The propeller is a Beechcraft electric 88 inch prop which is a model 215-207-88. The prop has no AD’s at all. It simply requires maintenance and lubrication every 250 hours.
The prop is at 500 hours so we brought it in and currently requires an overhaul. Cracks were found in the backplate and the spinner has worn bolt openings. The wear is most likely from an imbalance causing a vibration or harmonic. The spinner will need to be replaced. Corrosion was found on the blades which needs to be sanded and repainted.

The propeller is finally finished and installed! It took a little over two weeks and we finally brought her home on 9/18/2021. The prop looks brand new now.
