Approximately 156 swashplate support assemblies, P/N 204-011-404-125, were incorrectly machined by a vendor with oversize holes in the two outboard lugs. The vendor attempted to repair the mistake by using oversize bushings in the hole. Bell has rejected the repair scheme and declared the supports unfit for use.
