N8897F

On June 01, 2010, a Hughes 269A (N8897F) was involved in an incident near Cannon Falls, MN. All 1 person aboard were uninjured. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's failure to maintain rotor speed during the autorotation, which resulted in an excessive sink rate and a hard landing.

The pilot reported that shortly after liftoff he noticed a “disturbing vibration” in the helicopter. He initiated an autorotation to an open agricultural field. The pilot stated that he executed a 180-degree turn in order to avoid a tree line. He noted that the rotor speed got too low and he was unable to reduce the sink rate, which resulted in a hard landing. The main rotor contacted and separated the tail boom, and the right landing skid collapsed during the accident sequence. The pilot noted that additional practice in autorotation descents and landings might have prevented the accident.

This incident is documented in NTSB report CEN10CA280. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N8897F.
