Full Narrative
On July 22, 2025, about 1400 central daylight time, a Robinson Helicopter Company R66 helicopter, N88911, was substantially damaged when it was involved in an accident near Maynard, Iowa. The pilot was uninjured. The helicopter was operated under Title 14 Code of Federal Regulations as a Part 137 aerial application flight.
The pilot stated that he had been conducting spray operations for about 50 minutes. The helicopter was about 5 to 10 ft above the corn when, during a turn, the turbine engine flamed out. He stated that he immediately lowered the collective and applied aft cyclic to gain altitude. The pilot then executed a forced landing in the corn field, which resulted in the separation of the helicopter’s tailboom.
The helicopter was retained for further examination.
