The Learjet Model 60 is the subject of a recent FAA Safety Alert for Operators (Safo) to maintain the correct tire pressures. FAA Flight Standards Service Safo 09012 recommends measuring cold tire pressure at the intervals recommended by the manufacturer.
After issuing a proposed Airworthiness Directive that will require operators of Learjet 60s to revise flight and maintenance manual tire inflation information, the FAA has published a Safety Alerts for Operators (SAFO 09012) that addresses tire inflation on all aircraft.
Crane Aerospace & Electronics (Hall 5 Stand A24) is here at the show providing demonstrations of its SmartStem wireless tire pressure monitor, introduced two years ago on the Boeing 777. The technology replaces existing tire inflation valve stems with a special wireless tire pressure sensor valve that communicates tire pressure, temperature and other information to the cockpit or to a handheld reader.
One hundred years after introducing the first aviation tire–the Wing Aeroplane tire–Goodyear Tire and Rubber is adding a new tire to its lineup, the Flight Eagle LT designed for light jets, including very light jets and single-engine entry-level jets. The six-ply Flight Eagle LT is optimized for higher-speed applications with a reinforced bead area, high-speed tread compound and a two-groove tread design.
Crane Aerospace of Lynnwood, Wash., is developing an aircraft version of a handheld remote tire-pressure indicator that Goodyear developed for automobiles. SmartStem consists of a handheld digital readout device and a tiny, wireless pressure/temperature sensor embedded in the tire’s inflation valve or mounted on the wheels. The user aims the handheld unit at the sensor to obtain a readout of the air pressure, according to Crane.
The rejected takeoff of a Boeing 777 at approximately 160 knots results in the landing gear absorbing more than one billion joules of energy in a few seconds, according to research recently done by Messier-Bugatti. To put this number in perspective, consider it as the equivalent of supplying energy to the average house (lamps, outdoor lights, refrigerator, television, computer and other appliances) for about 18 hours.
Technology that can tell a farmer whether a cow has a fever is the basis for a new monitoring system for aircraft tires.
Boeing has awarded Goodyear Tire & Rubber, the world’s largest supplier of aircraft tires, a six-year contract to provide Flight Leader and Flight Radial tires for 737NG aircraft. The “unique body cord shape” of the reduced-weight units is said to minimize stress on takeoff and landing. The tires will equip aircraft to be delivered to operators such as All Nippon, Continental, Ryanair and Southwest.
Aircraft Spruce & Specialty of Corona, Calif., has entered an exclusive arrangement with Gentco to market that company’s new nitrogen tire inflation system.
Goodyear Tire and Rubber grabbed some traction in the aviation tire business with a series of contracts signed just before this year’s show. Most recently, it chose its second aviation tire evaluation center, the 43 Air School in Port Alfred, South Africa. Embry-Riddle Aeronautical University in Daytona Beach, Florida, serves as Goodyear’s other evaluation center.
