NTSB Narrative Summary Released at Completion of Accident
The airplane was substantially damaged when a baby stroller being off-loaded from the cargo compartment inadvertently entered the right propeller arc and was struck by the operating propeller. The operator reported that after the airplane's engines had been started, it was discovered that a baby stroller had not been off-loaded. The station agents notified the captain, who shut down the left engine. An agent accessed the cargo compartment, located at the left, rear portion of the airplane. While he was exiting the compartment, the station agent lost his balance and dropped the stroller onto the ramp. The stroller landed on its wheels and was blown under the fuselage by the wind and into the right main landing gear. The stroller was subsequently blown forward into the right propeller arc, where the operating propeller struck it. Fragments from the stroller impacted the airplane's fuselage, puncturing three holes and causing several dents in the pressurized fuselage. The wind speed was about 20 knots, gusting to 31 knots, at the time of the accident.
NTSB Probable Cause Narrative
The station agent's inability to maintain control of the stroller when he lost his balance exiting the airplane's cargo compartment, allowing it to be blown into the operating right propeller. A factor was the high, gusty winds.
