NTSB narrative
The pilot stated that he took off on runway 17, established a climb, and retracted the landing gear. He said that the engine then started running rough, and he had used up about half of the runway, and was too high for a normal flap landing, so he executed a "sharp" slip to the left. He said he then dropped the landing gear, but the airplane touched down before the landing gear locked. The airplane slid along the runway and veered to the right, impacting a VASI light, incurring damage. A postcrash examination of the accident airplane was performed by an FAA licensed airframe and powerplant mechanic, with an inspection authorization rating, and the examination revealed no anomalies.
Probable cause
A reported loss of engine power shortly after takeoff for undetermined reasons.

- 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.
