A QantasLink plane has made an emergency landing at Perth Airport after experiencing hydraulic problems.

Qantas said the plane, flight QF1623 from Newman to Perth, landed at 11.36am.

The carrier said no emergency landing was requested by the pilots, but emergency services were in attendance as a normal precaution.

Qantas said all 102 people on board the Fokker 100 aircraft, including 97 passengers and five crew, were accounted for, although two people were transferred to Royal Perth Hospital under non-priority conditions.

Passengers 'could smell kerosene'

Passenger Ross Jenkins told 720 ABC Perth the landing was quite normal.

"What sparked a little bit of interest, we taxied too far down the runway which was unusual," he said.

"We didn't head towards the terminal, and then I looked out the window and there was trailing ambulances and fire engines and other emergency crews.

"I commend the crew and everybody, there was no panic. I could smell kerosene, that could be because I was towards the tail of the aircraft and close to the engines.

"The captain said 'crew to your positions', and then about 30 seconds later 'evacuate, evacuate, evacuate' … the windows came out, and that's probably where the kerosene would have got stronger for some people … and [then we] slid down the wings and out we went."

"There was a bit of anxiety from a few people, there were a few young people on board.

"I'm sure they would have been pretty scared by the whole ordeal but generally speaking everybody was pretty calm because there was no smoke, there wasn't fire so it wasn't a life threatening situation that we were facing."

In a statement the airline said the lead flight attendant alerted the pilots to fumes inside the cabin as the aircraft was taxiing towards the terminal.

"The captain then made the order to evacuate the aircraft," it said.

Qantas said it would be assisting the Australian Transport Safety Bureau with its investigation.

It also thanked the crew for its professionalism and the passengers for their cooperation and understanding.
