Three people were killed when a medical helicopter crashed in wooded, rough terrain in northern Wisconsin. The pilot and two medical crew members were returning from delivering a patient to a Madison hospital at the time of the crash.
Authorities said that the Eurocopter AS350 helicopter’s GPS signal vanished shortly before 11 p.m. Approximately 25 minutes, dispatchers received a call that the chopper was missing. The wreckage was found 12 miles south of their destination. The cabin was crushed, and its rotors appeared to have been sheared off. Debris could be seen 100 yards away.
The cause of the crash is being investigated by the National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA). Although a preliminary report is expected within the next two weeks, a full report could take at least a year. Investigators will be focusing on the weather at the time of the crash, the pilot’s background and training, and the chopper’s maintenance logs.
