McCauley 3-Blade Propeller C3D32S403

Description

You’re doing your pre-flight walk-around on a crisp morning, and you want to know your propeller is in top condition—that’s where the McCauley 3-Blade Propeller C3D32S403 comes in. This constant-speed propeller is designed for pilots operating single-engine aircraft who need reliable, precise RPM control across a range of flight conditions. The three-blade design balances efficiency and performance, and the constant-speed mechanism automatically adjusts pitch to maintain your selected RPM, reducing workload and optimizing power delivery whether you’re climbing out or cruising at altitude.

Before ordering, verify the C3D32S403 against your aircraft’s logbooks and type certificate data sheet—propeller compatibility is critical and model-specific. McCauley props are known for durability in general-aviation service, but installation, overhaul, and any modifications must follow the manufacturer’s instructions and your airframe’s maintenance manual. If you’re replacing an existing prop or evaluating an upgrade, confirm bolt patterns, hub type, and any governor or de-ice requirements your aircraft specifies. Reach out to our team with your tail number or aircraft type if you need fitment guidance.
