The FAA is proposing to issue an Airworthiness Directive requiring insertion of “revised procedures for servicing tires and checking for proper tire inflation” in Learjet 60/60XR maintenance and flight manuals.
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.
The UK Air Accidents Investigation Branch (AAIB) has issued four safety recommendations in response to an incident in which a burst tire on a Bombardier Global Express caused “extensive damage” to the flight control system.
Bombardier CL-600-2C10 CRJ, Denver, July 29, 2008–The Skywest flight blew the left main tires on departure, tearing off the gear door. No injuries were reported.
The NTSB said both main tires blew before the Learjet 60 (N999LJ) overran Runway 11 and crashed while taking off from Columbia (S.C.) Metropolitan Airport just before midnight on September 19. The two crewmembers and two passengers were killed; two other passengers suffered serious injuries and have recovered.
Recommendations for safely installing, inflating, inspecting, maintaining and removing aircraft tires are the subject of proposed advisory circular AC 20-97B. Comments on the new document must be received by the FAA before June 17. To see the proposed circular, go to www.faa.gov/avr/afs/acs/ac-idx.htm.
British Airways (BA) flew a modified Concorde to Shannon, Ireland, on August 7 before conducting refresher crew-training operations last month. As many as 35 takeoffs and landings were to be flown as the airline prepared for a possible resumption of scheduled services, perhaps before next month.
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 National Air Transportation Association (NATA) recently purchased the Aircraft Ground Service Guide and the Aircraft Towing Guide from Sandpiper Publications. The AGSG provides aircraft fuel requirements and capacity; performance specifications; ground-power locations and requirements; tire-pressure requirements; and weights and dimensions for pistons, turboprops and jets. The ASCG also has detailed drawings of service locations.
Piaggio Avanti, Fort Lauderdale, Fla., March 20, 2007–The NTSB determined the probable cause of the accident involving the Avantair Piaggio to be the first officer’s loss of directional control on landing, causing the left main gear to collapse. Contributing factors were the excessive use of brakes, which caused the left main tire to blow, and the captain’s inadequate supervision of the first officer.
