NTSB narrative
The student pilot had landed the airplane, exited the runway and was taxiing to parking. The tower controller informed the pilot that a helicopter was above him and to his right. The pilot looked to the right and saw the helicopter. While watching the helicopter, the pilot added right brake and throttle to move the airplane towards the center line of the taxiway. As the airplane turned, the pilot felt a jolt and saw that the airplane's left wing had contacted a utility trailer, substantially damaging the wing spar. The pilot stated that the accident could have been prevented if he had looked to all sides before turning and not allowed himself to be distracted by the presence of the helicopter.
Probable cause
The pilot's failure to maintain clearance while taxiing. Contributing to the accident was the pilot's diverted attention.

- 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.
