On 5 March 2021, a Robinson R44 helicopter crashed on the outskirts of Xumabee near Sojwe in Botswana.

The helicopter involved in the accident was a Robinson R44 II, with registration ZS-SBM. [3] The helicopter was previously involved in a minor accident on 1 August 2015, that resulted in the left skid collapsing. The cause of that accident was the result of a student performing an autorotation landing with decaying rotor RPM. [4] [5]
The Ministry of Transport and Communications released a statement stating the Directorate of Accident Investigation in the ministry and the Civil Aviation Authority of Botswana (CAAB) had started to investigate the accident.[ citation needed ]
According to the final report released on 6 December 2021, by the Directorate of Accident Investigation in the ministry (DAI), the report stated that:
"The probable cause of this occurrence was the helicopter's tail rotor colliding with terrain and leading to the helicopter's crash."
The DAI also identified the following contributing factors:
The Robinson Helicopter Company, based at Zamperini Field in Torrance, California, is an American helicopter manufacturer. As of 2024, Robinson produces three models: the two-seat R22, the four-seat R44, both of which use Lycoming piston engines, and the five-seat R66, which use Rolls-Royce turbine engines.
The Robinson R22 is a two-seat, two-bladed, single-engined, light utility helicopter manufactured by Robinson Helicopter Company. It was designed in 1973 by Frank D. Robinson, and has been in production since 1979.
The Robinson R44 is a four-seat light helicopter produced by Robinson Helicopter Company since 1992. Derived from the company's two-seat Robinson R22, the R44 features hydraulically assisted flight controls and a larger engine. It was first flown on 31 March 1990 and received FAA certification in December 1992, with the first delivery in February 1993.
The vortex ring state (VRS) is a dangerous aerodynamic condition that may arise in helicopter flight, when a vortex ring system engulfs the rotor, causing severe loss of lift. Often the term settling with power is used as a synonym, e.g., in Australia, the UK, and the US, but not in Canada, which uses the latter term for a different phenomenon.
Bristow Helicopters Flight 56C was a helicopter flight that flew between Aberdeen and the Brae Alpha oil rig in the North Sea.

The flight was carrying 16 oil workers from Aberdeen to an oil platform at the Brae oilfield. All 18 people on board survived.
