## Probable cause

THE PILOT'S FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING LANDING ROLL. A FACTOR WAS THE PATCHY ICE ON THE RUNWAY.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - directional control - not maintained, pilot in command (cause)
- Overrun, landing - roll
- On ground/water encounter with terrain/water, landing - roll

## Analysis

THE PILOT LOST DIRECTIONAL CONTROL WHILE LANDING ON A RUNWAY WITH PATCHY ICE AND POOR BRAKING ACTION.  THE AIRCRAFT SLID SIDEWAYS OFF THE END OF THE RUNWAY, IMPACTED A DIRT BERM, AND COLLAPSED THE NOSE LANDING GEAR.

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.
