NTSB narrative
On May 15, 2025, about 1339 eastern daylight time, a Grumman TBM-3 airplane, N420GP, was substantially damaged when it was involved in an accident near Terre Haute, Indiana. The pilot sustained serious injuries, and the pilot-rated passenger sustained minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 positioning flight. The pilot reported that while on final approach to the runway, he attempted to increase engine power, but the engine did not respond. He began troubleshooting by switching fuel tanks and completing the emergency checklist item; however, engine power was not restored. The pilot executed a forced landing, and the airplane touched down on the airport perimeter road. The airplane then impacted a drainage ditch, struck the airport perimeter fence, and came to rest inverted. The airplane sustained substantial damage to both wings, fuselage and empennage. The airplane was recovered to a secure facility for further examination.

- 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: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
