Question: While walking the ramp one day you were staggered by the beauty of one airplane’s polished propeller blades. Is polishing an option for the propeller on your airplane?
Answer: Possibly. It is best to check with the propeller manufacturer to determine if polishing is acceptable. This is because to achieve the polished look, corrosion protection such as paint is often removed. According to a 2008 special airworthiness information bulletin, “Polished propeller blades are rarely an acceptable configuration”.
