NTSB narrative
The pilot reported that, before the flight, he performed weight and balance and performance calculations with the initial fuel level in the airplane. The fuel tanks were then filled full of fuel, but he did not amend the weight and balance or performance calculations.
The pilot reported that, during takeoff, after the airplane became airborne, he did not feel comfortable with the way the airplane was performing, so he reduced power and landed the airplane on the remaining runway. He added that he did not have enough runway to stop and attempted to exit on a taxiway but "understeered," and the airplane exited the runway into a ditch.
The airplane sustained substantial damage to the fuselage.
The airplane's maximum gross weight was 2,460 lbs, and the weight at the time of the accident was 2,600 lbs, which was about 140 lbs over the maximum gross weight and likely affected the airplane's takeoff performance.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s decision to take off with the airplane over its maximum gross weight due to his failure to perform preflight weight and balance calculations, which affected the airplane’s takeoff performance, and his subsequent decision to abort the takeoff with too little runway remaining, which resulted in a runway excursion.

- 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.
