Narrative:At 11:22 Eastern Daylight-saving Time on 2 December 2005, a Piper Aircraft Corporation PA-31350 Chieftain aircraft, registered VH-PYN, departed Archerfield, Queensland, on a private flight to Griffith, NSW. On board were the pilot, an observer-pilot, and two passengers. The en-route weather was forecast to include occasional thunderstorms. At 11:27 EST, a SIGMET was issued advising of frequent observed thunderstorms south of Coonamble, NSW. Air traffic services did not pass the SIGMET information to the pilot of the aircraft, nor did their procedures require the information to be passed. There was no request from the pilot for weather information at any stage during the flight.
After the aircraft passed Coonamble, the pilot reported diverting left of track due to weather. The aircraft then came within air traffic control radar coverage, which showed it flying parallel to track at 10,000 feet, at a ground speed of 200 to 220 knots. At 13:50 EST, the aircraft disappeared from radar and no further radio transmission was received from the pilot. At about 14:00 EST, the wreckage of VH-PYN was found approximately 28 km north of Condobolin, NSW.
The wreckage trail extended for more than 4 km. The wings, outboard of the engine nacelles, the right engine, and sections of the empennage, had separated from the aircraft in flight. The remaining structure impacted the ground inverted and was destroyed by a post-impact fire. No evidence was found that aerodynamic flutter, in-flight fire or explosion, or lightning strike damage contributed to the circumstances that led to the break-up. However, the extent and nature of the damage precluded a complete examination of the aircraft and its systems.
There was evidence that immediately before the accident, the aircraft was likely to have been surrounded to the east, west, and south by a large complex of storms. The aircraft was not fitted with weather radar.
