## Discrepancy

THIS AIRCRAFT HAS A TURBO NORMALIZING SYS INSTALLED UNDER STCS SA10588SC & SE10589SC.  THE FAILURE OCCURRED IN ONE OF THE COMPONENTS INSTALLED WITH THE STC.  DURING A 500 HR IN SERVICE INSPECTION IAW SI11-01, IT WAS DISCOVERED THAT THE LT EXHAUST MANIFOLD WAS CRACKED.  THE CRACK WAS LOCATED ON 2 SIDES OF THE RECTANGLE SHAPED TUBE WHERE THE TURBO MOUNTING FLANGE IS ATTACHED.  THIS MANIFOLD IS OF AN OLDER BUT STILL COMMON DESIGN.
