Engineers also checked lights, the windshield and passenger windows.Īll four powerplants underwent borescope checks and examination of the compressor, combustor, turbine and vanes. The 747 operated up to an altitude of 40,000ft in a series of staged climbs to expose the jet to various layers of the atmosphere, in a bid to assess whether the volcanic ash from Iceland is liable to affect flight safety.īA says the 747 underwent a full structural survey at Heathrow, including compilation of a photographic record, covering critical areas such as the wing and stabiliser leading edges, sensors, engine inlets and radome. "We believe airlines are best-positioned to assess all available information and determine what, if any, risk exists to aircraft, crew and passengers." "Since airspace was closed on our assessment is that the risk has been minimal and can be managed by alternative procedures to maintain the highest safety standards," he says. Rolls-Royce is to analyse the engine oil and fuel filters from the aircraft.īA says that information from the flight recorders indicates that all four RB211s performed "without fault for the duration of the flight" and without any degradation of performance.Ĭhief executive Willie Walsh is citing the technical analysis to support an argument that the blanket restrictions on European airspace are unnecessary. "All these checks showed no deterioration from that previously recorded at London Heathrow," says BA. Technicians conducted a borescope inspection of the engines after the flight.
