ATSB investigates 1979 Beechcraft A36 Bonanza crash near Brisbane that killed Barambah Organics founder and his daughter

A Beechcraft A36 Bonanza built in 1979 crashed into a paddock at Chambers Flat, near Logan south of Brisbane, killing Barambah Organics founder Ian Campbell, 56, and his daughter Hannah, 23. The six-seat aircraft had taken off from Brisbane's Archerfield Airport at 10.57am on Monday, reached 1,000 feet by 11.00am, then entered a five-minute descent before striking the ground and catching fire at 11.05am, roughly eight minutes after departure.

Witnesses reported thick black smoke from the engine shortly after take-off and described the engine as sounding rough or spluttering. Air traffic control struggled to maintain radio contact with the aircraft before the crash, and it is unclear whether any mayday calls were made. Campbell, a pilot of more than 25 years' experience, had rented the aircraft from Queensland-based charter and rental firm Telford Aviation, and public flight records indicated this was its first logged flight since 31 July.

Telford Aviation bought the aircraft in 2022 for $350,000 from a retired airline pilot who had previously flown it extensively around Australia, including over water. A 2022 sales listing described a "no expense spared" renovation carried out by that former owner, who had acquired the plane in 2004, fitted a new engine, and replaced the interior with lounge-style seating and tailored floor coverings. The aircraft was built in the United States in 1979 and delivered to Australia the same year via a transpacific ferry flight.

The ATSB deployed three investigators to the site from Monday afternoon. They examined the wreckage, checked flight control continuity, inspected the engine and propeller, and recovered recording devices including avionics equipment and GPS units for analysis at ATSB facilities in Canberra. Acting Chief Commissioner McNamara said the aircraft and engine would be available for further examination once recovered.

Fatal accidents involving older single-engine piston aircraft typically turn on the same set of questions: engine condition, maintenance continuity, and gaps between flights. A nearly 50-year-old airframe with a documented ownership history, a replaced engine, and a period of inactivity before its final flight gives investigators several threads to reconcile against the reported engine sounds and the short, steep descent.

Charter and rental operators depend on service records and logged flight history to establish that an aircraft is airworthy between uses, particularly after a gap like the one recorded here since 31 July. How thoroughly those records were checked before this flight, and what the engine and propeller inspection shows once the wreckage is fully recovered, will shape whether this is treated as a maintenance, mechanical, or operational question.

The recovered avionics and GPS data, along with the ATSB's examination of flight control continuity, should narrow down the sequence between the reported rough-sounding engine and the loss of radio contact. Acting Chief Commissioner McNamara's confirmation that the aircraft and engine will undergo further examination once recovered marks the next concrete step in establishing what happened during those eight minutes.
