The pilot reported that when on short final for runway 14, a golf ball passed from left to right, in front of, and higher than the nose of the aircraft. SAFETY ACTION The Federal Airports Corporation (FAC) was informed and the Airport General Manager discussed the occurrence with the local Council. A public park located beneath the approach path to runway 14 was frequently used for golf practice. The Council reacted promptly by prohibiting golf practice in the park and signs were placed to warn the public. FAC Duty Safety Officers were requested to increase patrols of the area to warn off anyone seen playing golf in the area. Subsequently, a golf practice area was established in an area nearby which is clear of the approach path to the runway and meets Civil Aviation Safety Authority regulatory requirements.
