Fluid (slinger-ring) anti-icing and electrical (heater-boot) de-icing, and the anti-ice vs de-ice distinction.

Blade inspection and dressing of nicks, tracking and balancing, blade angle and functional checks, and shock-load inspection.

Corrosion protection, storage position, wooden-propeller care and de-preservation.
