Aircraft Accident/Incident Report

San Antonio, Texas 78216
Monday, July 18, 2011 12:15 CDT

NTSB Narrative Summary Released at Completion of Accident

During the pilot’s second landing attempt, the airplane touched down on the runway and began to porpoise. The pilot attempted to execute a go-around by applying full engine power; however, the airplane began to yaw left and descend. When the airplane started to bank “uncontrollably” to the left, the pilot executed a gear-up landing in the grass alongside the runway. An examination of the airplane following the accident did not reveal any preimpact anomalies.

NTSB Probable Cause Narrative

The pilot’s failure to maintain aircraft control during the go-around maneuver.
