Substantial

Defining Event:

Hard landing

Flight Conducted Under:

Part 137: Agricultural

Analysis 

The helicopter pilot reported that, while conducting an agricultural application flight, he planned to fly over the top of a power pole. He applied full-up collective to climb over the pole, but the helicopter struggled to gain altitude. He added that, after the helicopter cleared the pole, the main rotor speed reduced and the helicopter "quit flying," so he decided to conduct a run-on landing on the field. The helicopter landed hard, and the main rotor blades struck the tailboom. The helicopter sustained substantial damage to the tailboom. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to maintain a proper descent rate, which resulted in a hard landing and the main rotor blades striking the tailboom.
