On June 1, 2014, about 1400 eastern daylight time, an employee from the fixed base operator responding to a DeHavilland DHC-6-200 airplane, N223AL, received fatal injuries when she was struck by an operating propeller blade as she walked toward the cockpit while the airplane was standing on a ramp at the Middletown Regional Airport/Hook Field (MWO), near Middletown, Ohio. The airplane sustained minor propeller damage. The airplane was registered to and operated by Win Win Aviation Inc. under the provisions of 14 Code of Federal Regulations Part 91 as a skydiving flight. Day visual flight rules conditions prevailed at the time of the accident and the flight was not operating on a flight plan. The local skydiving flight was standing on the MWO ramp while waiting for passengers to board when the accident occurred.
The airplane landed from a skydiving flight with a remaining passenger after three parachutists had jumped from the airplane. The engine was not shut down and the airplane was pointed toward the vehicle waiting for the passenger to deplane. When the passenger exited the airplane, a ground crewmember leaned toward the airplane to talk to the pilot while the passenger went around the right side of the airplane.
After a parachute drop flight, the airplane taxied back to the ramp area. The airplane was parked on the ramp, with the engine running, while the next group of parachutists were boarding the airplane. During that time, a parachutist who had just landed, contacted the propeller and sustained a serious injury.
The helicopter’s main rotor blade contacted a photographer fatally injuring him. Before lift off, ground crew informed the pilot that there were four canopies in the vicinity of the takeoff area. The pilot immediately took off and began following a mowed grass area adjacent to an area of corn in which the photographer was standing in and unseen by the pilot.
After landing at night and stopping on the ramp, a passenger was seriously injured after walking into the propeller blade after exiting the aircraft.
A de Havilland DHC-6 and a Beech King Air 90 were to make a formation air drop of skydivers from 14,000 feet msl. The de Havilland was to be the lead aircraft with the King Air in trail. As the skydivers prepared to exit, the King Air was traveling faster than the de Havilland, and the pilot of the King Air had to pitch up and bank right to avoid the de Havilland.
During the loading of 17 parachutists, a 31-year-old male parachutist notified the loader/jump master that on his next jump he would have a smoke canister on the airplane and that the pilot should be notified.
The flight returned from dropping parachutists, and the pilot left the engines running as the next load of parachutists loaded. A passenger, who had ridden on the previous flight, was instructed by the pilot to exit through the rear door and that ground personnel would direct her.
Three observers accompanied the aircrew & other passengers on a flt to transport skydivers aloft. Prior to the flt, all 3 of the observers were briefed not to exit the acft until the engines were secured. However, 1 of the 3 discussed the need to move a cessna 172 at the completion of the flt. After returning from the flt, the aircrew stopped the plane on the ramp. While the engines were still running, the occupant that wanted to move the cessna exited the acft. Unbeknown to him & the plt, the other 2 occupants also exited the acft. One of them walked into the arc of the left propeller & received a fatal head injury.
