Safety record

Accident & incident history

2000-10-17 Accident · Dellwood, FL Damage: Substantial Minor injury NTSB · MIA01LA007
Reported aircraft: Robinson R-22 Beta — a different aircraft that carried the N621DM registration before this airframe.
Probable cause: the pilot's failure to clear the area, and his attempted takeoff while the helicopter's right skid was entangled with vines, which resulted in inadvertent dynamic rollover and substantial damage to the aircraft.
