## Probable cause

The failure of the landing gear hydraulic drive motor.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Airframe/component/system failure/malfunction, approach
  - hydraulic system,motor - failure (cause)
- Gear collapsed, landing - roll

## Analysis

During the landing roll of a full-stop landing, all three of the aircraft's gear collapsed.  It was later determined that the hydraulic pump drive motor had failed during the extension process.  Although all three green gear-down indicator lights illuminated when the gear was extended, without the pump continuing to operate during the entire extension process, the gear did not reach the full down position, and the gear down-locks were not activated.

## Factual narrative

On August 30, 1995, approximately 1600 Pacific daylight time, a Cessna 210, N5349A, experienced a collapse of all three gear during the landing roll at Sunriver, Oregon. The commercial pilot, who was the sole occupant, was not injured, but the aircraft sustained substantial damage. The personal pleasure flight, which departed the same airport earlier that evening, was being operated in visual meteorological conditions at the time of the accident. No flight plan had been filed, and there was no report of an ELT activation.

According to the FAA inspector who responded to the accident, the aircraft was on the landing roll for a full-stop landing when all three gear collapsed. As the gear collapsed, the aircraft settled to the runway, and the horizontal stabilizer sustained substantial damage. When interviewed by the FAA, the pilot said that at the time of the touchdown all three gear down indication lights were green.

It was later determined that during the gear extension process, the hydraulic pump motor had failed. Without the pump continuing to work during the entire extension process, the gear is not forced into the full down position, and the down-lock pins are not activated.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

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.
