FAN BLADE INSPECTION
Maintenance Practices (4.E.d)
Scheduled inspectionPerform a visual inspection on the 24 fan blades andplatforms for a scheduled inspection using the AMM.Check the condition of the fan blades and the bladeplatforms, record damage if found on the fan bladerecording map.
Index the N1 system for the CFM56-7B engine and mapthe:
- fan blade position which has the defect- defect type on the fan blade- size of the defect- evaluate the defect limits using the AMM- is the defect condition under a cycle limitation or not- is the engine with the defects airworthy- do the same for the platforms.
Note: If defects were found on the fan blades, or if theengine experienced an abnormal operating problem, thenan unscheduled inspection is necessary.
