Study Notes
Transfer of Aeronautical Products
- The transfer of aeronautical products between aircraft is not recommended for troubleshooting purposes when a serviceable product is available from the logistics pipeline.
Troubleshooting Charts
- Troubleshooting charts, also known as fault remedy tables, are used in aircraft maintenance manuals to guide maintenance personnel in isolating faults.
- The charts provide common fault symptoms and corresponding corrective actions.
- Example: Hydraulic Brake Troubleshooting Chart, which lists probable causes and corrective actions for various brake-related issues.
Flow Charts
- Flow charts are schematic representations of processes used to guide maintenance personnel through fault finding processes.
- They use boxes to represent steps and arrows to connect them in order.
- The two most common types of boxes in a flow chart are:
- Processing steps (activities) denoted as boxes
- Decisions denoted as diamonds
Troubleshooting Examples
- Example 1: Number 4 engine will not rotate - troubleshoot the problem and suggest a rectification.
- Example 2: Number 4 engine starter motor will not disengage - troubleshoot the problem and suggest a rectification.
- Example 3: Gas Turbine Engine Ignition Systems Troubleshooting - troubleshoot indications using information learned during the Ignition Systems Topic.
- Example 4: Fuel Pump Troubleshooting - troubleshoot indications using information learned during the Fuel Systems Topic.
