The National Transportation Safety Board is investigating a cargo flight accident at Miami International Airport involving 21 Air LLC Flight 7598. The Boeing 767-33A aircraft overran the end of Runway 30 during its landing from San Juan, Puerto Rico.
According to an investigative update, the NTSB recovered the cockpit voice recorder (CVR) and flight data recorder (FDR) from the accident site. These recorders were successfully read out at the NTSB Vehicle Recorder Laboratory in Washington, DC. The CVR contained over two hours of audio across four channels, while the FDR contained approximately 54 hours of data covering more than 400 parameters.
Flight data indicates that the aircraft's nose and right main gear touched down at a groundspeed of 158 knots. The FDR recorded that brakes were applied at 146 knots, and the left main gear touched down at 134 knots. Data showed that speed brakes or thrust reversers were not deployed. The final recorded groundspeed was 65 knots.
Cockpit voice recorder transcripts provided in an undated update show the flight crew was cleared to land on runway 30. During the final minutes of the recording, one pilot cautioned that the aircraft was too fast, though there was no consistent verbal response to the comments regarding excessive speed. The recording also captured multiple 'too low terrain' callouts prior to the aircraft departing the paved surface.
