Narrative:
On the morning of 26 December 2022, a Stoddard Hamilton Aircraft Glasair Super II FT, registered N600, was operated on a private flight under the visual flight rules (VFR) from Bankstown, New South Wales (NSW) to Temora, NSW, then Temora to Wedderburn, NSW. The purpose of the flight was to test the aircraft on its first flight in Australia and reposition the aircraft to Wedderburn. The pilot and passenger were both co-owners of the aircraft.

Air traffic control audio recorded the aircraft departing Bankstown Airport at about 1003 local time. Flight tracking data obtained from ADS-B Exchange and FlightRadar24 showed the aircraft being flown to Temora, landing at about 1133 on runway 36. The aircraft was then refuelled, with OzRunways data showing that the aircraft conducted 2 circuits from runway 05 between 1229 and 1246. Flight data also indicated that, about an hour later, at 1323, the aircraft departed Temora via runway 18 for Wedderburn.

On arrival at Wedderburn, N600 was positioned on a wide circuit and landed on runway 17 at Wedderburn at 1452. For unknown reasons, the aircraft then became airborne again. Eyewitnesses and CCTV at Wedderburn observed the aircraft in a shallow, unstable climb, enough to just clear rising terrain and trees at the end of runway 17. After clearing the trees, the aircraft then disappeared from view and about 2 minutes later collided with terrain about 2.7 km from the end of the runway, approximately 150 m from Appin Road. The wreckage was consumed by a post-impact fire that also started a small bush fire. Both occupants sustained fatal injuries.

N600 was a Stoddard Hamilton Aircraft Glasair Super II FT, amateur built aircraft constructed in the United States (US). The aircraft was a conventional two-seat, single-engine, low-wing monoplane with tri-cycle undercarriage, built mostly of fiberglass. The aircraft was fitted with a Subaru EJ-25 automotive engine, modified for aviation use by NSI Propulsion Systems (later Maxwell Propulsion Systems). The first flight was conducted on 4 June 2014 at Chesapeake Regional Airport, US. About 60 hours flight time was accumulated before the aircraft was imported into Australia in 2021.

Prior to leaving the US, the aircraft’s one-piece wing was disassembled to facilitate shipping. Subsequently, upon arrival in Australia, significant work was undertaken to restore the aircraft to an airworthy condition prior to its first flight in Australia on 26 December 2022. The aircraft was not equipped with a flight data recorder or cockpit voice recorder, nor was it required to be.

Campbelltown and Bellambi are the closest aviation weather reporting sites to Wedderburn Airport, with the accident site being roughly half-way between the two. The Bureau of Meteorology’s routine report of the weather conditions at Campbelltown at 1500 (6 minutes after the accident) showed an east-north-eastly wind at 8 knots, gusting to 15 knots, with an air temperature of 33.2°C and a dew point temperature of 8.6°C. It also showed that no rainfall was recorded since 0900 that morning.

The Bellambi Airport weather report at 1500 local time showed a north‑north-easterly wind at 12 knots, gusting to 16 knots, with an air temperature of 23.7°C and a dew point temperature of 20.0°C. It also showed no rainfall recorded since 0900 local time that morning.

CCTV footage from Wedderburn Airport showed clear skies and a crosswind with an easterly quartering tailwind during the landing and subsequent take‑off.

To the extent possible due to the condition of the wreckage, on-site examination of the aircraft’s flight controls and structure did not identify any pre‑existing faults or failures. However, several components were retained by the ATSB for further examination, including the engine, gearbox, propeller, and electronic devices.

As the aircraft was registered with the Federal Aviation Authority (US), it was operating in Australia under a Civil Aviation Safety Authority (CASA) Special Flight Authorisation Instrument. The CASA instrument was valid until 31 October 2024 and stated that the aircraft must not be operated over a populous area.
