## Probable cause

FAILURE OF THE RIGHT BRAKE LINE AT THE CALIPER DURING THE LANDING ROLL RENDERING THE BRAKES INEFFECTIVE. A FACTOR WAS THE PILOT'S MISJUDGEMENT OF WIND DIRECTION.

## 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 - failure,partial (cause)
  - brakes(normal) - not possible, pilot in command (cause)
- Overrun, landing - roll
  - wind information - misjudged, pilot in command (contributing factor)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ditch
- Nose gear collapsed, landing - roll
- Nose over, landing - roll

## Analysis

THE PLT STATED HE OVERFLEW THE PVT ARPT & LOOKED AT AN ADJACENT LAKE FOR INDICATION OF WIND DIRECTION & VELOCITY, BUT STATED THE WIND APPEARED TO BE LIGHT.  HE ELECTED TO LAND TO THE NORTH & AFTER TOUCHDOWN HE APPLIED THE BRAKES BUT THE RT BRAKE LINE FAILED AT THE BRAKE CALIPER.  THE ACFT TRAVELLED OFF THE END OF THE RWY, ACROSS A ROAD, AND NOSED OVER AFTER TRAVELLING DOWN A DITCH EMBANKMENT WHICH COLLAPSED THE NOSE LANDING GEAR. ACCORDING TO A SHERIFF DEPUTY WHO RESPONDED TO THE ACCIDENT SITE, THE PLT LANDED WITH A 15 KT TAILWIND.  THE PLT FURTHER STATED THAT THERE IS NO WINDSOCK AT THE ARPT.
