In-flight break-up involving Robinson R22 Beta, VH-ESG, 42 km south-east of Jericho, Queensland, on 20 April 2026

The occurrence

On the morning of 20 April 2026 at about 0643 local time, the pilot and sole occupant of a Robinson Helicopter Company R22 Beta, registered VH‑ESG, took off from the operator’s helipad near Tambo, Queensland. The pilot’s destination was a property near Jericho (about 150 km from Tambo) to carry out mustering operations. The pilot reportedly intended to land at the property to plan the day’s work. After take-off the pilot flew north and generally maintained a height of about 2,400 ft above mean sea level (AMSL) during the flight which was between 900 ft and 1,400 ft above ground level (AGL) over undulating terrain.

Tracking data (see Recorded data) shows that the helicopter continued north and at 0729 was about 45 km from the destination when it entered a steep descent from about 1,339 ft AGL (Figure 1).

About 10 minutes later, one of the operator’s staff became concerned that there was no further tracking data for VH‑ESG and contacted another of the operator’s pilots, who was mustering by helicopter on a different property, to advise them. The second pilot immediately ceased mustering operations, landed to refuel, then flew to the last known location of VH-ESG. Arriving at the location at about 0942, the second pilot commenced a search and after a short time located the wreckage of VH‑ESG. The second pilot landed. The pilot of VH-ESG had been fatally injured and the helicopter destroyed.

Context

Pilot information

The pilot held a Civil Aviation Safety Regulations 1998 Part 61 Commercial Pilot Licence (Helicopter), first issued in August 2016. The pilot was issued with a class 1 and 2 aviation medical certificate in January 2026, and at this time reported they had accrued about 5,600 flying hours.

Helicopter information

VH-ESG was a Robinson R22 Beta powered by a 4-cylinder, horizontally opposed, Lycoming O‑360‑J2A engine, which was fan cooled. The helicopter was manufactured in 2007 and first registered in Australia on 19 May 2015. The helicopter had been registered to the operator since 20 January 2017.

The last periodic inspection was carried out in February 2026 and at that time the helicopter had accumulated 5,000.2 hours total time in service.

Meteorological information

There were no official weather observations available near the accident location. The nearest official weather observations were obtained from Blackall Airport located 108 km to the south-west, with forecasts obtained for Emerald Airport, 193 km east-north-east, and Longreach Airport, 216 km west‑north‑west.

The aerodrome forecast (TAF)¹ for Emerald Airport issued at 0327 local included a TEMPO² for broken cloud at 1,300 ft above the airport (elevation 624 ft) between 0400 and 0800 local time with a south‑east (120°) wind around 5 kt. The TAF issued at 0513 local for Longreach Airport indicated conditions were CAVOK³ with a south‑east (140°) wind around 9 kt.

The graphical area forecast (GAF)⁴ issued at 0216 local for southern Queensland, and valid at the time of departure around 0643, indicated isolated fog until 0800 and areas of low cloud. The GAF also showed that conditions to the west of the helicopter’s track were forecast to be clear. This was consistent with satellite imagery⁵ which, according to Bureau of Meteorology analysis, showed the development of low‑level cloud and fog signatures in the vicinity of the accident from approximately 0500.

On the morning of the accident, other pilots flying from the operator’s base in Tambo reported a distinct inversion layer⁶ at about 400 ft AGL. They reported the outside air temperature being cold below the inversion layer and warm and humid above it. There was no visible moisture. A further 100 ft above that, there was reportedly another distinct inversion layer where bushfire smoke could be smelt.

A person on the ground about 7 km from the accident site on a ridge line reported there were patchy clouds in the area and there was no rain or fog.

Site and wreckage information

The accident site was located in flat, open farmland. Topographical data showed the accident site elevation was about 424 m above sea level (1,391 ft AMSL). The main wreckage included the cabin, engine, mast, and main rotor assembly (Figure 2).

Both fuel tanks had ruptured due to impact forces. However, there was no fire. 

Damage to the main rotor blades, tail boom, and other components indicated that the main rotor had impacted the tail boom in flight (Figure 3).

Fragments of the tail boom were spread throughout a debris field that extended up to 400 m south of the main wreckage. The tail rotor and gearbox assembly was located about 250 m away from the main wreckage and sections of the tail rotor drive shaft were located throughout the debris field. This spread of debris, along with evidence of the main rotor striking the tail boom in flight, indicates that there was an in‑flight break‑up. 

The impact damage limited the extent to which any pre-impact defects could be identified, however from the evidence available, no engine, flight control or structural issues were identified.

Recorded data

The helicopter was fitted with a TracPlus unit that transmitted the helicopter’s location, altitude, and groundspeed via satellite or a mobile phone network every 15 seconds. This information was monitored by the operator for search and rescue purposes.

The helicopter was also fitted with a Garmin Aero 660 GPS which was retained for further examination.

Further investigation

To date, the ATSB has examined the accident site and wreckage, interviewed witnesses, collected meteorological data, aircraft maintenance and pilot records, and obtained flight tracking data. 

The investigation is continuing and will include further review of: 

• pilot records and medical information 
• aircraft maintenance and flight records 
• recovered components 
• witness information 
• meteorological data 
• recorded aircraft tracking data.

Should a critical safety issue be identified during the course of the investigation, the ATSB will immediately notify relevant parties so appropriate and timely safety action can be taken. A final report will be released at the conclusion of the investigation.

Purpose of safety investigations The objective of a safety investigation is to enhance transport safety. This is done through:  identifying safety issues and facilitating safety action to address those issues providing information about occurrences and their associated safety factors to facilitate learning within the transport industry. It is not a function of the ATSB to apportion blame or provide a means for determining liability. At the same time, an investigation report must include factual material of sufficient weight to support the analysis and findings. At all times the ATSB endeavours to balance the use of material that could imply adverse comment with the need to properly explain what happened, and why, in a fair and unbiased manner. The ATSB does not investigate for the purpose of taking administrative, regulatory or criminal action. About ATSB reports ATSB investigation reports are organised with regard to international standards or instruments, as applicable, and with ATSB procedures and guidelines. Reports must include factual material of sufficient weight to support the analysis and findings. At all times the ATSB endeavours to balance the use of material that could imply adverse comment with the need to properly explain what happened, and why, in a fair and unbiased manner. An explanation of terminology used in ATSB investigation reports is available here. This includes terms such as occurrence, contributing factor, other factor that increased risk, and safety issue.

6. ^    An inversion layer is where the temperature increases with height, rather than decreasing as is normal. A low-level or surface inversion occurs when the ground cools overnight by radiating heat, also cooling the layer of air closest to the ground. These low-level inversions form a stable layer of air, typically extending a few hundred feet and prevent the higher altitude wind from mixing with the lower-level winds near the ground.
