On April 2, 2003, at approximately 1620 mountain standard time, a Hughes 369D helicopter, N56SM, was substantially damaged when it impacted terrain during a reversal maneuver near Estes Park, Colorado. The commercial pilot and his private pilot crewmember were not injured. Aris Helicopters of San Jose, California, was operating the flight under Title 14 CFR Part 91.

He tried to turn the helicopter around, but hit the ground, breaking the helicopter's right skid. The aircraft rolled over onto its right side, and its main rotor blades separated from the helicopter. The density altitude at the time of the accident was calculated to be 13,068 feet.
