NTSB narrative
The pilot reported that, during landing, on short final, he "corrected the approach with a crab for a crosswind landing," and the airplane touched down on the first third of the runway "slightly fast" and left of the runway centerline. During the landing roll, the airplane gradually veered left and exited the runway. The pilot applied full power and initiated a go-around, but the airplane continued left and struck a power box.
The airplane sustained substantial damage to the right-wing lift strut and right horizontal stabilizer.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
An automated weather observation station located on an airport about 6 nautical miles away from the accident site reported that, about the time of the accident, the wind was variable at 4 knots. The pilot reported that the wind was from the north and between about 10 and 15 knots. The pilot landed the airplane on runway 28.
Probable cause
The pilot's failure to maintain directional control after landing left of the runway centerline, which resulted in a runway excursion and impact with a power box.

- 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.
