Removing an aircraft’s engine can be one of the most difficult and complicated procedures in aircraft maintenance. Given the enormous variety in aircraft and engine designs, there is no single list of instructions that can be provided as a guideline, as every airframe and every engine layout will inevitably have a different checklist that must be followed. There are, however, universal requirements that every engine will have that must be fulfilled, such as disconnecting and reconnecting the electrical, hydraulic, and fuel supply lines, the intake and exhaust path components, the engine controls, and the engine mounting connections to the airframe. One should always refer to the engine manufacturer’s instructions when performing any type of engine removal or installation.
