WASHINGTON (Sept. 9, 2026) — The National Transportation Safety Board is providing the pursuing update connected its investigation into the Sept. 6 runway excursion mishap involving 21 Air Flight 7598, a Boeing 767-33A cargo airplane, astatine Miami International Airport.
The pursuing accusation from the cockpit sound recorder (CVR) and flight information recorder (FDR) is preliminary and taxable to change.
- The NTSB recovered the CVR and FDR from the mishap tract and transported them to the NTSB’s Vehicle Recorder Laboratory successful Washington, DC, wherever they were successfully publication out.
- The craft was equipped pinch an Acron Aviation (formerly L3Harris) exemplary FA2100 CVR and an Ontic (formerly Honeywell) exemplary SSFDR FDR.
- The CVR contained much than 2 hours of bully value audio crossed 4 channels.
- The FDR contained astir 54 hours of information and recorded much than 400 parameters.
- The NTSB will convene a CVR group successful the adjacent early astatine NTSB office successful Washington, DC, to reappraisal the mishap flight signaling and nutrient a written transcript.
A summary of prime events captured connected the CVR during the final fewer minutes of the signaling is provided below. All times are referenced comparative to the extremity of the CVR recording. The times and descriptions are preliminary and taxable to change.
| 06:02 | A aviator called for flaps to beryllium group to 1 degree. |
| 04:18 | The flight unit checked successful pinch Miami building and were cleared to land connected runway 30. |
| 02:53 | A aviator called for flaps to beryllium group to 5 degrees. |
| 02:37 | The flight unit lowered the landing gear. |
| 02:14 | A aviator called for flaps to beryllium group to 15 degrees. |
| 01:42 | A aviator called for flaps to beryllium group to 20 degrees, and the different aviator cautioned they were excessively fast. The different aviator made further comments regarding the aircraft’s excessive velocity passim the remainder of the recording. There was not a consistent verbal consequence to the comments astir speed. |
| 01:23 | Sounds accordant pinch autopilot disconnect. |
| 01:12 | Electronic “one thousand” callout. |
| 01:04 | Electronic “sink complaint descend rate” callout. |
| 00:58 | Electronic “five hundred” callout. |
| 00:57 | Electronic “sink complaint descend rate” callout. |
| 00:54 | Electronic “one hundred” callout. |
| 00:50 | Electronic “minimums” callout. |
| 00:48 | Electronic “too debased terrain” callout. Annunciated 4 times. |
| 00:41 | A aviator called for flaps to beryllium group to 30 degrees. |
| 00:40 | Electronic “forty” callout. |
| 00:39 | Electronic “too debased terrain” callout. |
| 00:36 | Electronic “ten” callout. |
| 00:31 | Sounds akin to the craft rubbing down. |
| 00:15 | A aviator called for a go-around. |
| 00:10 | Sounds akin to the craft departing the paved surface. |
| 00:00 | The CVR signaling ended. |
A summary of prime events captured connected the FDR during the final fewer minutes of the FDR signaling is provided below. All times are referenced comparative to the extremity of the FDR recording. Note that the CVR and FDR times person not been precisely synchronized. The times and descriptions are preliminary and taxable to change.
| 00:30 | The chemoreceptor and correct main cogwheel touched down astatine a groundspeed of 158 knots. |
| 00:23 | The brakes were applied astatine a groundspeed of 146 knots. |
| 00:19 | The near main cogwheel touched down astatine a groundspeed of 134 knots. |
| 00:15 | Brakes were released astatine a groundspeed of 120 knots and throttles were accrued to a worth accordant pinch go-around thrust. |
| 00:11 | The throttles were reduced to idle powerfulness and the brakes were re-applied. The groundspeed was 117 knots. The throttles remained astatine idle, and brakes remained applied until the extremity of the recording. |
| 00:07 | Recorded lateral, longitudinal, and vertical acceleration values changed markedly; the FDR information indicated a groundspeed of 96 knots. |
| 00:00 | The FDR signaling ended. The final recorded groundspeed was 65 knots. There was nary denotation successful the recorded information that velocity brakes aliases thrust reversers were deployed. |
Additional information, including video of media briefings, photos and different actual materials, is disposable connected the accident investigation webpage.
