On 11 May 2018, a Bombardier CRJ1000 climbing on departure from Tambolaka and an ATR72-500 descending inbound there lost safe separation when during opposite turns in visual flight in uncontrolled airspace. Prompt response to both coordinated TCAS RAs resolved the conflict. The Investigation found the departing flight Captain mixed up left and right downwind circuit joining by the ATR 72 and that his inexperienced First Officer had not picked this up. It also noted that this Captain may not have been fit for duty and that all parties may have failed to fully recognise the limitations of ANSP ‘information’ service.
