AN EXAM OF THE WRECKAGE REVEALED NO PREIMPACT PART FAILURE OR MALFUNCTION. THE PLT HAD APRX 40 HRS OF FIXED WING FLT TRAINING ABOUT 9 YRS PREVIOUSLY. ACCORDING TO THE CHIEF PLT FOR MITCHELL ACFT, THE PLT HAD COMPLETED A 1 WEEK GROUND SCHOOL COURSE & HAD 5.3 HRS OF DUAL INSTRUCTION IN A 2 PLACE VERSION OF THE ULTRALIGHT.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1983-07-11.
  • API snapshot SHA-256: 409c451ff7f5632273a8ecc6ae1dbd7e206e6c269094aa1f937452f8c7d8b651; retrieved 2026-09-21T06:30:29.689Z.
