My elevator hinges were showing signs of wear and the pitch stability was sloppy.Checked the hinges for security.They were fine except they had too much wear between the bolt and hinge.The hinges are plans built with aluminum channel and dash 3 bolts.Decided that the Dean hinges would not work on my elevator because of the amount of rework involved in the retrofit so I did the only thing I could.I installed new dash 3 bolts and left the holes as is.Suprisingly the slack is gone and the pitch stab is much inproved.The hinges have been used for 800+ hours and 20 years service.Tommy W.
