Bell 222, Aurora, Ill., Oct. 15, 2008–The crash of the medevac helicopter into a radio tower was caused by the pilot’s failure to maintain clearance from the 734-foot-tall lighted structure due to inadequate preflight planning and a flight route too low to clear the tower, according to the NTSB. The helicopter was destroyed in the collision and ensuing fire, killing the pilot, flight paramedic, flight nurse and infant patient. Air Angels was operating the helicopter as an EMS transport. The accident occurred 10 minutes after takeoff as the flight headed to Children’s Memorial Hospital Heliport in Chicago in night VMC.
The helicopter was equipped with a Garmin GNS 430, which included GPS, navigation and communications radios, and its Jeppesen aviation database had last been updated four months before the accident. The company’s director of flight operations told investigators the unit was the operator’s primary source of navigation information. The unit could display terrain and obstacles, but the software for that capability had never been installed.
