Rudder Could Be Cause of Air France Crash

There's been a pattern of irregularities linked to the tail fin, but Airbus says it's too soon to know.

NEW YORK, NY — As they work to unravel the mystery of Air France Flight 447, aviation analysts and pilots are now urging investigators to focus attention on the plane's tail fin, known as the vertical stabilizer, in addition to the design of the Airbus's computerized flight controls.

The vertical stabilizer is one of the largest intact pieces of the plane recovered so far, and the Times of London reported this week that "one of the 24 automatic messages sent from the plane minutes before it disappeared pointed to a problem in the 'rudder limiter,' a mechanism that limits how far the plane's rudder can move."

Aviation analysts note that several Airbus 300 series jets have had tail fin and rudder problems in the past. (The rudder is the flight control on the vertical stabilizer, or tail fin.)
