Installing Aircraft Parts:

Prior to fit remove the label from the engine and attach it to the paperwork for safekeeping. Check the engine over to ensure it is complete and check the label for any tasks required before fit. Fit any dress items that need to be fitted prior to fit.
Check round the bay to ensure it is clear to fit the engine and remove the jury strut if fitted. Check the lift gear is correctly installed and that it is serviceable.

Position the engine and correctly attach it to the lift gear (double check this).

Lifting the engine in follows the same basic rule as lowering. If using mini hoists there is no need to operate the brake when hoisting as it ratchets. When the engine nears the installed position the person in charge and his assistant will align the mounts and fit the pins or bolts, this is a critical time and may require very small movements on the lifting gear to allow the mounts to be connected. Great care and concentration is required to prevent damage or injury. Do not use your finger to check alignment as a very small movement of the engine could trap or sever it.

Once the mounts are made, and locked the lifting gear can be removed and the engine systems and accessories can be reconnected which is the reverse of the removal. Remember to fit new seals to the components.

After engine fit the electrical systems can be reset. The LP fuel valve opened and the engine fuel system bled to remove any air. The engine oil system is then checked and followed by an engine ground run. During the ground run leak and performance checks are carried out to ensure that the engine is satisfactory. After the run the chip detectors are checked and duplicate inspection is required on the engine controls.
