While flying a shallow approach using NVIS a HEMS helicopter entered low-lying fog. After being startled and blinded by the NVGs, the pilot initiated a go-around but the helicopter briefly contacted the ground.
An AD overrun, an omission of a pre-flight free play check for 18 years and a lack of autorotation practice all feature in this accident.
A 1.1 t load was moved to pylon 151, just the wrong pylon 151. A gust caught the helicopter at the worst moment, just as the longline became taut.
