## Probable cause

The flightcrew's misjudged flare while 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: [Fairchild SA227-AC, 1 case](https://openairdocs.org/ntsb-findings/01062041/cases.md?model=3377509), [All aircraft, 1,285 cases](https://openairdocs.org/ntsb-findings/01062041/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: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [Fairchild SA227-AC, 2 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=3377509), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)

## Analysis

According to the operator's director of operations, maintenance personnel discovered damage to the twin-engine turboprop airplane during a routine, daily inspection.  A review of the airplane flight logs revealed that the airplane's damage most likely occurred as the result of a hard landing event during the last flight, earlier that day. The airplane sustained structural damage to the wings and fuselage.  Neither of the two pilots reported any preaccident mechanical problems with the airplane, nor did they report any hard landing event.

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.
