PT6A ENGINE MAINTENANCE Key Maintenance Actions Oil Level Check Oil Filter Inspections Chip Detector Inspection & Airframe Chip Light System (where fitted) Fuel Nozzle Inspections & Functional Testing Borescope Inspections Engine Washing Ground Performance Check P&WC Proprietary Information

84

PT6A ENGINE MAINTENANCE Periodic Inspection Interval Tolerance Ref. Engine Maintenance Manual Chapter 71-00-00, Periodic Inspection Table 10% Tolerance added for periodic inspection task intervals


85

PT6A ENGINE MAINTENANCE Oil Level Check Be Consistent! 15 – 20 min after engine shutdown is recommended If more than 30 min has passed and dipstick or sightglass indicates low, start engine and run at ground idle for 5 minutes, then recheck oil level


86

PT6A ENGINE MAINTENANCE Oil Filter Inspections / Replacement Oil Filter Inspection Inspect initially at 100 hrs with extension to relevant airframe zone inspection based on experience, not to exceed 200 hrs. Oil Filter Replacement To be accomplished every 1000 hrs


87

PT6A ENGINE MAINTENANCE Chip Detector Inspection Check for magnetic debris and perform continuity check every 100 hrs with extension to relevant airframe zone inspection based on experience, not to exceed 200 hrs. For airframe indication systems, the circuitry must be checked every 100 hrs with extension to 400 hrs maximum based on inspection results


88

PT6A ENGINE MAINTENANCE Fuel Nozzle Maintenance Why perform fuel nozzle maintenance? Ensure proper spray pattern Prevent drooling, spitting and streaking


89

PT6A ENGINE MAINTENANCE Fuel Nozzle Maintenance Consequences of poor fuel nozzle maintenance: Cost You Money Local overheating/burning Improper flame propagation Combustion liner distress Small exit duct burning CT Vane burning CT Blade breakage Compressor Turbine Vane Airfoil damage

Can also affect your warranty claims P&WC Proprietary Information

90

PT6A ENGINE MAINTENANCE Fuel Nozzle Maintenance Maintenance Manual Recommendation 200 hours for new operators and can be escalated to 400 hrs based on operators experience Note: Do not double the interval, increase in steps based on experience


91

PT6A ENGINE MAINTENANCE Borescope Inspection Purpose Allow for inspection of critical hot section components such as the CT vane, CT blades and combustion chamber. Also useful for inspections of the 1st stage compressor rotor and 2nd stage power turbine blades.

Interval To be accomplished in conjunction with the scheduled fuel nozzle cleaning / testing.

PT6A ENGINE MAINTENANCE Engine Washing 3 Types of Engine Washing Compressor Desalination Wash Turbine Desalination Wash Performance Recovery Wash


94

PT6A ENGINE MAINTENANCE Engine Washing Maintenance Manual recommendations Compressor and CT desalination wash schedule is based on environment and experience Operators flying in salt laden/polluted environment should perform daily wash After last flight of the day Minimum water quality: drinkable water Engine preservation also to be adapted to environment When engine is exposed to severe environment, more stringent preservation schedule is to be followed as defined in EMM


95

PT6A ENGINE MAINTENANCE Engine Washing Best Results are obtained when: Compressor wash is performed after last flight of day to prevent salt deposits from doing damage overnight Compressor Turbine wash is performed following the Compressor wash since salt and other contaminants are washed from compressor into the hot section
