Description of Driving Event:
While demating the ET from the SRB's during OMI S0033, TPS foam damage occurred on the +Y forward crossover area. Scraping noises were heard and interference was observed. The operation was stopped while a deviation to the OMI was written to allow north movement of the crane in an attempt to relieve the interference. The operation proceeded but foam damage was unavoidable due to insufficient clearance. This insufficient clearance was due to incorrect installation of support brackets caused by inaccurate OMI procedures.
