NORTH BEND - An update to a story that KCBY first told you about at Five, as KCBY learns more about the cause of the helicopter maintenance accident that happened Wednesday at the Southwest Oregon Regional Airport.

According to Ed Langerveld, who owns the Ocean Air emergency airlift helicopter, it was a malfunction in the flight control system, that caused the helicopter, which was not in flight, to flip over and topple on its side to the ground.

"When the maintenance personnel went to full power in the helicopter, the blade started to speed up," says Langerveld. "The top portion went out of control and tilted the helicopter and then it flipped over to 90 degrees to the pavement."

The incident happened at 1:33 p.m. when witnesses heard a loud crash and saw the plane's rotor blades shattered and landing gear broken, with debris scattered about 75 feet in all directions.

North Bend Police and Fire responded within a matter of minutes. Assistant Fire Chief Jim Brown says fortunately there no injuries, and all safety precautions were in place at the time.

Langerveld estimates a total loss of $400,000 in damages, but he believes it won't affect their business since they have 15 airplanes and two other helicopters in use.
