Police have charged a truck driver after a jet engine for an A330 passenger aircraft slid off the back of his heavy vehicle near Sydney Airport.

The 7-tonne engine suffered moderate damage in the incident on Forest Road in Arncliffe about 9.30am on Tuesday, and police were forced to close one side of the road.

The American manufacturer's aviation subsidiary is one of the world's largest makers of jet engines.
