Data shows Amazon jet’s key braking systems did not deploy during deadly Miami crash: NTSB

The NTSB said the cargo jet’s wheel brakes were applied, but its speed brakes and thrust reversers did not deploy, according to available data.

Data shows Amazon jet’s key braking systems did not deploy during deadly Miami crash: NTSB

Introduction

Investigators from the National Transportation Safety Board (NTSB) have released preliminary findings regarding the catastrophic Amazon cargo jet crash at Miami International Airport. Data retrieved from the aircraft indicates that critical deceleration hardware failed to engage during the final moments of the flight, a development that has become central to the ongoing probe into the tragedy.

The incident, which involved Prime Air Flight 7598, resulted in a significant loss of life and a massive emergency response after the aircraft breached airport boundaries. As the investigation into why the jet’s key braking systems did not deploy during the deadly Miami crash continues, federal authorities are working to piece together the sequence of events that led to the runway overrun.

What Happened

The Amazon-contracted cargo aircraft experienced a severe overrun while attempting to land at Miami International Airport this past Sunday. Following the departure from the tarmac, the jet struck two civilian vehicles located on airport property, resulting in five fatalities and five injuries.

According to NTSB investigator Chihoon Shin, the electronic flight data provides a clear picture of the aircraft's mechanical status during the landing attempt. While primary wheel brakes were active, there was no recorded evidence that the speed brakes or thrust reversers were utilized to slow the vessel. The plane eventually came to a final stop in the vicinity of an airport parking lot after crashing through a perimeter fence.

Background

The aircraft, identified as part of the Prime Air fleet, was carrying a substantial shipment of cargo at the time of the accident. Official reports confirm that the manifest consisted primarily of contact lenses, totaling 32,222 pounds, alongside standard flight equipment. Authorities have explicitly stated that no hazardous materials were present on the aircraft, dispelling initial concerns regarding potential chemical or fire risks associated with the cargo.

The NTSB has provided details regarding the qualifications of the flight crew operating the jet. The captain, aged 55, possessed 7,145 flight hours, while the 37-year-old first officer had logged 2,655 flight hours. Both pilots held valid Class 1 medical certificates at the time of the incident.

Key Details

The following table summarizes the key metrics and personnel data released by the NTSB regarding the flight and the subsequent accident:

Category Details
Casualties 5 fatalities
Injuries 5 injured
Primary Cargo Contact lenses
Cargo Weight 32,222 pounds
Captain Age 55 years old
Captain Experience 7,145 flight hours
First Officer Age 37 years old
First Officer Experience 2,655 flight hours

Impact

The human toll of the crash has been profound, with seven of the victims identified as occupants of a van that was crushed during the overrun. The destruction of the airport fence and the secondary impact with another civilian vehicle highlight the severity of the uncontrolled landing. The incident triggered a large-scale emergency response, drawing significant attention to safety protocols and ground-level risks at major transportation hubs.

What Happens Next

The NTSB investigation is currently in a data-gathering phase. Investigators are preparing to conduct formal interviews with the flight crew to obtain their firsthand account of the landing. These discussions are considered vital for understanding how the pilots interacted with the cockpit controls and whether manual inputs were made that might explain the lack of speed brake and thrust reverser deployment.

Officials have expressed caution regarding premature conclusions. Investigator Shin emphasized that the team is still analyzing the full list of flight parameters to determine if the aircraft's performance was consistent with expected landing procedures. The agency intends to maintain a methodical approach, refraining from speculation until a comprehensive understanding of the cockpit activity and mechanical performance is achieved.
