What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) EMS helicopter operated by air methods had flown from mercy hospital in Sioux City, Iowa, to pierson, Iowa, with the pilot and two medical attendants to pick up a patient. After arriving in pierson, it was decided that the patient would be transported by ground transportation. The medical crew that had traveled to pierson on the helicopter returned to mercy hospital with the patient in the ground transportation. The pilot then began the flight back to mercy hospital. He was the sole occupant on the aircraft. While in cruise flight, the ceiling began to lower. The pilot flew the aircraft at 600 to 700 feet AGL to remain in VFR conditions. While diverting the helicopter around lowering weather conditions, the pilot inadvertently allowed the aircraft to descend during a turn and struck powerlines. There was damage to the wire strike protection brace, right windshield, radome, and one antenna. The powerline wires were cut and poles damaged. privacy data omitted
