Fatal Amazon cargo jet crash: new data reveals pilot warnings about excessive speed before Miami runway overrun

A recent investigation update from the US National Transportation Safety Board (NTSB) has shed new light on the Amazon cargo plane crash that occurred in Miami, Florida, on a Sunday. Fresh flight data indicates that a pilot repeatedly expressed concerns about the aircraft’s excessive speed during its final approach before it overran the runway.

The Boeing 767-300, operating as Amazon Prime Air Flight 7598, ultimately crashed into ground vehicles and burst into flames, resulting in multiple fatalities and injuries. This new information highlights critical moments inside the cockpit leading up to the catastrophic event.

The NTSB’s ongoing inquiry is meticulously analyzing all available data, including cockpit conversations and flight parameters, to determine the precise sequence of events and contributing factors that led to the tragic accident.

Alarms and unheeded warnings

According to the NTSB’s initial findings, one pilot onboard the ill-fated flight issued multiple verbal warnings to the other pilot regarding the “aircraft’s excessive speed” as the plane approached the runway. These cautions were reportedly made throughout the latter part of the flight recording, painting a picture of escalating concern within the cockpit.

Despite these repeated alerts, investigators noted an “inconsistent verbal response” from the second pilot. This lack of clear acknowledgment or action was compounded by the activation of an altitude alarm, signaling a potentially dangerous situation as the aircraft descended towards Miami International Airport.

High speed on final approach

The flight data recorder captured the Boeing 767-300’s landing speed at 158 knots (approximately 292 km/h). Aviation experts consulted in the wake of the incident have indicated that this velocity is on the higher end of the acceptable range for a commercial jetliner of this type during a landing sequence, suggesting a significant contributing factor to the subsequent overrun.

Automated safety systems on the aircraft also triggered critical warnings during the final minutes before impact. An electronic “sink rate, sink rate” callout alerted the crew to an unsafe speed of descent, a standard procedure designed to prevent hard landings or uncontrolled approaches. This warning would have been audible to both pilots, emphasizing the severity of the situation.

Further exacerbating the precarious approach, an electronic “too low terrain” callout was also heard. This automated verbal alert signifies that the aircraft is flying too close to the ground without being properly configured or prepared for landing, often due to insufficient altitude or an improper glide path. The combination of these alarms and the pilot’s warnings paints a concerning picture of the final moments.

Flap deployment under scrutiny

Aviation experts are also examining the data concerning the deployment of the aircraft’s flaps. Flaps are crucial aerodynamic devices located on the trailing edge of the wings, designed to increase lift and drag, thereby allowing an aircraft to slow down and maintain control at lower speeds, essential for a safe landing. Their proper deployment at the correct time is fundamental to a controlled descent.

Initial analysis of the flight data suggests that the flap deployment occurred “much later in the accident sequence” than typically expected. This delay could indicate that the pilots were actively responding to the realization that their approach speed was dangerously high, attempting to mitigate the situation by deploying flaps belatedly to increase drag and reduce velocity. However, by that point, the aircraft’s momentum may have already rendered such actions less effective in preventing the overrun.

The disastrous sequence on the ground

After overshooting the designated runway, Amazon Prime Air Flight 7598 continued its uncontrolled trajectory across the airport grounds. The massive cargo plane initially struck various pieces of equipment on the ground, causing significant damage and scattering debris. Its destructive path then led it to collide with a white Ford van, which was carrying airport personnel, tragically claiming lives.

The aircraft proceeded to breach the airport’s perimeter fence, demonstrating the immense force and speed with which it was still moving. Following this, it struck a Toyota Corolla before finally coming to a halt approximately 1,300 feet (394 meters) beyond the end of the runway. The extensive damage to multiple vehicles and infrastructure underscores the severity of the crash and the broad impact zone.

Identifying the victims

The tragic incident resulted in the deaths of five individuals and injuries to five others. Authorities in Miami identified the five fatalities as members of a plane-cleaning crew who were in the Ford van that bore the brunt of the collision with the out-of-control aircraft. Their presence on the tarmac at the moment of the overrun placed them directly in harm’s way.

The victims were identified as Rolando Aleman Leon, 55; Yoel Rodriguez Naranjo, 53; Julio C Pineda, 75; Carlos Acosta Fajardo, 53; and Javierkys Reyes Quevedo, 47. Each of these individuals represented a profound loss to their families and the airport community, highlighting the human cost of aviation accidents.

The NTSB’s investigation into the incident extends beyond the mechanical and operational aspects of the flight, encompassing the full scope of the event, including the impact on ground personnel. Understanding how such incidents unfold on the ground is critical for implementing enhanced safety protocols for airport workers.

This phase of the investigation seeks to understand not only why the plane overran the runway but also how airport ground operations and safety measures might be improved to prevent similar tragedies in the future, especially given the unpredictable nature of such emergencies.

Broader implications for air cargo safety

The detailed findings from the NTSB’s investigation into this Amazon cargo plane crash are expected to have significant implications for air cargo operations and aviation safety standards globally. Understanding the interplay between pilot actions, automated warnings, and aircraft performance in high-stress situations is paramount for preventing future incidents. The aviation industry constantly evolves its safety protocols based on lessons learned from such events, emphasizing continuous improvement in training, technology, and operational procedures.
