Which sequence describes the basic steps for removing a typical propeller?

• A. Remove the spinner and remove safety wire from the mounting bolts; Support the propeller with a sling and mark the alignment between the propeller hub and the engine flange with a felt-tipped pen; Unscrew the mounting nuts and protect the threads of the mounting studs or bolts as the propeller is removed; Place the propeller on a cart for transport.
• B. Remove the spinner and safety wire only; Mark alignment with a felt-tipped pen; Place the propeller on a cart for transport; Unscrew the mounting nuts and protect the threads of the mounting studs or bolts as the propeller is removed.
• C. Mark alignment with a felt-tipped pen; Remove the spinner; Place the propeller on a cart for transport; Unscrew the mounting nuts and protect the threads of the mounting studs or bolts as the propeller is removed.
• D. Protect the threads of the mounting studs or bolts; Remove the spinner and safety wire; Support the propeller with a sling; Mark the alignment between the propeller hub and the engine flange.

Answer: (A)

The sequence emphasizes safe control and precise reinstallation when removing a propeller. Start by removing the spinner and any safety wire from the mounting bolts so you can access the hub and prevent the prop from being held in place unexpectedly. Then support the propeller with a sling and mark the alignment between the propeller hub and the engine flange. Supporting the weight prevents the prop from dropping, and the alignment mark gives a clear reference for reinstalling the prop in its exact orientation, which is important for balance and proper thrust alignment. Next, with the prop secured, unscrew the mounting nuts and protect the threads of the mounting studs or bolts as the propeller is removed to avoid thread damage and ease reassembly. Finally, place the propeller on a cart for transport to keep it safe and out of the work area. Skipping the sling or alignment step can lead to injury or misalignment on reinstall, and failing to protect the threads can cause damage when reassembling.
