Amazon has temporarily suspended its partnership with 21 Air, a Miami-based cargo airline, following a fatal crash involving one of the carrier’s planes on September 6 at Miami International Airport. The incident resulted in the deaths of five people who were in a van struck by the aircraft after it overran the runway. Several others were reported injured.

The Boeing 767-300 freighter, operated by 21 Air on behalf of Amazon Air, was attempting to land after completing its third flight of the day. Earlier that day, the plane had flown from Cincinnati to Miami and then from Miami to San Juan, Puerto Rico. The aircraft, which had previously served as a passenger jet before being converted into a freighter, overshot the runway upon landing, colliding with multiple vehicles on the ground, including a van belonging to an airline cleaning company.

Amazon spokeswoman Kelly Nantel stated that the company’s decision to pause operations with 21 Air followed a review of the surrounding circumstances and ongoing support of the investigation. She emphasized that safety remains the company’s top priority. Amazon expects the suspension will have minimal effect on its customers.

The National Transportation Safety Board (NTSB) is actively investigating the crash. According to the agency, cockpit voice recordings indicate that one pilot warned the other about excessive speed prior to landing and that the pilots considered aborting the landing shortly after touchdown. The aircraft was traveling at about 138 miles per hour at the time the brakes were released. The cause of the accident has not yet been determined, and the NTSB cautions that a final report could take a year or more.

21 Air has expressed confidence in its safety policies, procedures, and training and stated that it is focused on supporting the affected families, cooperating with the NTSB, and maintaining communication with clients such as Amazon. The airline operates a fleet of approximately 17 aircraft and serves multiple logistics companies, including DHL Express. DHL has confirmed that it is assessing its partnerships but declined further comment, citing the sensitivity of the ongoing investigation.

Owned by billionaire Jim Crane, who also owns the Houston Astros baseball team, 21 Air has faced safety concerns in the past, as indicated by whistleblower complaints filed with the U.S. Labor Department. The investigation into the Miami crash continues as authorities seek to ascertain contributing factors and prevent future incidents.
