The pilot was engaged in spraying a wheat crop. Two large trees, 18 metres apart, were situated in the centre of the paddock and the pilot intended to fly between the trees during one of the spray runs. He positioned the aircraft to fly under overhanging foliage and as close as possible to the tree on his right. As the aircraft passed the tree the right wing struck a dead branch. The pilot was able to maintain control of the aircraft and subsequently landed at the DEPARTURE strip. The pilot had failed to notice the dead branch protruding beneath the foliage of the tree.
