Investigation Docket - National Transportation Safety Board:
Location: Oshkosh, Wisconsin
Accident Number: CEN21LA344
Date and Time: July 30, 2021, 10:00 Local
Registration: N725DW
Aircraft: WEISS DENIS SPARROW II
Aircraft Damage: Substantial
Defining Event: Abnormal runway contact
Injuries: 2 Minor
Flight Conducted Under: Part 91: General aviation - Personal
Analysis
The pilot reported that during landing on a grass runway, the airplane first bounced about 5 ft high, then bounced a few more times as it neared the end of the runway. The pilot added that he did not have enough remaining runway to complete a go-around, so he applied the brakes, but they did not work. The airplane continued off the end of the runway and impacted a small ditch and sustained substantial damage to the fuselage and engine mount. A post-accident examination of the brake system revealed no mechanical malfunctions or anomalies 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 improper landing flare which resulted in a bounced landing, a loss of control, and runway excursion.
Findings
Aircraft Airspeed - Not attained/maintained
