The US Aircraft Accident Investigation Board (NTSB) has published an initial interim report on the death of the Envoy Air employee who was "sucked" into an engine of the N31NN on December 2022, 264. On that day, this Embraer 175 was scheduled to fly from Montgomery Regional Airport to Dallas/Fort Worth under flight number AA3408. There were 59 passengers and four crew members on board. A ramp worker was sucked into an engine of the regional jet and died as a result. Colleagues who immediately rushed to the man's aid were unfortunately able to confirm his death. Preparations for takeoff were immediately canceled due to the tragic accident. No passengers or crew members were injured in the accident, which occurred on the apron. However, the ramp agent lost his life. Responsibility for the Embraer 175 lay with Piedmont Airlines, a subsidiary of the American Airlines Group. However, the operational implementation was carried out by the sister company Envoy Air. According to the NTSB, the E175 had a non-functional auxiliary power unit (APU), which meant that it had to be operated with ground power after the required two-minute engine cool-down phase when it arrived at the gate. When the aircraft arrived at the gate, three ramp agents were present and all three were outside the security area. When the captain switched off the second (right) engine, the Engine and Crew Alert System (EICAS) indicated that the forward cargo door had been opened, although the first engine was still running. The first officer opened his cockpit window to inform the ramp agent who opened the cargo door that the left engine was still running.
