Most small aircraft accidents are completely preventable loss of control (either by taking off with too much weight, stalling during takeoff, or stalling during landing) or flying into IMC (instrument metereological conditions including clouds, fog, etc.) and becoming disoriented and losing control. Simple engine failure is something that every private pilot trains for. Improvements in training can significantly help with both. Instrument training in particular drastically reduces the risks of inadvertent IMC. Some technology also assists with the latter (eg; synthetic vision on foreflight on aircraft with garmin G1000 cockpits gives you references for how the plane is positioned and any terrain around you you could hit).
