Approximate · Coordinates corrected after review: The narrative places the nose-over in a wheat field just past the end of the departure runway at Watsonville ("The airplane was over the end of the runway"); the recorded latitude 35.93 is in the Pacific Ocean off Big Sur, and 36.93 at the same longitude is Watsonville airport (a one-digit error). No uncertainty radius is established.
NTSB narrative
The airplane nosed over in a wheat field following a loss of engine power during takeoff. The certified flight instructor (CFI) estimated that 10 to 15 minutes elapsed between completion of the run-up and takeoff checklist before traffic cleared so that he and the student could take off. The takeoff was normal, and they started their climb to the practice area. About 200 to 300 feet agl, the engine started to lose power; it didn't just lose power. He took control. He applied carburetor heat, and pumped the throttle a few times as he had done in the past to keep an engine running. However, the engine didn't respond. The airplane was over the end of the runway. He felt that they were too low to turn around, and wanted to get the airplane down before they flew past the clear area before a freeway. He aimed for a wheat field that he thought would cushion the landing. He estimated that about 40 seconds elapsed from the loss of power to touchdown. The wheat in the field was 4-feet tall, and a lot thicker than the CFI expected. It stopped the airplane on touchdown, causing a nose over. He saw fire in the engine compartment. He instructed the student to be careful unstrapping since they were inverted, but to hurry. They both exited out the right side door, and cleared the airplane. The FAA coordinator examined the airplane and engine and no abnormalities were found to preclude normal operation.
Probable cause
a partial loss of engine power for undertermined reasons during takeoff.

Source notes (5)
- 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.
- API snapshot SHA-256: 3fbeecd09b1c4cc5994b736ae9dfbb1d555d95c0b36a65ccda9d7f3117e40938; retrieved 2026-09-21T18:31:57.419Z.
- Corrected after a review of the NTSB narrative, which states these values explicitly: coordinates. The narrative places the nose-over in a wheat field just past the end of the departure runway at Watsonville ("The airplane was over the end of the runway"); the recorded latitude 35.93 is in the Pacific Ocean off Big Sur, and 36.93 at the same longitude is Watsonville airport (a one-digit error).
