Wing-tip extensions–known as winglets–that reduce aerodynamic drag and improve fuel efficiency and range have become familiar features on a variety of business and commercial jets. Quiet Wing Technologies (Booth No. C10432), Redmond, Wash., says it was the first company to certify winglets on a transport category aircraft–the venerable Boeing 727, many of which are still in operation as VIP-configured aircraft.

The 14th anniversary of TWA 800 came and went this past July 17. Except for family members of the victims, few remember anniversaries of tragedies after the 10th year has passed. The media and general public might lose interest, but for those working to prevent a future disaster, the memory of the Boeing 747 midair explosion remains vivid and concerns about preventing a similar future disaster remain strong.
Cessna Citation 680, Bedfordshire, UK, Sept. 30, 2010–While en route from London Luton Airport to Milas, Turkey, the Sovereign suffered a left main bus electrical system fault that prompted the crew to return to Luton.

US Aviation in Denton, Texas, is the first FBO in the U.S. to install stainless steel-lined fuel tanks in its fuel farm. Traditional fuel storage tanks use an epoxy inner liner, and this liner “has a tendency to break down,” according to Jeff Soules, the FBO’s senior v-p and general manager. Benefits of the stainless-steel liners include no initial startup problems or chips, flaking or biological disintegration of the epoxy, he said.
British safety officials have issued recommendations for flight-data recorders (FDRs) to record engine fuel-metering information and for reviews of landing-gear failure requirements and Boeing 777 data buffering. Accident investigators call for the action among nine safety recommendations in the final report of the Jan. 17, 2008, British Airways Boeing 777-236ER accident at London Heathrow Airport, which was released on Tuesday.
Jet Aviation, one of only two authorized Pats Aircraft Systems modification specialists for auxiliary fuel tank maintenance, is performing the mod work at its Basel and Geneva maintenance centers in compliance with the latest amendment to Special Federal Aviation Regulation 88 (SFAR 88).
Parker Hannifin’s Parker Aerospace division is exhibiting new fuel tank and engine nozzle technologies at this year’s NBAA show, as well as flight control, hydraulic, water and waste-system components that it manufactures for a variety of OEMs. Parker’s fuel-filtration and water-coalescing system eliminates water as it is uploaded in the fuel tanks, uniting the water molecules and removing them.
Jetaire Aerospace of Fayetteville, Ga., says it has exceeded the compliance requirements for the SFAR (special FAR) 88 FAA Airworthiness Directive for explosion-suppressant systems for auxiliary fuel tanks.

Parker Hannifin has signed two agreements with major aerospace companies, which could net the company some $7.5 billion over the life of the programs. It will be partnering with Rolls-Royce on the Trent XWB engine for the new Airbus A350XWB family of airliners. Parker will provide the complete hydraulic and fuel systems for the A350XWB, as well as the fuel tank inerting system.
