Background
The flightcrew was operating a continuous duty overnight schedule. The previous day, both pilots awoke during the morning hours, did not sleep during the day, and reported for duty at approximately 2200 for a flight scheduled at 2246. That flight was delayed, and the crew arrived at Baltimore/Washington International Thurgood Marshall Airport (BWI) around 0100. They went to sleep about 0130 and awoke at approximately 0445 for the accident flight, which was scheduled to depart at 0610.
Flight Details
During the approach phase, the runway visual range (RVR) dropped below minimums, and the flightcrew was issued holding instructions. While flying toward the holding fix, the RVR increased. The air traffic control (ATC) specialist offered the flightcrew the Instrument Landing System (ILS) approach but advised that they might be too high. The captain accepted the approach clearance. The ATC specialist asked if the flightcrew would be able to make the approach from their position, to which the captain gave an affirmative reply.
Approach and Landing
The captain continued the entire approach with excessive altitude, airspeed, and rate of descent, while remaining above the glide slope. This was contrary to company procedures, the instrument approach procedure, Federal Aviation Regulations (FAR) 91.175, and four audible warnings from the airplane's Ground Proximity Warning System (GPWS). During the approach, the first officer failed to make the required callouts, including a missed approach callout. The airplane landed approximately 7,000 feet beyond the approach end of the runway at 157 knots and subsequently overran the runway.
Pilot Statements
During post-accident interviews, both pilots stated that they were fatigued.
