1500 piston hours- no failures, just left the application of carb heat a bit late a couple of times which resulted in some coughing and spluttering and also some coughing and spluttering from water going through the engine when in the tropics.
4000 PT6 hours- no failures, just one low oil pressure indication that reulted in operating at low power until home.
2000 CFM56 hours- no failures. no non-normals.
