On February 12, 2001, about 1640 eastern standard time, a Robinson R22 Beta, N2327S, registered to an individual, crashed while maneuvering near Parkland, Florida, while on a Title 14 CFR Part 91 instructional flight. Visual meteorological conditions prevailed at the time and no flight plan was filed. The helicopter received substantial damage and the commercial-rated flight instructor and student pilot were not injured. The flight originated from Fort Lauderdale, Florida, the same day, about 1550. The flight instructor stated that after departure from Fort Lauderdale Executive Airport,, they flew to the practice area northwest of the airport. After practicing hovering for about 35 minutes, they practiced a traffic pattern, to breakup the lesson. After performing the traffic pattern, they returned to practicing hovering. About 5 minutes later, while hovering, the student was flying the helicopter. The helicopter was drifting to the left and the student let the helicopter settle from about 5 feet. The instructor stayed light on the controls and waited for the student to correct the altitude. He told the student to raise the collective and apply some right cyclic. The student failed to correct and as the instructor began to make the corrections, the left skid skipped off of the ground. This put the helicopter into a rolling motion to the left. He applied collective and full right cyclic, which was ineffective. They then experienced a dynamic rollover situation.
