Part: NOZZLE — MISSING (PISTON) · airframe 13,379 hrs
DURING CRUISE FLIGHT, A LOUD NOISE WAS HEARD COMING FROM THE ENGINE COMPARTMENT. FOLLOWED BY AN AIRFRAME VIBRATION, WHICH WAS FOLLOWED BY AN ENGINE SHUT DOWN. AFTER LANDING A LARGE HOLE WAS FOUND IN THE ENGINE CRANKCASE ABOVE THE NR 5 CYLINDER. DURING THE TEARDOWN INSPECTION, IT WAS NOTED THAT THE PISTON COOLING NOZZLE ASSEMBLIES HAD NOT BEEN INSTALLED. IT APPEARS THAT SOMETIME DURING THE ASSY OF THE ENGINE, A STD-1339, PLUG WAS INSTALLED INSTEAD OF A COOLING NOZZLE. THE PLUG EFFECTIVELY BLOCKS OFF THE FLOW OF OIL TO THE BASE OF THE CYLINDERS PREVENTING THEM FROM GETTING ANY ADDITIONAL COOLING AND LUBRICATION.
Part: LOOP — LOOSE (UPPER SILL)
THE LOOP ASSEMBLY IN THE UPPER SILL PLATE OF THE FUSELAGE AFT CABIN DOOR BECAME LOOSE, ALLOWING THE UPPER LATCH AT THE TIP OF THE DOOR TO RELEASE DURING CRUISE FLIGHT. THE TOP PORTION OF THE DOOR INCLUDING THE WINDOW, SUBSEQUENTLY BROKE OFF, DENTING THE LT INBD LEADING EDGE STABILATOR SKIN BETWEEN THE 2 MOST INBD RIBS. NO FURTHER DAMAGE WAS NOTED, AND FLIGHT CHARACTERISTICS REMAINED UNAFFECTED. PRIOR TO FLIGHT THE DOOR APPEARED TO BE SECURELY LATCHED.
