21 Air 767 Crash: NTSB Report Details Fatal MIA Overrun

The National Transportation Safety Board (NTSB) has released its preliminary report on the Amazon Air 767 crash involving 21 Air flight 7598, which resulted in five fatalities on the ground at Miami International Airport (MIA). The investigation into the September 6, 2026, incident indicates that the Boeing 767 cargo aircraft touched down approximately 3,750 feet past the runway threshold at a ground speed of 160 knots, or roughly 184 mph. The findings suggest the flight crew failed to initiate a go-around despite the unstabilized approach, leading to a catastrophic runway overrun.

The Sequence of the Landing Roll

According to data recovered from the Flight Data Recorder (FDR), the aircraft's deceleration systems were not utilized as required during the landing roll. NTSB Investigator-in-Charge Chihoon Shin reported that there was no indication in the recorded data that speed brakes or thrust reversers were deployed. The failure to engage these critical deceleration systems, combined with the excessive touchdown point, meant the aircraft lacked the necessary remaining runway length to come to a full stop. The resulting excursion led to the aircraft striking two vehicles, causing the deaths of five people on the ground.

Operational Oversight and Safety Culture

The accident has placed 21 Air under intense regulatory and legal scrutiny regarding its pilot training, crew resource management, and overall safety culture. As a Part 121 operator under Federal Aviation Administration (FAA) oversight, the carrier is expected to maintain strict adherence to stabilized approach criteria. The incident also creates significant reputational and legal challenges for Amazon Air, which frequently outsources flight operations to third-party cargo carriers. The reliance on contract operators raises broader industry questions regarding the uniformity of safety standards and the level of oversight maintained by major logistics firms over their flight partners.

Historical Context of Runway Excursions

Runway overruns caused by late and high-speed touchdowns remain a critical safety concern in commercial aviation. The 21 Air flight 7598 accident bears similarities to previous events where flight crews failed to execute a timely go-around. In February 2020, Pegasus Airlines Flight 2193 overran a runway in Istanbul after a fast touchdown in tailwind conditions, resulting in the aircraft breaking into three pieces. Similarly, in August 2020, Air India Express Flight 1344 overran a tabletop runway in Kozhikode after touching down late and fast, resulting in 21 fatalities. These precedents underscore the high-risk nature of continuing an unstabilized landing when touchdown parameters are exceeded.

Analyzing the Deceleration Failure

The Path to the Final Accident Report

The NTSB is continuing its investigation to determine the underlying factors that led to the flight crew's decision-making process. The release of the final accident report is expected between late 2027 and 2028. This document will likely provide further clarity on the interplay between the cockpit environment, the Cockpit Voice Recorder (CVR) data, and the company's internal training protocols. The agency is currently analyzing all available parameters to determine if systemic issues within the operator's training programs contributed to the failure to deploy speed brakes or thrust reversers.

Why Ground Safety Protocols Matter

The loss of five ground personnel at MIA highlights the severe vulnerabilities of workers and perimeter traffic during runway overrun events. This accident serves as a stark reminder that the consequences of a stabilized approach failure extend far beyond the runway surface. For the aviation industry, the event signals a potential shift in how ground-side risk is integrated into airport safety management systems and how cargo carriers are audited for operational consistency.
