## Discrepancy

ON INSPECTION, NR 4 CYLINDER EXHAUST PIPE FLANGE DISTORTED AT LEFT TRANSITION.  LEFT TURBOCHARGER HAD BECOME LOOSE AT ENGINE, SHIFTING DOWN SLIGHTLY CAUSING MISALIGNMENT WITH NR 4 PIPE.  FORWARD TRANSITION SUPPORT BOLT (PN LW31-1.69) WAS MISSING.  LYCOMING SB 512 PERTAINS TO THIS SUBJECT WHICH HAS RECENTLY BEEN REPLACED WITH SB 521.
