Air Accidents Investigation Branch
Summary:
Whilst taxing for takeoff the wingtip of a Boeing 777-300 collided with the rudder of a Boeing757 which was not fully parked on its stand. The commander of the B757 turned onto the stand centreline without stand guidance and did not inform the ATC ground controller that they were not fully parked, contrary to Heathrow Aeronautical Information Publication (AIP) instructions. The commander of the B777 taxied past the protruding B757 believing it to be fully parked and that the ATC clearance and green taxiway lights implied the route was clear. Previous similar incidents have occurred at Heathrow.
