Incident Overview
At approximately 0151 on 12 August 2024, a Robinson R44 helicopter registered VH-ERH collided with the top of a seven-storey hotel building in Cairns, Queensland. The helicopter had been flying for several minutes at altitudes below 500 feet around the city prior to the impact. The pilot sustained fatal injuries, the helicopter was destroyed, and the building was damaged. No occupants of the hotel were injured. A post-impact fire developed on the hotel roof but was contained and subsequently extinguished.
Investigation Findings
The Australian Transport Safety Bureau (ATSB) conducted an investigation into the accident. The ATSB found no airworthiness factors with the helicopter that likely contributed to the accident. The flight was not authorised, and the pilot was not approved to fly the operator's helicopters. The pilot had access to the operator's premises at the airport as they were employed as a ground crew member.
The pilot was affected by a significant amount of alcohol before and during the flight. The pilot further increased risk by conducting the unauthorised flight well below the 1,000-foot minimum altitude allowed for flight over a built-up area. The ATSB concluded that, for reasons unknown, pilot actions resulted in a collision with a building while conducting an unauthorised and unnecessary flight, while affected by alcohol, late at night, at low heights over a built-up area, and without night flying endorsements.
The pilot held a helicopter commercial pilot licence and had experience flying the Robinson R44, but was not approved to fly the operator's helicopters at any time and did not hold the appropriate rating to fly helicopters at night. The pilot had never flown a Robinson R44 at night. The strobe lights were turned off, indicating an attempt to conceal the departure from air traffic control and airport staff.
Additional Context
Aviation transport security regulations are designed to keep unauthorised persons out of airports. However, the pilot, as a ground crew member of the operator, was authorised to have access to the helicopter at Cairns Airport and took advantage of that access. The Civil Aviation Safety Authority has regulations in place to ensure flight safety, but in this case, those regulations were circumvented.
