The pilots flying an Amazon-branded cargo jet that crashed on approach to Houston had no wind information from either the control tower or their own cockpit displays, according to the National Transportation Safety Board's final report on the accident.

The Atlas Air Boeing 767-300 freighter, operating as Flight 3591, crashed into Trinity Bay near Anahuac, Texas, on February 23, 2019, killing all three people aboard. The aircraft was descending toward Houston's George Bush Intercontinental Airport on a flight from Miami when it went down about 30 miles short of the runway.

NTSB investigators determined the crew's flight displays were not showing wind data at the time of the accident. The tower, meanwhile, had not passed along current wind information, leaving the pilots without a key input for managing their approach.

The board's findings point to a broader set of factors in the crash. Investigators concluded the pilots lost control of the aircraft after an inadvertent activation of the go-around mode during the descent, followed by a series of crew actions that put the jet into a steep dive from which recovery was not possible.

The accident drew attention to the rapid growth of Amazon's air cargo network, which relies on contracted carriers such as Atlas Air to move freight between the company's distribution hubs. Atlas Air operates the 767 freighters under Amazon's "Prime Air" brand, though the aircraft carry Amazon livery and fly dedicated routes for the e-commerce giant.

The NTSB has previously raised concerns about pilot training and cockpit workload management in the accident sequence. The final report consolidates the board's conclusions about the chain of events that led to the crash.

For Amazon, the accident highlighted the operational risks that come with building a dedicated air network to support its one- and two-day delivery promises. The company has continued to expand its air cargo operations, adding flights and airport facilities as it shifts more of its logistics in-house.

The findings on wind information gaps add to ongoing industry discussion about how weather data reaches flight crews during critical phases of flight, particularly on busy cargo approaches into major hubs.
