## Probable cause

The pilot’s improper landing flare which resulted in a hard landing. Contributing to the accident was the pilot’s failure to follow the checklist to remove the wing wheel and tail dolly before takeoff.

## 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.

## Analysis

The pilot of the powered glider reported that, after takeoff he realized that both the left wing and tail dolly were still attached. The pilot returned to the airport and prepared for a straight in landing to the grass runway with the electric propellor off and the main wheel retracted. The fuselage was substantially damaged when the glider landed hard. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.
