## Probable cause

The pilot's loss of directional control while landing, which resulted in a runway excursion.

## Findings

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

- [Performance/control parameters: directional control](https://openairdocs.org/ntsb-findings/01062020): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause); cases with it: [Diamond Aircraft Ind DA 40, 11 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md?model=2990002), [All aircraft, 3,969 cases](https://openairdocs.org/ntsb-findings/01062020/cases.md)
- [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause); cases with it: [Diamond Aircraft Ind DA 40, 20 cases](https://openairdocs.org/ntsb-findings/02063040/cases.md?model=2990002), [All aircraft, 9,308 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: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Diamond Aircraft Ind DA 40, 12 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=2990002), [All aircraft, 4,590 cases](https://openairdocs.org/ntsb-events/230/sequence.md)
- [Landing-aborted after touchdown: Runway excursion](https://openairdocs.org/ntsb-events/300); cases with it: [Diamond Aircraft Ind DA 40, 9 cases](https://openairdocs.org/ntsb-events/300/sequence.md?model=2990002), [All aircraft, 3,656 cases](https://openairdocs.org/ntsb-events/300/sequence.md)

## Analysis

The student pilot was performing a supervised solo flight in the airport traffic pattern as the flight instructor observed from the ground. During landing, upon touching down on the runway, the airplane bounced and started drifting to the left. The pilot attempted to correct, but the airplane continued to veer to the left. He added power in an attempt to abort the landing, but the airplane struck a taxiway sign and then “cartwheeled” before impacting a security fence off the side of the runway. The airplane sustained substantial damage to the fuselage and wings. The flight instructor reported that there were no preimpact mechanical malfunctions or failures of the airplane 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.
