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 owner/builder had a single engine, multi-engine, land rating, but did not have a helicopter rating. While practicing hover flt in his experimental helicopter, he unexpectedly allowed the helicopter to reach a higher than normal alt. He attempted to correct the situation, but the helicopter contacted the ground in a right bank attitude while in a side slip, then rolled over.
