The UEX plane was one of ours ( ACA
). They were holding position, and the MHT
tower cleard the NW319 around the CRJ. NW
proceeded to remove a 12"x12" piece of the CRJ's rudder. The 319 was basically un-scathed, but required inspections were obviously due. Our RJ
required a new rudder, which by this time should be installed and the jet should be flying. The FAA is looking into the incident, primarily the towers decision to allow the 319 to move around the RJ
, and the NW
crews decision to do so.
