Preliminary information suggests problems with the landing gear may have prompted the return.

On Sep 27th 2020 The Aviation Herald received the preliminary report stating that the crew reported they could not retract the landing gear and noticed a hydraulic problem (pressure indication was 10 psi, quantity had dropped to zero, actual hydraulic system pressure reduced to 800 psi which even rendered alternate brakes unserviceable) shortly after departure and requested to return to Mogadishu. The crew was aware they had lost all hydraulic fluid, prepared accordingly by manually extending the landing gear which resulted in three green indications, the crew manually extended the flaps, proceeded to perform the normal landing checklist but knew, they had only one application of brakes left and no steering. The aircraft performed an approach to runway 05, touched down at 104 knots over ground, then the crew lost control and the aircraft veered to the right and collided with the airport perimeter wall. Two crew received serious and two other crew minor injuries.

The captain (42, ATPL) had accumulated 12,000 hours total and 5000 hours on type.

The aircraft, built in 1989, accumulated 37,793 hours total flight hours. The aircraft had been registered in Kenya on Aug 19th 2019. The last certificate of airworthiness had been issued on Sep 11th 2020 and was valid through Sep 10th 2021.
