Final Report


On 23 September 2016, a Network Aviation Fokker F28 MK 100 aircraft, registered VH-NHY, departed Newman Airport, Western Australia, on flight 1623 to Perth Airport, WA. On board were two flight crew, three cabin crew and 97 passengers.

About 550 km north of Perth, the flight crew were alerted to a caution for low quantity in hydraulic system 1. The flight crew completed the checklist actions, which included selecting the hydraulic system 1 pumps off. Without hydraulic system 1 there is no nose-wheel steering available to the flight crew. Therefore they arranged for a tug to be available to tow the aircraft from the runway to the gate. Rather than use the engines for electrical power and air-conditioning during the aircraft tow, the captain elected to start the auxiliary power unit during the approach. The APU would then supply air for the air-conditioning system after landing and electrical power after the engines were shut down. The aircraft landed without further incident and rolled through to the end of runway 21.

At the end of runway 21, the flight crew could not see a tug waiting for the aircraft, so they used differential braking to turn the aircraft off the runway and onto the taxiway before stopping. After stopping the aircraft on the taxiway the cabin crew manager reported to the captain that there were fumes present in the cabin. An emergency evacuation was conducted. During the emergency evacuation, three passengers received minor injuries.

This incident highlights the importance of training and procedures, and the need for organisations to educate their workforce about safety incidents. The flight crew on board NHY were confronted with two consecutive emergencies. They responded to each situation in accordance with their training and procedures, which resulted in everyone safely evacuating the aircraft with only minor injuries reported.
