Analysis 

The flight instructor in the weight shift aircraft, which was equipped with a floor mounted, foot operated throttle, reported that upon startup, the pilot receiving instruction inadvertently applied full throttle while putting his right foot on the pedal power control unit. Subsequently, the weight shift aircraft started to move towards a parked jet, so the flight instructor turned the aircraft sharply and the aircraft tipped onto its side.

The weight shift aircraft sustained substantial damage to both wings.

The flight instructor reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine 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 receiving instruction's inadvertent application of throttle during the engine start, which led to an inadvertent acceleration and a roll-over.
