Gulfstream GIV, Newark, N.J., March 16, 2005–The NTSB blamed the ground collision of a Boeing Business Jet (BBJ) and a Gulfstream GIV on the Boeing flightcrew’s misjudged clearance of the parked Gulfstream during taxiing.
The BBJ 737-72T started taxiing out of the Signature Flight Support ramp area at Newark Liberty International Airport without ground personnel assistance. A ground crewmember was waiting to help the Gulfstream GIV that was parked on the ramp, ready to taxi. He moved into position to help marshall the Boeing and was joined by another ground crewmember who acted as right wingwalker. The marshaller signaled the Boeing to turn right, but the 737 kept moving, so the marshaller signaled him to stop. Its left winglet hit the rudder of the GIV. No one was injured. The 737 winglet had minor damage, while the GIV sustained substantial damage.
