NTSB narrative
Upon return to the airport after a local flight, the pilot-in-command ascertained that the single north/south runway was closed. He then initiated an approach to the 50-foot wide asphalt parallel taxiway which had been NOTAM'ed by airport management as the alternate landing runway during runway closure. The pilot touched down short of the 1,200 foot displaced threshold of the landing taxiway and rolled over a hump during which the aircraft bounced. The pilot then lost directional control and the aircraft rolled off the taxiway into a drainage ditch alongside the taxiway, coming to rest in a nose-over attitude. The displacement to the taxiway threshold (upwind of the hump) was reported by the FBO to consist of plywood which had not been painted in a conspicuous color and was placed in the grass alongside the taxiway at the intended displacement location.
Probable cause
The pilot-in-command's failure to maintain directional control. Contributing factors were the uneven taxiway, inadequate airport maintenance (temporary threshold marking) by the airport management, and a ditch alongside the taxiway.

Source notes (4)
- 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.
