## Probable cause

FAILURE TO MAINTAIN DIRECTIONAL CONTROL BY THE PILOT. FACTORS RELATED TO THE ACCIDENT ARE LACK OF TOTAL EXPERIENCE IN TYPE AIRCRAFT, AND TYPE OF OPERATION.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - directional control - not maintained, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
  - lack of total experience in type operation, pilot in command (contributing factor)
- On ground/water collision with object, takeoff - aborted
  - object - aircraft parked/standing

## Analysis

STUDENT PILOT ON OBSERVED SOLO IN GLIDER HAD DIFFICULTY MAINTAINING DIRECTIONAL CONTROL DURING TAKEOFF TOW BEFORE BECOMING AIRBORNE, AND RELEASED TOWLINE. GLIDER DEPARTED RIGHT SIDE OF RUNWAY AND HIT ANOTHER GLIDER PARKED ALONGSIDE THE RUNWAY.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
