Canada’s National Research Council (NRC) achieved a milestone in the quest for adoption of biofuels when it made the first flight by a civil jet powered by 100-percent unblended biofuel. At the end of October, the NRC’s Dassault Falcon 20 made the historic flight over Ottawa, burning a new biofuel known as ReadiJet, derived from Brassica carinata, an inedible oilseed crop provided by feedstock producer Agrisoma Biosciences.
Centurion Aircraft Engines’ Centurion 2.0s is now available in Europe as an upgrade through a supplemental type certificate (STC), which covers installing the 155-hp engine on the Cessna 172F through -S models. EASA issued the STC to Centurion on May 21. The 2.0s provides 20 more horsepower than the original Centurion 2.0. It is Fadec-controlled to keep engine parameters within range and is operated through a single lever power control.
Costa Rican regional airline NatureAir has entered talks with the government of the Central American republic for permission to sell biodiesel fuel to other companies. Despite the fact that its fleet of six de Havilland Canada Twin Otter turboprops runs on jet-A, serving 17 destinations in Costa Rica and Panama, NatureAir calls itself the world’s first carbon-neutral airline.
The diesel-powered Diamond DA42 TwinStar made its first flight on December 9 from the factory at Wiener Neustadt, Austria. TwinStar’s Thielert Centurion 1.7 engines rated at 135 hp each are designed to operate on both diesel fuel and jet-A1. The composite-construction four-seat aircraft has a single-lever power control for each engine, fuel consumption of 67 pph at 180 kt and an option for an all-glass cockpit.
Green Flight International last month conducted the first flight of a jet using 100-percent biodiesel fuel. The experimental test flight was flown by an L-29, a military aircraft that is rated to fly on a variety of fuels, including heating oil, making it a “preferred platform” for testing biodiesel in jet engines.
A provision in the legislation to reauthorize the nation’s surface transportation programs, known as the Highway Bill, would “drastically alter the way the taxes on jet fuel are collected,” according to the National Air Transportation Association. Under the proposal, jet fuel would be taxed at the same 24.4-cent-per-gallon rate as diesel fuel.
Business aviation lobbyists yesterday applauded recent action taken by Republican lawmakers to shelve new tax rules in the 2005 Highway Bill designed to discourage truckers from using jet fuel to avoid higher taxes on diesel fuel. At the request of NBAA, NATA and GAMA, Sen. Ted Stevens (R-Ark.), Sen. Conrad Burns (R-Mont.) and Rep. Robin Hayes (R-N.C.) sent letters to U.S.
Republican lawmakers have taken steps to shelve new tax rules in the 2005 Highway Bill designed to discourage truckers from using jet fuel to avoid higher taxes on diesel fuel. Sens. Ted Stevens (R-Alaska) and Conrad Burns (R-Mont.) and Rep. Robin Hayes (R-N.C.) sent letters to U.S.
If the provision is accepted by the House and the bill signed by the President, all aviation fuel will be taxed at the same rate as highway diesel fuel–24.4 cents per gallon. The purchaser would then have to submit a claim to the Internal Revenue Service to receive the difference between the 24.4 cents paid and the 21.8 cents per gallon actually owed.
