## Discrepancy

(GGBR) THE ENGINE SUFFERED CATASTROPHIC FAILURE DUE TO ENGINE OIL STARVATION CAUSED BY THE FAILURE/BREAKAGE OF THE TURBOCHARGER RETURN OIL LINE FITTING AT THE REAR OF THE ENGINE. THE LOSS OF ENGINE OIL ULTIMATELY RESULTED IN THE UNCONTAINED FAILURE OF THE NR 4 CYLINDER CONNECTING ROD THROUGH THE TOP OF THE ENGINE CASE. OUR POLICY HAS BEEN MODIFIED TO INCORPORATE THE REPLACEMENT OF ALL FLUID CARRYING ALUMINUM FITTINGS IN CONJUNCTION WITH ENGINE REPLACEMENT/ O/H.  RECOMMEND THAT THERE BE A LIFE LIMIT ESTABLISHED FOR ACFT ALUMINUM FITTINGS.
