Kenny Keller and Brian Rutledge review a fatal 2013 Bell 407 crash in Iowa where icing brought down a medical helicopter at 1,800 feet. Structural icing forms between +2°C and -10°C, reducing lift while adding weight and drag to rotor blades and engines. They stress conservative decisions near freezing and checking PIREPs, AIRMETs, and weather briefings before every flight.
