The Beech A200 operated on behalf of the United Nations Organization Stabilization Mission in the Democratic Republic of the Congo (MONUSCO). Flight UNO 840 from Bunia was about 5 nm on final for runway 36 at Goma Airport when the flight crew selected the undercarriage down. The gear extension lights were indicating red instead of green to confirm the actual extension. The pilot then executed a go-around and climbed to FL100, then FL 120 to enter a holding circuit.
Attempts were made to deploy the undercarriage by following the emergency checklist procedure, but these attempts failed.
The pilot decided to divert to Kavumu airport in Bukavu in order to carry out a belly landing on the east clearance strip of grassy runway 17. The crew and passengers evacuated the aircraft through the rear door.

Probable Cause:

The probable causes of this accident are a combination of two essential factors:
1. Hardware factor: the refusal to extend the landing gears in electric mode following the malfunction of the fuse that prevented current from being conducted to the gear controls ;
2. Human factor: the lack of familiarity of the crew with the emergency described in the operator's and manufacturer's manual, lack of emergency simulation exercises for the proficiency check in accordance with the regulations in force RACD 08 paragraph (point a)
