Flight Conducted Under: Part 91: General Aviation - Instructional 

Analysis 

The flight instructor in the weight-shift-controlled aircraft reported that, during a demonstration flight, during the landing flare, he observed the wind sock shift 90°, and he felt a violent wind gust from the left that lifted the left wing. He attempted to lower the left wing, but the right wing impacted the ground, and the aircraft cartwheeled before coming to rest.

The flight instructor reported that, after the accident, an airport worker reported to him that he had been caught in a "dust devil."

The weight-shift-controlled aircraft sustained substantial damage to the left wing.

The flight instructor reported that there were no preaccident mechanical failures or malfunctions with the weight-shift-controlled aircraft that would have precluded normal operation.

The automated weather observation station located on the airport reported that, about 13 minutes after the accident, the wind was from 230° at 8 knots. The weight-shift-controlled aircraft landed on runway 25.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The flight instructor's failure to maintain lateral control of the weight-shift-controlled aircraft during the landing flare.

A light sport aircraft crashed near a runway at Hawthorne Municipal Airport Tuesday afternoon, but its pilot and one passenger were not seriously injured, officials said.

The crash occurred at 12:30 p.m. at the airport, said Gustavo Medina, an inspector with the Los Angeles County Fire Department. Paramedics evaluated the two people who were on board, but they declined transport to a hospital, he said.

Federal Aviation Administration spokesman Ian Gregor said the agency will investigate what caused the Revolution Revo to crash as it landed.

The Revolution Revo crashed just north of the runway in a “safety area,” and the passengers walked away, said Airport Supervisor Guido Fernandez.
