## Probable cause

The pilot's loss of helicopter control on approach to land due to entering a vortex ring state condition, 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); cases with it: [Eurocopter EC 130 B4, 5 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=8680989), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md)
- [Approach: Settling with power/vortex ring state](https://openairdocs.org/ntsb-events/244) (defining event); cases with it: [Eurocopter EC 130 B4, 3 cases](https://openairdocs.org/ntsb-events/244/sequence.md?model=8680989), [All aircraft, 52 cases](https://openairdocs.org/ntsb-events/244/sequence.md)

## Analysis

The pilot in the helicopter reported that, he turned final approach at about 100 ft above ground level and the helicopter started settling with power [entered vortex ring state]. The pilot attempted to stop the descent by applying collective and forward cyclic, but the helicopter subsequently landed hard and sustained substantial damage to the aft fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
