Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The acft was taking off on a test flt to determine the aft c.g. limits in conjunction with an STC modification. As the acft was lifted off in a front skids high attitude, it entered an uncommanded right roll. Full left cyclic would not stop the roll and the acft rolled over. Gusty winds and mechanical turbulence from nearby bldg's contributed to the dynamic rollover.
