Why This Manual Matters

Hartzell notes that this manual is intended to be the primary source of overhaul information for compact constant speed and feathering propellers, and is meant for use by propeller repair stations with personnel trained and experienced with Hartzell products. It supplies the manufacturer’s own torque values (Table 8-1, with the torque-wrench-adapter correction formula in Figure 8-1), blade tolerance limits (Table 8-2), and the check criteria used to determine whether a part is airworthy or needs repair — information that is not something a technician should be estimating.
