## Probable cause

The pilot's inadequate flare, which resulted in a 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: [Beech 58, 4 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md?model=1152740), [All aircraft, 1,285 cases](https://openairdocs.org/ntsb-findings/01062041/cases.md)
- [Action: incorrect action performance](https://openairdocs.org/ntsb-findings/02041015): Personnel issues › Action/decision · Pilot (probable cause); cases with it: [Beech 58, 3 cases](https://openairdocs.org/ntsb-findings/02041015/cases.md?model=1152740), [All aircraft, 1,386 cases](https://openairdocs.org/ntsb-findings/02041015/cases.md)

## Sequence of events

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

- [Landing: Loss of control in flight](https://openairdocs.org/ntsb-events/240) (defining event); cases with it: [Beech 58, 14 cases](https://openairdocs.org/ntsb-events/240/sequence.md?model=1152740), [All aircraft, 5,002 cases](https://openairdocs.org/ntsb-events/240/sequence.md)
- [Landing: Hard landing](https://openairdocs.org/ntsb-events/092); cases with it: [Beech 58, 4 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=1152740), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

The pilot stated that during the landing, he misjudged the airplane's height above the runway. He flared the airplane too soon and it touched down hard. The airplane slid down the runway and came to rest upright. During the accident sequence, the airplane sustained damage to the fuselage and both wings. The pilot reported no preimpact mechanical anomalies with the airplane.
