Analysis

The newly rated prt plt was on his 12th flt in the recently certificated homebuilt that he had designed and built himself. While performing an unknown maneuver both horizontal stabilizers and both wings separated from the acft. The acft was restricted from performing aerobatics however, an acft log the plt kept reflected that he had flown the acft in a steep dive recovering at 140 mph. The acft was redlined at 103 moh. He had also logged that hammer heads and wing overs were performed by himself in this acft.
