NTSB Issues Investigative Update on B-767 Runway Excursion Accident in Miami

WASHINGTON (Sept. 9, 2026) — The National Transportation Safety Board is providing the following update on its investigation into the Sept. 6 runway excursion accident involving 21 Air Flight 7598, a Boeing 767-33A cargo airplane, at Miami International Airport.The following information from the cockpit voice recorder (CVR) and flight data recorder (FDR) is preliminary and subject to change.The NTSB recovered the CVR and FDR from the accident site and transported them to the NTSB’s Vehicle Recorder Laboratory in Washington, DC, where they were successfully read out. The aircraft was equipped with an Acron Aviation (formerly L3Harris) model FA2100 CVR and an Ontic (formerly Honeywell) model SSFDR FDR.The CVR contained more than 2 hours of good quality audio across four channels.The FDR contained approximately 54 hours of data and recorded more than 400 parameters. The NTSB will convene a CVR group in the near future at NTSB headquarters in Washington, DC, to review the accident flight recording and produce a written transcript. A summary of select events captured on the CVR during the final few minutes of the recording is provided below. All times are referenced relative to the end of the CVR recording. The times and descriptions are preliminary and subject to change.Approximate Time to End of CVR Recording (mm:ss)Observation06:02A pilot called for flaps to be set to 1 degree.04:18The flight crew checked in with Miami tower and were cleared toland on runway 30.02:53A pilot called for flaps to be set to 5 degrees.02:37The flight crew lowered the landing gear.02:14A pilot called for flaps to be set to 15 degrees.01:42A pilot called for flaps to be set to 20 degrees, and the other pilot cautioned they were too fast. The other pilot made additional comments regarding the aircraft’s excessive speed throughout the remainder of the recording. There was not a consistent verbal response to the comments about speed.01:23Sounds consistent with autopilot disconnect.01:12Electronic “one thousand” callout.01:04Electronic “sink rate sink rate” callout.00:58Electronic “five hundred” callout.00:57Electronic “sink rate sink rate” callout.00:54Electronic “one hundred” callout.00:50Electronic “minimums” callout.00:48Electronic “too low terrain” callout. Annunciated four times.00:41A pilot called for flaps to be set to 30 degrees.00:40Electronic “forty” callout.00:39Electronic “too low terrain” callout.00:36Electronic “ten” callout.00:31Sounds similar to the aircraft touching down.00:15A pilot called for a go-around.00:10Sounds similar to the aircraft departing the paved surface.00:00The CVR recording ended.A summary of select events captured on the FDR during the final few minutes of the FDR recording is provided below. All times are referenced relative to the end of the FDR recording. Note that the CVR and FDR times have not been precisely synchronized. The times and descriptions are preliminary and subject to change.Approximate Time to End of FDR Recording (mm:ss)Observation00:30The nose and right main gear touched down at a groundspeed of 158 knots.00:23The brakes were applied at a groundspeed of 146 knots.00:19The left main gear touched down at a groundspeed of 134 knots.00:15Brakes were released at a groundspeed of 120 knots and throttles were increased to a value consistent with go-around thrust.00:11The throttles were reduced to idle power and the brakes were re-applied. The groundspeed was 117 knots. The throttles remained at idle, and brakes remained applied until the end of the recording.00:07Recorded lateral, longitudinal, and vertical acceleration values changed markedly; the FDR data indicated a groundspeed of 96 knots.00:00The FDR recording ended. The final recorded groundspeed was 65 knots. There was no indication in the recorded data that speed brakes or thrust reversers were deployed. Additional information, including video of media briefings, photos and other factual materials, is available on the accident investigation webpage.To report an incident/accident or if you are a public safety agency, please call 1-844-373-9922 or 202-314-6290 to speak to a Watch Officer at the NTSB Response Operations Center (ROC) in Washington, DC (24/7).
