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.

Securaplane Technologies of Tucson, Ariz., has announced the availability of a sealed lead-acid battery for Gulfstream IIIs and IVs and Falcon 2000/2000EXs. The EnerSys Hawker battery is a direct replacement for the Ni-Cad battery and does not require any modification to the existing charger or battery-temperature system on the aircraft.

As every pilot and mechanic knows, high temperatures are the bane of any engine. But as engineers strive to design smaller, more powerful turbine engines by adding compressor stages, the compression ratio goes up and so does the temperature of the ram air. At a compression ratio of about 20 to 25, ram-air cooling becomes inefficient. The solution, researchers believe, lies with cooling the air before it goes into the combustor.

At General Electric, the official corporate slogan is “Imagination at work.” At Honda, it’s “The power of dreams.” The two companies announced last month they have merged them in an alliance to develop, certify, market and support Honda’s 1,670-pound-thrust HF118 turbofan. The result could be one of the most innovative global alliances in business-aviation history.

Honeywell’s small heavy fuel engine (SHFE), in development since 2003, “will change the game for turboshaft engines in the future,” predicted Ron Rich, the company’s director of advanced aerospace technology.

Pilatus PC-12, South Bend, Ind., Dec. 14, 2004–The NTSB blamed the crash of PC-12 N922RG on the failure of the fuel control unit bellows, which resulted in a significant loss of engine power. The pilot made a forced landing on a roadway after, he said, the engine “abruptly and smoothly rolled back” shortly after takeoff from South Bend Regional Airport. The airplane’s wingtip hit two utility poles during rollout.

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.

One of the technologies that Honeywell says promises to revolutionize aircraft design is something known as “more electric architecture” (MEA). This “breakthrough” technology will replace much of today’s heavy and maintenance-intensive pneumatic and hydraulic fluid and power systems, enabling OEMs to design aircraft with lighter, simpler and more reliable “electric” systems instead of miles of tubing, pumps and valves.

Bell 407, Broadus, Texas, March 27, 2003–The NTSB said the probable cause of the 407 crash was “the partial loss of engine power due to erratic fuel flow metering to the engine resulting from the single-point failure of the PLA potentiometer in the hydro-mechanical fuel control unit.” A contributing factor was the lack of suitable terrain for a forced landing.
