Police and emergency services are responding to a light plane crash south of Brisbane on Monday.

Initial police investigations indicate the Beechcraft Bonanza light aircraft crashed onto a property on Musch Road at Chambers Flat about 11.10am.

Fire trucks were sent to the scene to contain a grassfire that was sparked by the crash.

The flight left Archerfield Airport 11km south of Brisbane’s CBD at 10.58am, according to flight tracking data.

Police said it is not yet known how many people were on board the aircraft.

A spokesperson from the Australian Transport Safety Bureau (ATSB) said a safety investigation into the incident had commenced on Monday morning. 

“The ATSB has deployed a team of three transport safety investigators from its Brisbane offices, specialising in aircraft operations, maintenance and engineering, to the accident site,” the spokesperson said. 

“They will commence evidence-gathering activities including site and wreckage examination, and the recovery of any aircraft components of interest for further examination at the ATSB’s technical facilities in Canberra.”

Investigators are also set to interview witnesses and collect relevant recorded information from the aircraft’s flight data including the pilot and maintenance records, and weather information. 

The bureau said a preliminary report, detailing information about the circumstances of the accident, will be published in about eight weeks.

Emergency crews remain at the scene.

This is a developing story. More to come.
