What happened
On 22 August 2018, at 1235 Eastern Standard Time, a Bombardier DHC-8 departed Cairns, Queensland (Qld) for a regular public transport flight to Moranbah, Qld.
During initial climb between 600 ft and 1,000 ft, the crew detected severe engine surging. The crew identified the no. 2 engine as the affected engine and shut it down. The crew completed the relevant checklists, declared a PAN PAN[1] and continued climb to 7,000 ft. The crew then returned the aircraft for landing on runway 33 at Cairns.
Engineers replaced the propeller control unit and the over speed governor and returned the aircraft to service.
