On October 25, 1993, at approximately 1600 central daylight time, N94BG, a Burkhart Grob Flugzeugbau G103, impacted terrain during landing approach to Boerne Stage Field, San Antonio, Texas. The two pilots aboard were not injured, but the aircraft sustained substantial damage. Visual meteorological conditions prevailed at the time, and no flight plan was filed for the personal flight. The pilot said he was "unfamiliar with the territory and ran out of airspace. Upon landing, pilot noted altimeter was set wrong." According to an inspector from the Federal Aviation Administration, the pilot told him he was banking right from base leg to final approach. He said he should have been looking outside, but instead was watching the altimeter. He thought he was 40 feet above the ground when he made the turn. His attention was directed outside the aircraft when he felt the nose and right wing striking the ground.
