## Probable cause

The pilot's improper flare, which resulted in a loss of aircraft control and hard landing.

## Findings

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

- [Performance/control parameters: landing flare](https://openairdocs.org/ntsb-findings/01062041): Aircraft › Aircraft oper/perf/capability · Incorrect use/operation (probable cause); cases with it: [Xiru Wang YUNEEC E-430, 1 case](https://openairdocs.org/ntsb-findings/01062041/cases.md?model=05632WC), [All aircraft, 1,285 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md)
- [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Xiru Wang YUNEEC E-430, 1 case](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=05632WC), [All aircraft, 9,295 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md)

## 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) (defining event); cases with it: [Xiru Wang YUNEEC E-430, 1 case](https://openairdocs.org/ntsb-events/090/sequence.md?model=05632WC), [All aircraft, 1,506 cases](https://openairdocs.org/ntsb-events/090/sequence.md)

## Analysis

The pilot reported that during approach to land he flared too high. The airplane subsequently landed hard, which collapsed the left main landing gear and nose gear, and substantially damaged the left wing. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

## Factual narrative

The pilot reported that during approach to land he flared too high. The airplane subsequently landed hard, which collapsed the left main landing gear and nose gear, and substantially damaged the left wing. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
