NTSB narrative
On May 30, 2026, about 0900 Pacific daylight time, an Air Tractor AT-602, N5111A, was substantially damaged when it was involved in an accident near Robbins, California. The pilot sustained minor injuries. The airplane was operated as a Title 14 Code of Federal Regulations Part 137 Agricultural Aircraft Operations.
The pilot reported that he was on an aerial seeding flight and that about 45 minutes after refueling he maneuvered toward a private airstrip to replenish his load. He added that the engine lost all power during a brief climb prior to landing at the airstrip when he was about 300 feet above ground level. After the pilot heard the engine spool down, the airplane started to sink. Subsequently, the pilot configured the airplane for best glide and executed a forced landing in a paddy field. The airplane nosed over shortly after touchdown and came to rest inverted, which resulted in substantial damage to the empennage.
The airplane and engine were 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.
