Aviation Accident Data Summary - National Transportation Safety Board: 

Location: Clayton, GA
Accident Number: GAA18CA458
Date & Time: 07/30/2018, 1330 EDT
Registration: N608US
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal


The powered-glider pilot reported that, during the approach, about 10 to 20 ft above the ground, the descent rate was higher than normal. He moved his hand from the spoiler to the throttle, but before he could apply power to arrest the descent, the glider landed hard and bounced. The glider then banked left, he added full power, but the left wingtip impacted a hedge, and the glider rotated counterclockwise. Subsequently, the glider impacted the ground and came to rest on a dirt embankment.

The powered-glider sustained substantial damage to the fuselage, empennage, and engine mount.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider 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, bounced landing and runway overrun.


Descent rate - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
