Robinson R44 crash near Johnson, KS, United States

On April 5, 2021, at 1700 central daylight time, a Robinson R44 helicopter, N8348X, was substantially damaged when it was involved in an accident near Johnson, Kansas. The pilot and one passenger were not injured. The helicopter was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to statements provided by the pilot and pilot-rated passenger, they were using the helicopter to check their wheat fields. The wind was from the south at 10 knots. The pilot executed a hover maneuver close to the ground and experienced a sudden unanticipated yaw to the left. The helicopter completed more than one full rotation to the left, then landed hard in the field and rolled onto its left side. The pilot reported that he was not aware of any mechanical malfunctions with the helicopter. The responding Federal Aviation Administration inspector reported that the helicopter sustained substantial damage to the fuselage and main rotor blades. Examination of the helicopter and flight control system did not reveal any preimpact mechanical malfunctions or anomalies that would have precluded normal operation. The helicopter manufacturer had previously issued a safety notice for unanticipated yaw, which stated in part: A pilot's failure to apply proper pedal inputs in response to strong or gusty winds during hover or low-speed flight may result in an unanticipated yaw…To avoid unanticipated yaw, pilots should be aware of conditions (a left crosswind, for example) that may require large or rapid pedal inputs.
