## 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
  - airspeed - misjudged, pilot in command (cause)
  - distance - misjudged, pilot in command (cause)
  - recovery from bounced landing - improper, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - ground loop/swerve - inadvertent, pilot in command (contributing factor)
- On ground/water collision with object, landing - roll

## Analysis

THE PILOT STATED THAT HIS APPROACH WAS TOO FAST AND HE BOUNCED THE ACFT DURING THE LANDING. THE GLIDER DRIFTED LEFT AND COLLIDED WITH A HAYROLL. THE COLLISION CAUSED ANOTHER SWERVE AND A SUBSEQUENT COLLISION WITH ANOTHER HAYROLL.
