## Probable cause

The pilot's inadequate flare, which resulted in a bounced landing and subsequent loss of aircraft control during landing.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

- [Landing-flare/touchdown: Abnormal runway contact](https://openairdocs.org/ntsb-events/090); cases with it: [Bayer Oscar STARDUSTER SA300, 1 case](https://openairdocs.org/ntsb-events/090/sequence.md?model=86603AG), [All aircraft, 1,506 cases](https://openairdocs.org/ntsb-events/090/sequence.md)
- [Landing-flare/touchdown: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Bayer Oscar STARDUSTER SA300, 1 case](https://openairdocs.org/ntsb-events/230/sequence.md?model=86603AG), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md)

## Analysis

The pilot reported that during touchdown in the tailwheel equipped airplane, it bounced once, and as the airplane main landing gear made contact with the runway, the right landing gear strut collapsed. The pilot lost directional control and the airplane ground looped. The fuselage and right wing sustained substantial damaged. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
