What happened

On 11 September 2016, the pilot of a Cessna 172RG, registered VH-MKG (MKG), was observed moving the aircraft out of a hangar at Parafield Airport. The aircraft was positioned on the apron in front of this hangar. The pilot then hand swung the propeller to start the engine, with no one at the aircraft controls. Following the hand start, the uncontrolled aircraft taxied a short distance before colliding with a parked Piper PA-32 Saratoga. Although not struck directly by the propeller, the pilot was fatally injured either by being struck by the aircraft or in the subsequent fall as the aircraft taxied away. The pilot's dog was unsecured in the aircraft.

What the ATSB found

The ATSB found that the battery installed in MKG had insufficient charge to start the engine, and that the pilot started the engine by hand swinging the propeller. The aircraft was not adequately secured during the hand start, resulting in fatal injuries to the pilot and damage to another aircraft when it taxied without pilot control.

Safety message

Hand swinging an aircraft propeller is recognised across the aviation industry as a hazardous procedure. Although hand swinging is permitted under the civil aviation regulations, it should only be undertaken when no other alternatives exist to start the aircraft engine and all necessary precautions have been taken to mitigate the hazards.

Additionally, unrestrained animals in the aircraft cabin have the potential to adversely affect safety during aircraft operations.
