This document covers the procedure for installing Airmaster blade assemblies into the propeller hub.

Each blade is matched to a specific hub port number, as configured when the propeller was statically balanced. The blade number is scribed on the cam plate at the base of each blade. Installers must ensure that blades are installed in the designated hub port configuration.

Installers must also ensure that the propeller hub and blade retention assemblies are correctly lubricated before blade installation. Excess grease in this region can create a hydraulic effect, which may prevent proper torque application and potentially cause damage to the propeller or engine.

Before locking the blade retention nut, installers must check that each blade is fully seated inside the hub. Improper blade seating can result in propeller imbalance, leading to potential damage to the propeller or engine. Recommended blade seating checks are provided in this document.
