Ground the Airbus?


Ground the Airbus?

Since entering service in 1974 with many technological innovations, such as computerized fly-by-wire control systems, user-friendly cockpits, and extended use of composite materials, 5,717 aircraft have been manufactured by Airbus, an European aerospace company. More than 5,100 Airbuses remain in service.

Not including losses attributable to terrorism, rebellion or military action, Airbuses have been involved in 23 fatal crashes causing the deaths of 2,584 passengers, crew members and people on the ground. In addition, there have been five nonfatal accidents causing 21 serious injuries.

While the overall number of accidents and fatalities are not disproportionate to the crash experience of Boeing aircraft, three of the Airbus crashes involved a separation of the composite vertical stabilizer (tail fin) from the fuselage. Five hundred, or one in five of the Airbus deaths, including 228 from Air France Flight 447, resulted from these three crashes.

In addition, Airbus composite stabilizers, rudders and couplers have also been involved in a number of other emergency in-flight incidents that did not lead to crashes, injuries or deaths.

There is now a question whether all Airbus aircraft equipped with composite stabilizers and rudders should be grounded until the cause of the crash of Flight 447 can be identified and it can be determined if the aircraft can be inspected, safely repaired, and returned to service.
