October 26, 2009

In its continuing investigation of an Airbus A320 that overflew the Minneapolis-St Paul International/Wold-Chamberlain Airport (MSP), the National Transportation Safety Board has developed the following factual information: On Wednesday, October 21, 2009, at 5:56 pm mountain daylight time, an Airbus A320, operating as Northwest Airlines (NWA) flight 188, became a NORDO (no radio communications) flight at 37,000 feet. The flight was operating as a Part 121 flight from San Diego International Airport, San Diego, California (SAN) to MSP with 144 passengers, 2 pilots and 3 flight attendants.

Both pilots were interviewed separately by NTSB investigators yesterday in Minnesota. The following is an overview of the interviews:

The Safety Board is interviewing the flight attendants and other company personnel today. Air traffic control communications have been obtained and are being analyzed. Preliminary data from the cockpit voice recorder (CVR) revealed the following:

The FDR captured the entire flight which contained several hundred aircraft parameters including the portion of flight where there was no radio communication from the flight crew. Investigators are examining the recorded parameters to see if any information regarding crew activity during the portion of flight where radio contact was lost can be obtained.

The Safety Board's investigation continues.
