## Probable cause

THE PILOT'S IMPROPER REMEDIAL ACTION TO REGAIN DIRECTIONAL CONTROL DURING THE LANDING.

## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - directional control - not maintained, pilot in command
  - remedial action - improper, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll
  - object - pole

## Analysis

THE ACCIDENT OCCURRED DURING THE MAIDEN FLIGHT IN THIS HOMEBUILT AIRCRAFT. THE PILOT MADE A LOCAL FLIGHT AND WAS ATTEMPTING TO LAND WHEN THE ACCIDENT OCCURRED. HE STATED THAT THE AIRSPEED WAS LITTLE HIGH DURING THE LANDING AND THE AIRCRAFT BOUNCED. DURING THE BOUNCE THE AIRCRAFT VEERED TO THE LEFT. THE PILOT APPLIED RIGHT RUDDER AND POWER AT WHICH TIME THE AIRCRAFT VEERED SHARPLY TO THE RIGHT AND TRAVELED OFF THE RIGHT SIDE OF THE RUNWAY AND CAME TO REST AFTER CONTACTING GUARD POSTS.
