking (NPRM) that will attempt to close some loopholes in the Part 23 regulations under which light jets and other airplanes are certified. The NPRM is open for comments until November 16, and the easiest way to view the proposal is to search the term “Docket No. FAA–2009–0738” at www.regulations.gov.
GP Aerospace, a Brazilian startup company established by former Embraer technical director Guido Pessotti, has revealed to AIN plans for a personal very light jet, which would be smaller than currently available very light jets.
The Airbus Corporate Jetliner (ACJ) received EASA approval for a new mtow of 76.5 metric tons (168,700 pounds), one metric ton more than was previously available. The higher limit extends the ACJ’s range with eight passengers to 6,000 nm, an increase of 170 nm over the standard version. The mtow increase is made possible by a new
The FAA has issued a number of special conditions needed for Spectrum Aeronautical’s all-composite S.40 Freedom twinjet to achieve type certification. The issuance of special conditions is nothing unusual in any certification program. The regulations do not cover every design eventuality, and some special conditions are needed.
French startup company Price Induction is studying an engine with a two-stage contra-rotating fan as a way to reduce fuel burn on very light jets. The Taor 380-1 would have a thrust of 720 pounds and cut fuel burn by 20 percent, compared with the company’s DGen 380 conventional turbofan engine. The latter claims a specific fuel consumption of 0.715. The Taor 380-1 would be suited to 4,400-pound-mtow aircraft, enabling speeds of 250 knots.
Spectrum Aeronautical’s all-composite S.40 Freedom light jet is subject to a number of special conditions mandated by the FAA to achieve type certification. These conditions cover many flight and performance characteristics, as well as new requirements for lithium main, auxiliary and emergency batteries.
