New designs for small business turboprop singles could be included in proposed changes to FAR Part 36 noise-certification rules. The more stringent levels are aimed primarily at reducing noise from newly designed primary training aircraft, but new turboprop singles certified under Part 23 would also be covered. The FAA said the more stringent requirements are intended to keep limits within the capability of current technology.
Maximum Takeoff Weight
Because the Grob SPn Utility jet and the Embraer Phenom 300 weigh more than 12,500 pounds but less than 19,000 pounds, their respective manufacturers are requesting permission to certify the aircraft under the commuter category of Part 23 rather than the more stringent requirements of Part 25.
Mojave, Calif.-based Scaled Composites recently modified the Virgin Atlantic-sponsored GlobalFlyer with fuel jettison capability at the request of pilot Steve Fossett, who is scheduled to fly the single-engine Williams FJ44-powered aircraft solo around the world nonstop without refueling sometime after January 4.
Cessna anticipates that its Model 680 Citation Sovereign super-midsize business jet will receive full type certification before the end of next month. On Christmas Eve the new aircraft received provisional certification, with flight into known icing the only major outstanding approval still pending. Cessna reports orders for about 100 aircraft.
All subsonic jet and transport-category airplanes (those with an mtow of 12,500 pounds or more) for which application of a new type design is submitted on or after Jan. 1, 2006, will have to meet new noise certification levels, under a long-expected notice of proposed rule making (NPRM) published December 1.
The pilot flying a Cessna Caravan that crashed after takeoff on Oct. 6, 2005, in Winnipeg, Manitoba, violated operational requirements, according to the Canadian Transportation Safety Board’s final report. Among the violations were taking off at a weight greater than the legal maximum takeoff weight and exceeding the time allowed between wing contamination inspection and takeoff.
All jet and transport-category airplanes (those with an mtow of 12,500 pounds or more) for which application of a new type design is submitted on or after January 1 this year have to meet new noise certification levels. Stage 4 is a cumulative 10 EPNdB (effective perceived noise level in decibels) less than Stage 3 limits. Virtually all in-production business jets will qualify to be recertified under Stage 4.
It was no big secret before this year’s NBAA Convention that Piper would be announcing plans for a single-engine jet, and indeed Piper did unveil its PiperJet on October 17. At the time, Piper had not yet selected an engine manufacturer. Early last month at the AOPA Expo in Palm Springs, Calif., Piper revealed that a Williams International FJ44-3AP will power the PiperJet.
After operating below the radar for several years, Maverick Jets, now headquartered in Jackson, Wyo., revealed it is working on a next-generation Maverick Leader called the SmartJet. The five-seat, twin-turbofan, all-composite SmartJet has a planned mtow of 4,160 pounds, an empty weight of 2,150 pounds, a normal cruise speed of 277 knots at 22,000 feet and a max range of 1,250 nm.
The first Dassault Falcon 7X is earmarked for delivery to the French group’s patriach Serge Dassault at the beginning of April 2007 in time for his 82nd birthday. The French senator will take delivery of the first of the “more than 85” trijets currently on order–not on behalf of Dassault Aviation, the group of which he is the main shareholder–but as a private customer.
