A Dassault Falcon 10 corporate jet, F-GJMA, landed at Madrid, runway 33, at 19:42. The next aircraft landing on runway 33 was a Hunting Boeing 727-223 (EI-HCD) cargo plane. Both aircraft vacated the runway at taxiway K-1, but the Falcon 10 used a taxiway parallel to the one which EI-HCD was using while heading for the apron. At the intersection of taxiways A-8 and M-8 both aircraft collided. The Falcon 10 was damaged beyond repair. CAUSES (translated from Spanish report): “As a result of the aircraft F-GJMA rolling onto the outer taxiway and lost separation with EI-HCD for not having followed the initial instructions from the control tower, and that the latter was moving too fast on Taxiway A, from a certain point the two aircraft started rolling almost in parallel. When the ground controller realized the situation it was too late to avoid the collision between the two aircraft in the incorporation of the outer taxiway and Taxiway A.”
