Explains the coding system for propeller hub designations and their modifications.
Details the designation system for propeller blades, including twist and sense of rotation.
Details installation of safety steps between magnetic valve plug and power supply.
Describes reverse activation using a microswitch in the cam box for negative thrust.
Explains reverse activation with a guarded switch, requiring reduced RPM before activation.
Details tightening sequence, torque values, and safety wiring for flange bolts.
Details functional checks for propeller pitch and RPM response, including bleeding air.
Describes checking governor function by adjusting power lever and manifold pressure.
Details testing the reverse system, checking beta function, reverse thrust, and indicator light.
Describes checking piston lock engagement by monitoring RPM increase and reverse function.
Details checking the startlock for seaplanes, including engine shutdown and restart procedures.
Mandates performing a test flight after installation and checks.
Describes governor operation, static RPM limits, RPM changes, and effects of oil pressure failure.
Specifies cycling the propeller at least twice before flight for system flushing.
Details reverse system checks during taxing, including engine oil temperature and reverse capability.
Explains how to achieve feathering at 1500 RPM and the procedure for unfeathering.
Describes reverse mode for ground operation only, with warnings about oil temperature and engine cooling.
Details daily checks for blades, spinner, cracks, erosion sheath, PU-strip, and oil leaks.
General inspections according to Aircraft Maintenance Manual or 100 flight hours.
Instructs to remove spinner, check for cracks, and measure blade shake.
Details permissible damage types on erosion sheath: cracks, dents, blisters, erosion, lightning strike.
Covers inspection and repair of blisters and delaminations on blades.
Describes repair of crunched trailing edges with 5-minute Epoxy, avoiding moisture ingress.
Instructs to inspect for lightning strike indications and send a report to the manufacturer.
Explains overspeed/overtorque conditions and refers to TCDS and engine specific limits.
States corrective action is based on severity and duration of overspeed or overtorque.
Requires propeller disassembly and inspection of various components following overspeed.
States overhaul must be performed according to the appropriate overhaul manual for overspeed/overtorque.
Instructs to remove propeller from service if corrective action requires scrapping.
Describes manufacturer repair for blades if 85% remain crack-free; replacement options.
Covers dynamic balancing procedures, required equipment, and acceptable imbalance limits.
Outlines pre-balancing inspections after reinstallation on the aircraft.
Troubleshooting for low static RPM, identifying if governor or propeller limits engine speed.
Remedy for low static RPM using pitch stop rods and warnings about rod adjustment.
Diagnoses slow or no pitch change due to blocked oil lines, sludge, damaged mechanism, or corrosion.
Lists causes for slow/no reverse like high temperatures, leakage, low pressure, wiring damage, or sticking blades.
Troubleshoots failure to reach positive pitch after reverse, possibly due to sticky valve.
