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 requires line-of-sight with the aircraft to operate the PCL system. Presently, due to the antenna's position and hangars on the airport, the antenna does not receive signals from the southeast, the direction from which the accident airplane was approaching. He added that, since the airport was private, he could not issue Notices to Airmen (NOTAMs) to describe the operation of the runway lights.
