- Compliance with all applicable inspection SBs is verified.
- A full hot section inspection is performed. Exposed gas generator surfaces must be corrosion-free and all missing diffusor ducts must be replaced. Turbine blades must show no or minimal sulphidation (stage 1 maximum allowable).
- Ensure compressor is free of corrosion.
- All foreign object damage to compressor must be repaired.
- Inspect the AGB starter generator drive pad splines for wear.
- Ensure all external surfaces meet all corrosion and damage requirements. Repair generator and cast housing surfaces with touch-up paint. Clean and inspect the gas generator drain valves.
- Remove and inspect the external pneumatic hoses and tubes (Px and Py tubes) for cracks or other damage.
- Perform all oil system checks.
- Inspect accessories. Inspect controls, linkages, leads and connectors. Check temperature indicating system including T1 probe trim resistance.
- Check the operation and/or calibration of all engine-related instrumentation.
Option B also includes operation and maintenance requirements that need to be maintained once an engine is registered on the program including engine performance monitoring, compressor washes, fuel nozzle inspections, compressor first-stage inspections, engine control checks and adjustments, propeller balancing, and instrument gauge checks. A yearly report must be supplied to P&WC with a status update relative to these operation and maintenance requirements.
This has been a brief primer on some of the changes in SB 14003 that affect 1900 operators. For more information, contact P&WC or Raytheon Airline Aviation Services.
