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

  - preflight planning/preparation - poor, pilot in command (cause)
  - airport facilities,runway/landing area condition - snow covered (contributing factor)
  - airport facilities,runway/landing area condition - icy (contributing factor)
  - aborted takeoff - not performed, pilot in command (contributing factor)
  - object - tree(s) (cause)
  - ground loop/swerve - uncontrolled, pilot in command (cause)

## Analysis

THE WHEEL EQUIPPED ACFT BROKE THROUGH THE ICE DURING A TAKEOFF FROM A FROZEN LAKE. THE INCREASED DRAG SLOWED THE ACFT AND THE PLT WAS ABLE TO CLEAR SOME TREES BUT AFTER BOUNCING ALONG FOR 300-400 FT THE ACFT HIT A TREE AND GROUND LOOPED. THE ACFT WRECKAGE WAS REMOVED BEFORE THE INVESTIGATION STARTED.

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.
