Investigator assessment
Analysis narrative
The pilot reported that, while practicing stop-and-go landings, the airplane touched down and began drifting to the left. Subsequently, the pilot attempted a go-around. However, as he added full power, the airplane’s drift worsened. The left wing contacted a runway hold short sign and the airplane departed the runway which resulted in substantial damage to both wings and the horizontal stabilizer. The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
