NTSB narrative
The multiengine student and flight instructor were on approach to land and were advised of traffic in the pattern. The instructor was handling the communications and advised they would do 'S' turns for spacing. While looking for traffic and maneuvering for spacing, the student pilot inadvertently turned the right fuel selector off during the prelanding checklist. As they were lining up on final approach and after an 'S' turn, a loss of power in one engine became apparent The instructor took control of the airplane and started engine-out procedures. During that time they collided with terrain. After the accident, the pilots examined the cockpit and found that the right fuel selector was in the off position.
Probable cause
a loss of power in one engine due to the student pilot inadvertently selecting the off position on one fuel selector valve while accomplishing the prelanding checklist. The instructor's inadequate supervision of the flight was also causal.

- 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.
