## Probable cause

THE FAILURE OF THE HYDRAULIC LINE WHICH RENDERED THE BRAKE SYSTEM INOPERATIVE.

## Sequence of events

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

- Airframe/component/system failure/malfunction, landing - roll
  - landing gear,normal brake system - inoperative (cause)
  - hydraulic system,line - failure,total (cause)
  - brakes(normal) - not possible, pilot in command (contributing factor)
- Loss of control - on ground/water, landing - roll
- Nose over, landing - roll
  - terrain condition - open field

## Analysis

THE PILOT SAID THAT HE WAS RETURNING TO A PRIVATE LDG STRIP AFTER COMPLETING AN AERIAL APPLICATION OPERATION. DURING THE LANDING ROLL, THE LEFT BRAKE LINE FAILED CAUSING THE ACFT TO VEER OFF THE RUNWAY AND OVERTURN.

## FAA reports on this event (1)

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

- [Accident 19890301002859A](https://openairdocs.org/incident/19890301002859A), Mar 1, 1989: Scwzer G164B, Harrisburg, AR, Substantial damage. Left brake line failed on landing roll. Veered off runway and overturned.

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.
