CASA spokesman Peter Gibson said the remote-controlled airplane incident, which was documented in a video placed on the Web site YouTube, is being investigated to determine what breaches of safety guidelines may have been broken, The Times of London said Wednesday.
"There are a number of possible breaches," Gibson said of last Friday's incident at Perth airport.
"Obviously we've only got the YouTube video to go on, which may or may not even be real, but we are looking into whether the safety of the plane was breached."
The model airplane reportedly came within 100 feet of a Virgin Blue jet before becoming trapped in the vehicle's jet wash.
The Times said the unidentified operator of the model airplane could potentially face up to two years in prison if convicted of violating CASA guidelines.
