McCauley Propeller Systems has a rich history that spans over 90 years. The company began in 1928 in a small shop on Howell Street, in West Dayton, Ohio, with about 18 workers.

In the 1930s and 1940s, McCauley produced wooden propellers. The company is noted for having invented the ground-adjustable, solid-steel propeller in 1941.

During World War II, McCauley manufactured 20,000 ground-adjustable solid-steel propellers. In 1946, the company invented the forged aluminum propeller.

In 1947, McCauley developed the first all-metal propeller for light aircraft. By 1967, the company was operating in a 160,000 sq ft factory, employing 230 workers, with an annual sales volume of about US$5 million.

The company continued to innovate, introducing propeller spinners and governors in the late 1960s. Between 1976 and 1978, Cessna planned to replace the McCauley factory with a new one, but ultimately decided to keep it at the Dayton International Airport.

By 1982, McCauley was producing not only propellers, spinners, and governors, but also wheels, brakes, and other accessories for aircraft. In 1986, Cessna, McCauley's parent company and principal customer, stopped producing propeller-driven aircraft due to product-liability lawsuits.

The company's fortunes changed in 1996 when the General Aviation Revitalization Act was passed, limiting aircraft manufacturers' product liability. Cessna resumed production of propeller-driven aircraft, using McCauley propellers, which boosted McCauley sales.

In 2021, McCauley's propellers were used on the first Beechcraft Denali single-engine turboprop, marking a significant milestone for the company.

McCauley Propeller Systems are built with high strength, corrosion resistant aluminum alloy, which provides a solid foundation for their propellers. This material choice is a key factor in their exceptional performance and durability.

Their precision engineering and manufacturing processes ensure that every propeller meets the highest standards of quality. You can trust that every McCauley propeller is built to last.

Here are just some of the key features and benefits of McCauley Propeller Systems:

McCauley propellers are built with high strength, corrosion resistant aluminum alloy, ensuring durability and longevity.

Their precision engineering and manufacturing process guarantees a high level of quality control.

McCauley propellers are capable of maximum takeoff and climb performance, making them ideal for aircraft that require exceptional power.

With the highest Time Between Overhaul (TBO) available anywhere, you can enjoy extended periods of trouble-free operation.

McCauley propellers also have the fewest Airworthiness Directives (ADs) in the industry, minimizing the need for costly repairs or modifications.

Here are some of the key benefits of McCauley propellers:

Full Feathering is a key feature in some aircraft propellers. This technology has been around for over 30 years.

McCauley's full feathering propellers were first introduced for reciprocating twin engine and turbine powered aircraft. They utilize design features found on constant speed models.

One of these design features is the oil filled hub, which has become a standard on all constant speed models. This helps to improve performance and reduce wear and tear.

Threadless blade retention is another feature that's become standard on all constant speed models. This design helps to make maintenance and repairs easier.

McCauley Propeller Systems have been setting the standard for innovative propeller design for over six decades. Their commitment to excellence has made them the go-to choice for many aircraft owners.

The company's engineering and performance accomplishments are truly impressive, with a line of piston and turbine propellers that continues to push performance to new limits. McCauley's family of propellers is incredibly diverse, yet remarkably durable.

McCauley Products have been setting the standard for innovative propeller design for over six decades. Their commitment to engineering and performance has led to unparalleled accomplishments in the industry.

McCauley's line of piston and turbine propellers continues to push performance to new limits. This is evident in their ability to meet the demands of various aircraft.

McCauley's family of propellers is as diverse as it is durable. Their products cater to a wide range of needs, ensuring that every aircraft that uses them can take advantage of their innovative design.

Spinners were introduced to the product line in 1957, and they serve both cosmetic and functional purposes.

They enhance aircraft appearance and looks on the platform, making them a great addition to any aircraft.

Spinners reduce unwanted drag by streamlining the airflow, which provides much improved engine cooling.

This is especially useful for aircraft, as it helps to keep the engine running smoothly and efficiently.

By streamlining the airflow, spinners also provide much improved ram air intake on aircraft.

At McCauley Propeller Systems, rigorous testing and evaluation are crucial to ensuring the reliability and performance of their propellers. Centrifugal load tests are required for propellers with detachable blades, which must be tested to twice the maximum centrifugal force they'll experience in operation.

The current standard for these tests is outlined in Section 35.35, but it has limitations. It only addresses the blade and hub retention capacity, without considering factors like composite materials or service degradation.

McCauley Propeller Systems takes a comprehensive approach to testing, going beyond the minimum requirements to ensure their propellers can withstand the demands of flight.

McCauley Propeller Systems has had a long history of leadership and innovation, with several key individuals playing a crucial role in shaping the company.

Ernest G. McCauley, the founder, was a pioneer in the aircraft propeller industry and held numerous patents on controllable propellers. He provided outstanding service to the United States government from 1918 to 1950.

In the 1940s, McCauley was voted out of power by a large board of directors he had recruited. He died in 1969.

Shop superintendent Vernon W. Deinzer was promoted to vice president for manufacturing in 1954 and became vice president and general manager in 1957. He remained as general manager of Cessna's McCauley Industrial division after Cessna acquired McCauley in 1960.

Vernon W. Deinzer was reassigned to vice president and general manager of Cessna's Aircraft Radio division in 1967. He was replaced by engineer and executive trainee John C. Dussault, who had previously worked as the technical services manager for commercial aircraft engineering at Cessna's Wichita headquarters.

John C. Dussault was among seven top McCauley division officials who accepted an early retirement offer from Cessna in 1982. He was replaced by Walter Voisard, who had previously been vice president and chief engineer of McCauley Industrial Corp.

Here is a list of some of the key personnel who have played a role in McCauley Propeller Systems:

The FAA has taken action to address a potential safety issue with McCauley Propeller Systems. They've issued a new airworthiness directive requiring the replacement of certain governors with eligible ones to prevent the installation of an unapproved variant idler gear bearing.

The directive was prompted by reports of the unapproved bearing, part number A-20028, which could be installed in the affected governors. This replacement is necessary to ensure the safety of the products.

The FAA has also proposed special conditions for a new McCauley Propeller System model, the 3D15C1401/C80MWX-X, which features composite blades. The existing airworthiness regulations don't cover this design feature, so the proposed special conditions aim to establish a level of safety equivalent to the existing standards.

The McCauley Propeller Systems Model 3D15C1401/C80MWX-X is a specific product that has special conditions attached to it. These special conditions are applicable to this model.

If you're looking to apply for a change to the type certificate to include another model with the same novel or unusual design feature, you'll be happy to know that these special conditions would also apply to that new model.
