Location: Red Wing, Minnesota
Accident Number: CEN20CA250
Date & Time: June 25, 2020, 15:00 Local
Registration: N35JA
Aircraft: Hatz HATZ CB 1
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact 
Injuries: 1 None
Flight Conducted Under: Part 91: General aviation - Personal

Analysis

The commercial pilot was practicing landings with light wind present in his tailwheel airplane on an occasionally used grass area south of the paved runway. The pilot made one successful landing on the grass. During the next landing, the airplane bounced, which resulted in a nose up attitude. The pilot does not recall if he added engine power to remedy the bounced landing. However, the pilot did not perform a go-around as recommended by the Federal Aviation Administration Airplane Flying Handbook. The airplane stalled and impacted terrain in a nose low attitude. The propeller "dug in" the terrain and the airplane nosed over. The airplane subsequently sustained substantial empennage damage. The pilot indicated that there were no mechanical malfunctions with the airplane.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to perform a go around following a bounced landing that resulted in an aerodynamic stall.

Findings
