Already in use in thousands of single-engine aircraft, this propeller series is highlighted by McCauley's unique one-piece, oil-filled hub with threadless blade retention. That means greater dependability, coupled with low cost and high performance.
A full line of aluminum fixed pitch propellers for single - engine aircraft provides maximum performance -and minimum operating costs.
Product enhancements that were specifically developed for full-feathering propellers - like the oil-filled hub and threadless blade retention - have become standard, not just on these models but also on our constant speed models, for the lowest operating costs with high performance and reliability.
McCauley spinners are more than cosmetic attachments. They reduce drag by streamlining airflow. That means improved engine cooling and ram-air induction. Of course, they help make any aircraft more attractive and they're available in natural, polished aluminum and matte black finishes.
McCauley governors deliver precision control - in any flight condition. By hydraulically adjusting the blade angles, governors monitor and control engine speed. The result: quick response and greater RPM stability. In addition to governors, McCauley provides other innovative control systems including synchronizers, synchrophasers and accumulators.
McCauley electric de-ice systems are effective, efficient systems that come with slip-rings, brush-block assemblies, wire harnesses, boots and timers. Fluid anti-ice systems are also available with the same reputation for quality and performance.
