## Discrepancy

HEAD SEPARATED AT DOME.  SEPARATION STARTED AT 4 O'CLOCK POSITION AND 11 O'CLOCK AND PROPAGATED UNTIL TOTAL FAILURE.  EXHAUST AND OIL DRAIN HELD CYLINDER ON ENGINE, 900 SMOH.  SUBMITTER STATED BETTER DYE-PEN INSPECTION AT OVERHAUL WITH PARTICULAR ATTENTION TO EXHAUST PORT.  RETIRE CYLINDER AFTER SECOND RUN.  CYLINDER WAS OVER 20 YEARS OLD.  AGE MAY HAVE BEEN A FACTOR.
