The National Transportation Safety Board is investigating two recent incidents in which airspeed and altitude indicators in the cockpits of Airbus A330s may have malfunctioned.

In both cases, the aircraft landed safely. In the first case, TAM Airlines Flight 8091 was at cruise altitude from Miami to Sao Paulo on May 21 when the aircraft lost primary speed and altitude information.

The flight crew restored primary data inputs in about five minutes using backup instruments. The flight landed in Sao Paulo with no injuries or damage.

In another incident, a Northwest plane was flying between Hong Kong and Tokyo on June 23, and the aircraft landed safely with no injuries or damage reported.

French accident investigators have said pilots aboard the ill-fated Air France Flight 447 received "inconsistent" airspeed data in crucial moments leading up to the June 1 crash off the Brazilian coast, killing all 228 aboard. Safety experts and analysts say iced-over sensors, or pitot tubes, on the A330 could have been among the factors that led to the accident.

The NTSB has released no further information.
