At 15:35 PDT, a Vans RV-6A dragged the left wing tip while turning from base to final for runway 20 at Sacramento Executive Airport. The two occupants were not injured. The pilot told investigators he had been cleared for a short approach in front of another airplane that was on a straight-in approach. He stated that as he turned from base to final over the runway, the left wing tip struck the pavement. The airplane then struck the runway, shearing off the nose gear and collapsing the main gear.
