The first officer of the Learjet stated that he was walking to the airplane with two passengers, and the five remaining passengers were following behind them. As some of the passengers were about to board the airplane, he heard a loud roar and felt a strong, warm gust. He turned around and saw one of the passengers on the ground. He stated he initially thought the Bombardier only had its auxiliary power unit running and believed the airplane was far enough away.
The FO also stated the injured person was briefly unconscious, A second passenger was blow over but only suffered cuts to her knees.
The Bombardier aircraft had arrived to drop one passenger off:
They shut down the left engine and deplaned the passenger, restarted the left engine, and taxied back to the runway. During the entire stop, the rotating beacon was on and the right engine was operating. The captain stated that he used normal breakaway power to get the airplane out of the parking spot, then taxied at normal speeds.
An FAA inspector commented that there was a procedure “for marshalling the transit aircraft in, but not marshalling them out of the ramp”.
The NTSB Probable Cause was:
The first officer’s failure to maintain a safe distance from a large turbine-powered airplane while escorting passengers, resulting in a passenger encounter with jet blast.
