## Sequence of events

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

- On ground/water collision with object, takeoff - roll/run
  - preflight planning/preparation - improper, pilot in command (cause)
  - object - aircraft parked/standing
  - clearance - misjudged, pilot in command (cause)

## Analysis

DURING THE TAKEOFF ROLL THE GLIDER'S RIGHT WING COLLIDED WITH THE LEFT TIRE OF A PARKED AIRCRAFT. THE PILOT STATED THAT THE ACCIDENT COULD HAVE BEEN PREVENTED BY PULLING THE GLIDER OUT FARTHER.
