Summary
On May 10, 2013, a Bell 206-L4 (N2036F) was involved in an incident near Fort Worth, TX. All 2 people aboard were uninjured. The aircraft sustained substantial damage.
The National Transportation Safety Board determined the probable cause of this incident to be: The flight instructor's inadequate supervision and delayed remedial action during a practice autorotation, which resulted in a hard landing.
The pilot receiving instruction was conducting a practice right 180 degree autorotation. During the approach, the airspeed decreased to approximately 40 knots which shortened the approach angle. At 8 to 10 feet above the ground, the flight instructor advised the pilot to apply forward cyclic while maintaining the collective position. The flight instructor then "used what was left of the rotor RPM to cushion the landing." During the touchdown, the helicopter landed hard, which resulted in structural damage to the tailboom. The pilot reported no preimpact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
This incident is documented in NTSB report CEN13CA276. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N2036F.
