Airbus Glitches Probed on 2 New Flights

Federal investigators are probing two recent incidents in which speed and altitude sensors malfunctioned on Airbus 330s, USA Today reports. The failures, one on a Northwest Airlines flight and one on Brazil's TAM Airlines, are similar to those being investigated in the crash of an Air France A330 earlier this month.

The planes managed to land safely with no injuries in both incidents. The investigation into the crash of the Air France jet is focusing on air pressure sensors, known as Pitot tubes, that apparently failed shortly before the plane went down. Airbus advised airlines to replace the tubes last year because they could malfunction in bad weather, but many failed to do so until recently. (More Airbus A330 stories.)
