During landing on runway 34, a 3,313 foot-long and 75-foot wide asphalt runway, the pilot of the Beech A36 airplane encountered a wind gust, which he estimated to be about 40 knots. The airplane then bounced on the runway and the landing gear collapsed, substantially damaging the right wing. The wind reported at the ai...

Files

  • data/: the train, val, and test splits used for finetuning and inference
  • raw.jsonl: every cleaned record with its narrative, reference fields, and split, used as evaluation ground truth
  • preparation_config.yaml: the exact cleaning, splitting, and prompt configuration used
  • vocab_schema.json: the closed vocabulary for every categorical field, as a JSON Schema

Processing

  • Combined source splits: train
  • Document length: 300 to 30,000 characters
  • Deduplicated by document hash and split deterministically with seed 42
  • Rows whose target fields fail schema validation are dropped during cleaning

Splits

  • train: 9,172 records
  • val: 500 records
  • test: 600 records

Schema

Each record contains a stable id and messages with system, user, and assistant turns. The assistant turn contains the reference occurrence sequence, injury/damage/purpose-of-flight fields, and primary finding as JSON (see NtsbExtractionFields).
