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.
The EASA’s flat fee for a type certificate for a fixed-wing aircraft with an mtow of between 5.7 and 22 metric tons (encompassing the Cessna Citation CJ3 to the Falcon 900 series) is e1.06 million ($1.48 million). For a rotorcraft, it ranges from e20,000 to e525,000 ($28,000 to $735,000). Additional annual fees are levied to pay for the administration processes that ensure continued airworthiness.
Using serial-number-specific aircraft arrival and departure information on all IFR flights in the U.S. (including Alaska and Hawaii), data provider ARG/US concludes that business aircraft activity was down by 42.5 percent in January this year compared with the same month in 2008. That is the combined figure for all airplane categories and types of operation.
Two new notams affecting U.S. entry and overflight requirements went into effect last month. Notam 8/3576 covers U.S.-registered aircraft with an mtow of 100,309 pounds or less. These aircraft will not require an airspace waiver, as long as all applicable conditions outlined in the notam are met.
