NTSB narrative
The flight instructor reported that during the student pilot's first night flight, the lesson was to familiarize the student with flying at night, and included takeoffs and landings. The flight instructor reported that during landing, the student pilot held the approach path "for a while" then drifted below the approach path, as indicated by the visual approach slope indicator. The flight instructor told the student that he needed to climb and reestablish the airplane on the approach path.
The flight instructor reported that subsequently he (the instructor) "became confused" and could not determine the airplane's position relative to the runway. The flight instructor reported that he "snapped out of the condition", but the airplane collided with trees and impacted the ground short of the runway before a recovery could be made. The airplane sustained substantial damage to the left wing.
The pilot reported no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
Probable cause
The student pilot's descent below the prescribed final approach path at night, and flight instructor's failure to correct the student pilot's descent, which resulted in a collision with trees and impact with the ground.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2015-12-11.
