Although the ground crew at Montgomery Regional Airport twice discussed safety shortly before a American Eagle flight arrived at its gate on New Year’s Eve, protocols were apparently not followed when Courtney Edwards was “ingested” into the plane’s engine, according to the National Transportation Safety Board’s preliminary report of the incident released Monday.

As the pilot began shutting down the Embraer 170′s right engine, he got an alert that the front cargo door was being opened, the report stated.

American Eagle’s ground operations manual states that workers “NEVER approach an aircraft to position ground equipment next to an aircraft or open cargo bin doors until the engines are shut down and the rotating beacon(s) turned off, except when conducting an approved single engine turn,” according to the preliminary report.

The flight’s first officer then opened his cockpit window to tell a ramp agent that the plane’s engines were still running. The pilot then saw a warning light illuminate and the plane “shook violently” as the left engine immediately turned off.

The ground crew had a safety meeting 10 minutes before the plane arrived at the gate and a “safety huddle” was held shortly after the aircraft got the to gate “to reiterate that the engines would remain running until ground power was connected,” the report stated.

“It was also discussed that the airplane should not be approached, and the diamond of safety cones should not be set until the engines were off, spooled down, and the airplane’s rotating beacon light had been extinguished by the flight crew,” the report went on to say.

The accident was captured on surveillance footage showing the plane being marshalled to the gate, the NTSB said.

After a chock was placed on the nose wheel to keep the plane from moving, the ramp agent marshalling the plane walked toward the front cargo door on the right side of the airplane, near the front of the aircraft.

Meanwhile, Edwards walked toward the back of the plane with an orange safety cone before disappearing from view.

A third agent by the right wing tip was gesturing with his hand toward the back of the plane.

A fourth agent knelt near the plane’s nose wheel.

Edwards then reappeared on the footage and started to walk away from the plane towards the left wing tip before disappearing again.

The agent who was marshalling the plane could then be seen backing away from the airplane’s open forward cargo door and Edwards reappeared walking along the leading edge of the left wing and directly in front of the left engine.

“She was subsequently pulled off her feet and into the operating engine,” the report stated.

The plane’s upper rotating beacon light appeared to be illuminated throughout the accident.
