How often should a McCauley prop be overhauled?
every seven years
McCauley recommends that their fixed-pitch propellers be overhauled every seven years or 2,000 hours, while Sensenich only uses 2,000 operating hours as the TBO for their propellers. These overhauls are important, both for safety and performance.
What is the history of propeller?
The first versions of the propeller were derived from a rotating screw design, which was first invented by the ancient Greek scientist Archimedes in 200 BC. These early screws were used by ancient civilizations to lift water from wells with much less effort.
How often should a propeller overhaul?
five to seven years
Almost all propellers have time before overhaul (TBO) guidelines published by the manufacturer based on both the in-flight hours and calendar months that the propeller has been in service. They typically range from 1, 000 to 2,000 flight hours and five to seven years in service.
What are the 2 types of classifications of a propeller?

- Fixed-Pitch.
- Ground-Adjustable Propeller.
- Controllable-Pitch Propellers.
- Constant-Speed Propellers.
- Feathering Propellers.

What are the 4 types of materials used in propeller construction?
Material and Construction of Propeller The materials used for making marine propellers are an alloy of aluminium and stainless steel. Other popular materials used are alloys of nickel, aluminium and bronze which are 10~15 % lighter than other materials and have higher strength.
