Performance

Performance increases vary depending on individual aircraft and flight condition.

McCauley Propeller Systems is committed to designing, manufacturing, and delivering the finest propeller systems in the world. Introduced in 1989, the BLACKMAC line was the first mass production high performance propeller STC offered to the aviation industry. Pioneering the advancement of scimitar blade designs, solid one piece hubs, and internal steel split ring blade retention systems, McCauley has been setting

the industry standards for new propeller designs for over 60 years.
We at McCauley are very proud of the engineering and performance achievements we have reached with our line of piston & turbine propellers, and you will be too.
The following are just some of the reasons McCauley propellers are the finest in the world.

Improved take-off and climb performance

• Shorter take-off and landing distances and better climb

Quieter fly over and cabin noise levels

• Significant noise reductions when installing three blade propellers vs. two blade propellers and when installing four blade propellers vs. three blade propellers
• Most STC kits enjoy further noise reduction using the new generation scimitar blade design

Propeller design from original equipment manufacturer

• Replace your propeller with an STC designed and tested by McCauley Propeller Systems

Forged, single piece aluminum hub

• A superior engineering design over two piece hubs and external clamps that require numerous fasteners which are prone to service difficulties and Airworthiness Directives

Scimitar blade design

• A new generation of airfoil and scimitar blade designs which deliver the best performance and lowest noise levels available

Internal threadless blade retention system

• Designed with innovative engineering. Steel split rings installed inside the hub provide a superior blade retention system

Sealed hub design

• New generation of oil filled hubs for piston aircraft which provide constant lubrication and corrosion protection
• A design derived from our turbine propeller line, which enjoys over twenty years of AD free service excellence
• No annual servicing required beyond normal propeller care

Longest TBO available

• Piston applications up to 2400 hours or 72 calendar months (whichever occurs first)
• Turbine applications up to 6000 hours or 72 calendar months (whichever occurs first)

Industry leading warranty

• Standard three year warranty on McCauley owned STC kits extended to include McCauley supplied replacement parts for components found unserviceable due to manufacturing defects at first recommended overhaul

Industry leading customer support

• Toll free number connects you with technical support
• Worldwide network of factory authorized service centers and parts distributors
• 24 hour 7 day a week AOG service
