## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - proper descent rate - not maintained, pilot in command (cause)
  - flare - improper, pilot in command (cause)
- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll
  - object - fence (contributing factor)

## Analysis

THE PILOT SAID HE ENCOUNTERED A HIGH SINK RATE DURING THE APPROACH. DIRECTIONAL CONTROL WAS LOST AFTER THE PILOT FAILED TO ARREST THE SINK RATE AND MADE A HARD LANDING. THE ACFT LEFT THE RUNWAY AND COLLIDED WITH A FENCE BEFORE COMING TO REST.
