Preventative Maintenance Techniques
Preventative maintenance is concerned with the early detection of defects (using whatever inspection techniques are specified by the aircraft or component manufacturers) and the repair or modification of the defective parts. The inspection techniques may call for the disassembly of components (before or after cleaning), so that more detailed inspections can be done.
Assessment of the defect effect on the continued integrity of the part will also be required and, following the repair, modification or rejection of the part, reassembly techniques will be used to restore the aircraft to the appropriate level of serviceability.
Troubleshooting techniques are used in the process of identifying the cause of a fault, eliminating the fault and returning the aircraft to service.
