BELL 47GS/N: 7952

Summary

On July 31, 2011, a Bell 47G (N6260C) was involved in an incident near Porterville, CA. 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 decision to takeoff in a tailwind condition, and his subsequent failure to attain sufficient lift during the takeoff.

The pilot reported that during the agricultural operation he landed the helicopter into the wind to reload with fuel and agricultural chemicals. While the loader was mixing the chemicals, the pilot noted that the wind shifted to a tailwind condition. The pilot also noted that the rotor blades were dirty, but he forgot to clean them before departure. During the takeoff, the helicopter was unable to gain any lift and it started to sink back to the ground. The helicopter impacted the ground moments after takeoff with a slight nose low attitude which resulted in the skids collapsing and the main rotor blades contacting the tailboom. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation.

This incident is documented in NTSB report WPR11CA394. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N6260C.
