Summary

At about 1125 Western Standard Time on 13 October 2004, a Cessna Aircraft Company 182R (C182), registered VH-WPF, was inbound to Jandakot at 1,500 ft. It was approximately 1 NM south of the aerodrome approach point 'Shipyard' when it conflicted with an aircraft travelling in the opposite direction. The pilot reported sighting the aircraft at close range and initiated a steep right turn to avoid a possible collision. The aircraft were outside controlled airspace and operating under the Visual Flight Rules (VFR). The Australian Transport Safety Bureau classified the occurrence as both an Airprox1 and a serious incident2. Recorded radar data and a subsequent radio transmission, positively identified the other aircraft as a Piper Aircraft Corporation PA28-151 (Warrior), registered VH-PMW.


  1. An occurrence in which two or more aircraft come into such close proximity that a threat to the safety of the aircraft exists or may exist, in airspace where the aircraft are not subject to an air traffic separation standard or where separation is a pilot responsibility.
  2. Annex 13 to the Convention on International Civil Aviation defines a serious incident as:
    An incident involving circumstances indicating that an accident nearly occurred.
    Note 1.- The difference between an accident and a serious incident lies only in the result.
    Note 2.- Examples of serious incidents can be found in Attachment C of Annex 13 and in the International Civil Aviation Organization's Accident/Incident Reporting Manual (Doc 9156).
