TROUBLESHOOT THIS SYSTEMDefine the reported symptom, confirm aircraft and configuration applicability, then follow current approved fault-isolation and maintenance data.
Why it exists
Lubricate and cool engine bearings and gears while removing contaminants and providing condition information.
What belongs here
- Oil tank
- Pressure and scavenge pumps
- Filters and bypass indication
- Oil coolers
- Bearing sumps and seals
- Breathers and deaerators
- Quantity, pressure and temperature sensing
- Chip detectors where installed
What users may see
Oil quantity, pressure and temperature, filter bypass, low-pressure warnings and maintenance indications may be shown.
What technicians commonly evaluate
Correct servicing, consumption trends, leaks, filter and chip-debris evaluation, pressure and temperature trends, seal or breather condition and post-maintenance leak checks are common concerns.
