On the 5th of March, 2021, a Robinson R44 helicopter crashed in the outskirts of Xumabee near Sojwe in Botswana. There were two people onboard the R44: The pilot, Leonard Matenje, director for Air Technology Services, treasurer of Professional Hunters Association and the Botswana Wildlife Producers Association, who survived, and Sasa Klaas, a Motswana musician, who died at the scene.^[1][2]

Aircraft

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 August 1, 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]

Investigation

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 into the accident.^{[citation needed]}

According to the final report released on December 6, 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 helicopter was flying at a low altitude approximately at tree-top level with limited visibility due to the lack the of natural lighting (i.e. approximately 1 hour after sunset). The pilot had probably experienced spatial disorientation with the possibility of being under the influence.

• The pilot had arrived late to the ranch, compounded by his habit of flying at night with another during training at Hover Dynamics whereas he was also aided by street lighting and other sources of light.

• The fact that the pilot had departed late in the afternoon from the airstrip contributed to his inexperience in flying solo at night with limited visual references.^[6][7]
