NTSB narrative
The pilot reported that, while making a straight-in approach to a private airport just after dusk, but before dark, he attempted to activate the pilot-controlled lighting (PCL) but was unsuccessful. He added that he continued toward the airport, and while maneuvering for landing, he lost sight of the airport. The pilot did not regain visual reference of the airport during the landing descent, and the airplane impacted a fence adjacent to the runway.
The airplane sustained substantial damage to the fuselage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The airport owner reported that the PCL antenna required line-of-sight with the aircraft to operate the PCL system. Due to the antenna's position and hangars on the airport, the antenna did not receive signals from the southeast, the direction from which the accident airplane was approaching. He added that, because the airport was private, he could not issue a NOTAM to describe the operation of the runway lights.
Probable cause
The pilot’s decision to continue to land without visual reference to the airport in low light conditions. Contributing to the accident was the pilot’s inability to activate the private airport’s pilot-controlled lighting system due to its configuration.

- 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.
