## Discrepancy

DURING PHASE 3 INSPECTION FOUND PROPELLER SPINNER CRACKED AT BLADE CUT OUT ON ONE SIDE.  THE PROBLEM IS REOCCURRING, THIS IS THE 5TH SPINNER REPLACEMENT ON THIS AIRCRAFT IN 1928.0 HOURS AND IS A COMMON PROBLEM ON OTHER C-172S AIRCRAFT.  CESSNA SERVICE BULLETIN SB02-61-01 WAS ACCOMPLISHED 45.6 HOURS AGO WHICH REQUIRED ELONGATING THE MOUNTING SCREW HOLES TO ACHIEVE A GAP OF LESS THAN 0.03 BETWEEN SPINNER AND AFT BULKHEAD.  THE MATERIAL THICKNESS OF THIS P/N SPINNER IS HALF THE THICKNESS OF THE OLDER CESSNA AIRCRAFT SPINNERS AND IS THE REASON FOR THE CRACKING AS IT IS NOT A PROBLEM ON THE OLDER CESSNA AIRCRAFT.
