## Probable cause

The pilot’s improper landing flare which resulted in a hard 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: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [I.C.A.-Brasov IS-28B2, 1 case](https://openairdocs.org/ntsb-events/092/sequence.md?model=4490102), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

The pilot of the glider reported that, on a visual approach and landing he flared the nose too high. The tailwheel touched down first and the nose impacted hard, resulting in several firm oscillations. The glider sustained substantial damage to the wings and fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
