At about 17:00 Pacific time, a Bell 206B and Gulfstream G-IV collided in a non-movement area of the San Diego International-Lindbergh Field. The pilot of the helicopter and his three passengers were uninjured and the eight occupants of the Gulfstream were uninjured. The helicopter was on the ground and the Gulfstream was taxiing past it with the assistance of line personnel. As the jet approached the helicopter, a wing walker signaled there was sufficient clearance to pass. But as the jet passed, the helicopter pilot started the engine and the rotor blades struck the jets right winglet. The rotors then struck the helicopters tailboom.
