Amazon has suspended its partnership with cargo carrier 21 Air following a runway accident at Miami International Airport that killed five people last week.

A Boeing 767 operated by 21 Air overshot the runway on September 6, traveling roughly 1,300 feet (396 meters) past its end before striking a van carrying workers from a plane cleaning company. All five fatalities were occupants of the van. Five others were injured.

"After the tragic incident last weekend, we've spent time supporting the investigation and reviewing some of the surrounding circumstances, and we've decided to pause our operations with 21 Air, the operator of Flight 7598," Amazon spokesperson Kelly Nantel said in a statement. "We'll continue working to support the investigation and everyone affected."

North Carolina-based 21 Air had flown packages for Amazon since 2024. The company did not immediately respond to a request for comment about Amazon's decision.

The National Transportation Safety Board is leading the investigation. Investigators are expected to review the aircraft's ownership history, weather conditions at the airport, maintenance records, and 21 Air's operations.

Flight information released by the NTSB on September 9 revealed that one of the pilots warned his counterpart they were traveling too fast during the approach and after touchdown. Cockpit audio recordings also captured a series of automated warnings about the speed of descent and approaching terrain.

The full transcript of the cockpit conversation is not expected to be released until later in the investigation.

The 32-year-old Boeing 767 was originally built to carry passengers and flew for several airlines in foreign countries for more than two decades before being converted to a cargo aircraft in 2015, according to flight-tracking site Flightradar24.
