A COMPLETE AND COMPREHENSIVE
MAINTENANCE METHOD
The MORE STC affords an on condition maintenance concept by increasing the frequency and thoroughness of routine engine inspections. It combines five elements into an integrated, comprehensive and systematic maintenance method.
The main elements of the MORE STC are:
Periodic Engine Performance Monitoring
Periodic Oil and Oil Filter Debris Analysis
Periodic Engine Vibration Analysis
Periodic Borescope or Visual Inspection of the Hot Section
Periodic CT Blade Overhaul Inspection
The following inspections normally prescribed by P&WC are performed at a shorter inspection interval. (e.g. Fuel Nozzles, Bleed Valve(s), Chip Detector, Power Plant Cleaning, Fuel Pump Filters, Compressor Visual Inspection, Power Turbine Visual Inspection, & Propeller Balancing)
The engine is separated into four modules (i.e. Power Section, Compressor, Hot Section and Accessories). This is intended to allow the modules to be repaired separately, if / when appropriate.
