Investigators over the weekend began interviewing crew members of the Delta Air Lines plane that slid off a runway at LaGuardia Airport last week, resulting in minor injuries to passengers and a major – if temporary – shutdown of the airport.
The National Transportation Safety Board (NTSB) says it has secured the flight data and cockpit voice recorders from the aircraft. They have been sent to the Board’s lab in Washington D.C., where they’ll be downloaded and their contents studied.
The plane, which was en route from Atlanta, veered off the runway during its landing sequence with 127 passengers on board. The airport was shut down for 24 hours while conditions were assessed for safety.
According to an investigative update released by the Board:
• The airplane has been moved to a hangar for more detailed examination and further documentation by investigators.
• A second team of investigators with expertise in operations, human performance, and maintenance flew to Delta Air Lines’ headquarters in Atlanta, GA and has begun conducting crew interviews and reviewing the maintenance records for the accident airplane.
• The CVR was successfully downloaded. It contains two hours of good quality recordings and captured the entire flight.
• The FDR, a 25 hour tape-based recorder, was downloaded. It captured the entire flight and approximately 50 parameters of data, including things such as airspeed, altitude, heading, and information on engines and flight controls.
• The audition of the recorders is underway and factual data from the recorders will be released when available.
Parties to the investigation include the Federal Aviation Administration, Delta Air Lines, the Air Line Pilots Association, Boeing, and Pratt & Whitney.
