## Probable cause

THE PILOT'S IMPROPER AIRCRAFT HANDLING.

## Sequence of events

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

- Overrun, landing - roll
  - aircraft handling - improper, pilot in command (cause)
- On ground/water collision with object, other
  - object - pole

## Analysis

DURING A DAYLIGHT LANDING TO AN IMPROVED RUNWAY, THE PRIVATE PILOT EXECUTED A RIGHT TURN AT HIGH SPEED RESULTING IN THE AIRPLANE SLIDING RIGHT AND A LOSS OF CONTROL. THE AIRPLANE STRUCK THREE METAL PIPES AND A CHAIN LINK FENCE. THE PILOT EXECUTED THE RIGHT TURN WHEN SHE BECAME AWARE THAT SHE WOULD NOT BE ABLE TO STOP ON THE REMAINING RUNWAY. THE PILOT REPORTED A LOSS OF BRAKING EFFECTIVENESS; HOWEVER, INSPECTION OF THE BRAKES REVEALED NO MALFUNCTION.
