Amazon Air 767 overruns Miami runway, kills five on the ground

A Boeing 767-300 freighter operating as Prime Air Flight 7598 left the paved surface of Runway 30 at Miami International Airport at about 1.53 p.m. Eastern Time on Sunday, 6 September, crossed a perimeter road used by warehouse traffic, struck several vehicles and caught fire. Miami-Dade officials later counted five dead on the ground and five injured. Three of the injured were in critical condition on Sunday night.

The two-person crew survived. Miami-Dade Fire Chief Ray Jadallah said both pilots were trapped in the cockpit after the aircraft came to rest on its collapsed nose gear, and that at least two people were trapped in vehicles the jet hit. More than 60 rescue units and about 200 personnel answered the call. Firefighters were still dealing with a fuel leak late on Sunday afternoon.

The aircraft was N1997A, a 32-year-old Boeing 767-33AER converted to a Bedek Designed Special Freighter and named Amazon One. It left Luis Muñoz Marín International Airport in San Juan, Puerto Rico, with no passengers. 21 Air, a North Carolina cargo carrier with an operations base in Miami, flew the sector for Amazon Air. Kelly Nantel, speaking for Amazon, said the company was still gathering details. Greg Chin, a spokesman for the airport, identified the flight and said all runways and taxiways were closed by 3 p.m., with a ground stop in force.

Flights resumed by Sunday evening. The disruption did not. FlightAware recorded 232 cancellations in the following 24 hours. By noon on Monday, inbound flights to Miami were delayed by more than five hours on average. Transportation Secretary Sean Duffy warned of delays on the last day of the Labor Day weekend. Miami is the third-busiest freight airport in the United States, and the wreckage sat near a parking lot tied to an Amazon logistics yard at the northwestern edge of the field.

What the recorders and the approach path show

Flightradar24's track put the jet above the normal glide path for Runway 30 on the way in, then showed a drop back toward the published profile. The runway is more than 9,000 feet long. Investigators will have to explain why a landing roll on that distance ended beyond the airport fence.

The National Transportation Safety Board sent a go-team led by chair Jennifer Homendy and scheduled a briefing for 4 p.m. Eastern on Monday, 7 September. The Federal Aviation Administration is running a parallel inquiry. The questions already on the table are ordinary and specific: wind and runway state at touchdown, brake and thrust-reverser performance on a converted 767, weight and balance, crew communications, and the maintenance history of an airframe that flew passengers from 1994 to 2015 before conversion by Israel Aerospace Industries in Tel Aviv.

That history is not decorative. The jet was the first aircraft Amazon unveiled in Prime Air colours, in August 2016. Its registration echoes the year of the company's public listing. Amazon's cargo model leases capacity; a vendor holds the air operator certificate, the crew and the maintenance burden. 21 Air is one of nine flight vendors in a network that moves more than 250 sectors a day. A runway excursion that kills people off the airport changes the risk calculus for every converted passenger jet in that fleet, not only this tail number.

Ground risk at a freight hub

The dead were not in the cockpit. They were on a road that sits where airside pavement meets the warehouse belt that grew up around MIA. Cargo airports compress that boundary. Tractor-trailers, contractor vans and shift workers share space a few dozen metres from threshold lights. When a 767 leaves the runway at landing speed, that road is no longer a buffer. It is an impact zone.

Officials declined to name the dead on Sunday. Mayor Daniella Levine Cava called it a difficult day for Miami-Dade. Video from local stations showed black smoke and the smile logo on the tail. Later stills showed the fuselage largely intact, nose down, beside two trucks. Appearance is a poor guide to energy. Five people on the ground did not survive the transfer of that energy from the landing gear to the road.

Labor Day traffic compounded the operational cost. Vacationers who had treated Miami as a hub found themselves rebooked or stranded. The airport's freight rank means the same overrun also delayed parcels that would have left Florida on Sunday night. Those delays do not belong in the accident report. They do belong in any account of what a single landing on Runway 30 now costs.

The next facts will come from the cockpit voice recorder, the flight data recorder and the wreckage survey Homendy's team began on Monday. Until those instruments speak, the known sequence is short. A 32-year-old freighter arrived from San Juan. It did not stop on 9,000 feet of concrete. Five people on the far side of the fence are dead.
