## Discrepancy

SPINNER CONTACTS PROPELLER BLADES AT LEADING EDGE AND TRAILING EDGE OF BLADE CUTOUTS IN THE SPINNER.  A GROOVE HAS BEEN WORN INTO THE PROPELLER BLADES, WITH THE WORST BEING .080 INCH DEEP AND .9 INCH LONG ON THE LEADING EDGE OF ONE BLADE.  SPINNER AND BOTH SPINNER BACKPLATES WERE DESTROYED BY CRACKING CAUSED BY THE LACK OF MATERIAL THAT WAS WORN BY PROPELLER INTERFERENCE.  DAMAGE OCCURRED DUE TO NORMAL OPERATIONS, WITH NO KNOWN STRIKE TO EITHER THE PROPELLER OR SPINNER ASSY.  TO PREVENT RECURRENCE, A SPINNER ASSEMBLY NEEDS TO BE INSTALLED WITH EITHER LARGE ENOUGH BLADE CUTOUTS, OR EXTENDED BACKPLATES TO PREVENT INTERFERENCE WITH THE PROPELLER.  DAMAGE WAS FOUND DURING AN NORMAL INSPECTION.
