Object falling from aircraft involving a Robinson R44 II, 20 km north-east of Sydney Airport, New South Wales, on 2 May 2026

What happened

On the afternoon of 2 May 2026, a Robinson R44 Raven II helicopter was being prepared for a 30 minute ‘doors‑off’ sightseeing flight experience in Sydney, New South Wales, with 2 passengers in the rear seats. The flight was to be operated with the left and right rear doors removed from the helicopter, allowing passengers a wider view and an open-air experience. Both left and right front doors remained on the helicopter and the front left seat was vacant.

After receiving a video-based safety briefing, a ground crewmember boarded the passengers, tethered the passengers’ phones and provided a specific door-off briefing, which included use of the communication headsets and the need for keeping all parts of the body inside the cabin during the flight.

The pilot reported that the departure from Sydney Airport was normal and the helicopter climbed to cruising height and tracked north to the city before following the harbour to North Head. After rounding the head and turning north, the pilot pointed out for interest another aircraft that was tracking parallel to the helicopter. At that moment, the rear right passenger placed their head through the open doorway for a better view. As the helicopter was travelling at around 80 kt indicated airspeed at that time, the slipstream immediately caught and pulled the passenger’s headset rearward, away from their head and leaving it hanging outside the helicopter cabin – retained by the connecting cable. The passenger was able to retrieve the headset using the cable, however the right ear cup cushion detached from the unit and was lost from the helicopter.

After the passenger re-donned the headset, the remainder of the flight was uneventful, and the helicopter sustained only minor scuffs and scratches from the headset contact.

Related occurrences

The US National Transportation Safety Board has undertaken several investigations into accidents and serious incidents resulting from loose objects striking a helicopter’s tail rotor.

• WPR13CA071 – Headset lost from doors-off flight, striking tail rotor
• WPR14CA363 – Jacket lost through open window, striking tail rotor
• LAX03TA150 – Jacket lost through opened door, striking tail rotor
• FTW86LA047 – Life vest lost through opened door, striking tail rotor

Advisory

The helicopter manufacturer published Safety Notice SN-30 in 1994 (revised in 2009) warning of the danger that loose objects present to the safety of flight – particularly with doors-off operations.

Safety message

While many helicopters (including the R44) can be approved for operation with one or more doors removed, doing so eliminates a key defence against objects and items being lost from the helicopter interior. As any item lost has the potential to strike and damage the tail and/or main rotors, doors-off flight inherently increases the operating risk environment, such that countering precautions must be taken.

While the operator’s existing operational procedures provided several sound physical and instructional defences against inadvertent passenger-related loss of items from the helicopter, this occurrence illustrates that it is indeed possible (and human) to ‘get caught up in the moment’ and briefly forget instructions given in briefings and during boarding. In this context, all helicopter operators providing doors-off flight experiences should consider whether further precautions may be applicable and desirable for their own operations. 

About this report

Decisions regarding whether to conduct an investigation, and the scope of an investigation, are based on many factors, including the level of safety benefit likely to be obtained from an investigation. For this occurrence, no investigation has been conducted and the ATSB did not verify the accuracy of the information. A brief description has been written using information supplied in the notification and any follow-up information in order to produce a short summary report, and allow for greater industry awareness of potential safety issues and possible safety actions.
