Registration: N4163B
Aircraft:  HARROP BLAKE RV 7
Aircraft Damage: Substantial
Defining Event: Aerodynamic stall/spin
Injuries: 2 Minor
Flight Conducted Under: Part 91: General Aviation - Personal 

Analysis 

The pilot reported that, during the landing flare, about 2 to 3 ft above the ground, he reduced power, and the airplane aerodynamically stalled. The airplane landed hard and then bounced, the nose landing gear collapsed, and the airplane then came to rest inverted.

The airplane sustained substantial damage to the canopy and empennage.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane 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 adequate airspeed and his exceedance of the airplane's critical angle of attack during the landing flare, which resulted in an aerodynamic stall.

Findings

Aircraft
Angle of attack - Capability exceeded (Cause)
Airspeed - Not attained/maintained (Cause)

Personnel issues
Aircraft control - Pilot (Cause)
