The South East corner of BSC 9 had the HEPI housing installed incorrectly causing the foot to have insufficient clearance around several points. The bolts had been over-torqued and/or the tapped holes had chips and one bolt galled. A sawzall was used to chop through the bolt, and then a drill was used to remove the rest. After retapping the hole ~75% of the threads remained, which should be sufficient for only a 45ft-lb torque. Additional holes had to be drilled and tapped to allow the clamps to be used with the new housing position. The housing was reinstalled and the support tube should be within a couple thousandths of where it was originally sited in.
