Common failures & inspection points
Hydraulic fluid level, viscosity and contamination check - critical for servo cylinder operation and pitch control reliability
Leak detection - inspect for hydraulic fluid leaks at servo cylinder connections, control rod seals and hub interface
Servo cylinder inspection - assess piston rod for wear, surface corrosion and verify full stroke operation range
Propeller blade pitch angle symmetry - verify uniform blade angles and pitch control mechanism response to actuation
Pitch control linkage and steering rods - inspect for wear, permanent deformation and ensure smooth articulation without binding
Bearing and lubrication systems - verify adequate grease/oil distribution and bearing condition to prevent seizure
Propeller hub and thrust surfaces - check for cavitation damage, corrosion and wear on feathering mode surfaces
Pressure relief and vent systems - inspect safety valves and air filtration to maintain system integrity and prevent air entry
