1. Disconnect Ground Power: Ensure the aircraft is not receiving any external electrical power. Disconnect all ground power sources before commencing the propeller removal.
2. Secure the Aircraft: Place chocks or blocks behind the wheels to prevent accidental movement. Verify that the aircraft is securely parked and not in the way of any other equipment or personnel.
3. Access the Propeller: Move the engine cowling or propeller hub cover to gain access to the propeller blades.
4. Remove the Propeller Bolts/Nuts: Depending on the propeller design, there may be bolts, nuts, or quick-release mechanisms securing the propeller to the engine shaft or propeller hub. Use the appropriate tools to loosen and remove these fasteners carefully.
5. Support the Propeller: As the final bolt/nut is loosened, support the propeller blade to prevent it from falling and causing injury or damage. Use a wooden block or proper lifting equipment to hold the propeller in place.
6. Unscrew the Propeller: Continue turning the propeller until it completely disengages from the engine shaft or hub. Be cautious not to drop or damage the blades during the removal process.
7. Remove the Propeller Blades: Depending on the propeller type, there may be multiple propeller blades attached to a central hub or directly connected to the engine shaft. Remove all the blades following the same procedure, remembering to support each blade before complete detachment.
8. Inspect and Clean: Inspect the propeller, hub, and engine shaft for any damage, debris, or corrosion. Clean the area where the propeller was mounted.
9. Store the Propeller: Place the removed propeller and blades in a secure, safe location to prevent damage and contamination.
Remember, propeller removal is a critical task that requires proper knowledge, training, and safety precautions. If you're not a qualified mechanic or authorized personnel, it's recommended to have a licensed aircraft maintenance technician perform this task.
