NTSB narrative
The newly certificated private pilot was cleared for a touch and go. The controller then stated '...make this a full stop I'll call your departure roll.' The pilot stated he did not understand what the controller meant, but he did not question the clearance. He stated he intended on making a full stop and turning off onto the taxiway. When nearing the end of the runway the controller cleared the pilot for takeoff. The pilot applied power then realized he did not have sufficient runway remaining for a takeoff. He reduced power, but the airplane continued off the end of the runway where it contacted a hole in the terrain. The ATC Handbook states the phraseology 'stop-and-go' should be used for spacing and sequencing traffic.
Probable cause
the pilot's improper decision to initiate the takeoff with insufficient runway remaining. A factor associated with the accident was pilot's failure to obtain clarification from the controller regarding the clearance.

- 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. 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.
