This month UTC Aerospace Systems will complete deliveries of new brakes and wheels for the U.S. Air Force’s entire Lockheed Martin C-130 Hercules fleet. The brakes replace the original equipment, offering significant performance improvements, enhanced maintainability and reduced life-cycle costs. Compared to the original steel brakes, the new brakes cool much quicker, resulting in reduced time on the ground in “hot” landing zones.
Have any questions about your landing gear, brakes or other hydraulic systems on your aircraft? Stop by Tactair Fluid Controls at Booth No. N3217 to view a complete landing gear extension/retraction system, nosewheel steering system and helicopter wheel and brake system.
The engineering team at Gap-Tallard, France-based Beringer Wheels & Brakes has devised a new tailwheel design to help prevent ground loops in tailwheel-equipped airplanes. The patented “tailwheel with double pivot” essentially is a lockable tailwheel that is steerable while in the locked position. Beringer also announced that it has received a supplemental type certificate for a complete Cirrus SR20/22 replacement wheel and brake system with Beringer’s anti-lock inline regulator (ALIR) anti-skid braking feature.
UTC Aerospace Systems (Chalet A330, Hall Concorde 35) has won a contract from Virgin Atlantic Airways to supply the wheels, carbon brakes and MRO services for the airline’s fleet of 16 Boeing 787-9s, the first of which the airframer plans to deliver in September 2014. UTC Aerospace said it would supply the parts through its Wheels & Brakes division, based in Troy, Ohio.
The carbon brakes on the 787-9 use UTC’s Duracarb carbon heat sink material, which, according the company, lasts 35 percent longer than competitive products.
Eclipse Aerospace is offering an anti-skid braking system for new and existing Eclipse 500/550s. The lack of anti-skid braking has proved a problem for the airplane, with locked brakes contributing to several blown-tire incidents. The system, which adds approximately 17 pounds to aircraft empty weight, includes brake control and wheel speed sensors, a dedicated control computer and software updates to the avionics. Testing has indicated it is possible to stop the aircraft from normal landing speeds in less than 750 feet using “aggressive” braking.
Eclipse Aerospace announced last week that an anti-skid braking system will become an available option on new production Eclipse 550 jets as a retrofit item to all existing aircraft. The new anti-skid system adds 17 pounds to the aircraft’s empty weight; the company says it will offer a weight-reduction package to help offset the new feature.
Eclipse Aerospace has added an anti-skid braking system as an option for its new-production Eclipse 550s, and it plans to offer it as a retrofit for in-service Eclipse 500s early next year. Eclipse says that in-aircraft testing of the anti-skid braking system is complete and that it expects to begin delivering certified systems by late March. Performance demonstrated during testing has prompted Eclipse to seek to adjust the aircraft flight manual performance numbers for Eclipse 500s and 550s with the improved braking system.
Messier-Bugatti-Dowty will be Eurocopter’s single-source supplier for wheels and brakes on the new X4 medium-twin helicopter. The Safran company will provide the two nosewheels, two main wheels and two electric brakes, the electronic brake controller and four brake pedal transmitter units. Messier-Bugatti-Dowty’s electric brakes are designed “to reduce weight, while retaining excellent friction properties” and simplifying maintenance.
The FAA is proposing to rescind an Airworthiness Directive (AD 200-07-11) issued for all Piaggio Avantis to prevent the brake hydraulic fluid from leaking. It was prompted by reports of brake assembly rods contacting the brake valve tubing, which could compromise the airplane’s ability to stop during ground operations. Since then the FAA has determined it is no longer an unsafe condition and that regularly scheduled annual inspections address the subject. The FAA is taking comments until September 4.
Goodrich has been awarded a contract extension to continue to maintain and overhaul the wheels and brakes of easyJet’s Airbus A320-family fleet. Meanwhile, the U.S. equipment manufacturer also revealed that it has demonstrated the performance of its carbon brakes on U.S. Air Force’s C-130s, for which retrofits have already started.
