The National Transportation Safety Board (NTSB) has released a preliminary summary of selected cockpit voice and flight data recorder findings from the fatal Amazon.com Inc. (NASDAQ:AMZN) “Prime Air” crash in Miami that claimed five lives and injured five individuals.

Pilot Warned Plane Was Too Fast

In a statement released on Wednesday, the agency said that the cockpit voice recordings were “preliminary” and could be “subject to change.” The agency said that approximately 1:42 minutes before the end of the voice recording, a pilot cautioned that the aircraft was “too fast” as it approached. The report did not specify which pilot issued the warnings.

“The other pilot made additional comments regarding the aircraft’s excessive speed throughout the remainder of the recording,” the NTSB said, adding that there was no “consistent verbal response” to the reminders about speed. The statement also mentioned that “too low terrain” was “annunciated four times.”

“Approximately 15 seconds before the end of the CVR recording, a pilot called for a ‘go-around,’ an attempt to abort the landing and climb away, as also pointed out by the flight data recordings of the Boeing Co. (NYSE:BA) 767 aircraft operated by 21Air LLC.
