Narrative:
Aircraft ground looped while attempting a touch and go to runway 27. Wind instruments in the tower indicated 290 degrees at 09 KTS. Subsequent investigation appears to show the wind direction indicators were set in a test mode. A review of the archive received from the on-field WX observer indicated the wind to be 030 degrees at 11 KTS at the time of the incident.
