Analysis

The acft was second in a flt of three spraying forest area with dimilin when it contacted a power line suspended between two hilltops. The prop severed the single strand of cable and shortly after the engine lost power. The plt maneuvered for an emgcy lndg, jettisoned the chemicals, and extended flaps. The acft overshot a clearing and the acft settled into the trees. The plt stated that the accd may have been prevented if better recon had been done prior to the spraying operation.
