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.
