The NTSB's narrative final · quoted from the NTSB record
During a familiarization flight with a flight instructor, the pilot-rated student landed the helicopter in tall grass approximately 50 feet short of the intended touchdown point. While attempting to take off with 'the right skid embedded in soft earth,' the helicopter 'rolled to the right and came to rest on its side.' The pilot-rated student held a German private pilot certificate with a helicopter rating.
