The National Transportation Safety Board (NTSB) has completed an initial review of the cockpit voice recorder from the Atlas Air Boeing 767-300ER Freighter that crashed southeast of Houston on 23 February, and will analyse the flight data recorder that was recovered on 3 March.
The agency says that “crew communications consistent with a loss control of the aircraft” began 18s prior to the end of the cockpit voice recording, which is 2h long. The audio is poor during certain parts including leading up to the crash in Trinity Bay. Engineers filtered the audio to determine some of what the flight crew said to each other during hard to follow discussions. Air traffic controllers were providing the crew radar vectors for the runway 26L approach into Houston Intercontinental airport.
On 3 March, an NTSB team fished the flight data recorder out of Trinity Bay and the device arrived at the agency's lab in Washington DC that day. Investigators on 4 March disassembled the memory module from the flight data recorder, cleaned it and downloaded the data on 4 March. Flight data recorders capture information about an aircraft from numerous flights before they are overwritten, so investigators will sift among 17 flights for data about the performance of the 767 including its engines and flight controls.
The NTSB says it expects to issue an investigate update "in a few days", after investigators verify and validate the data.
The Atlas 767F was operating flight 3591, an Amazon Prime Air-branded flight from Miami to Houston Intercontinental airport. Three people died in the crash: captain Ricky Blakely, first officer Conrad Jules Aska and Mesa Airlines pilot Sean Archuleta.
