Common failures & inspection points
Visual and ultrasonic NDT inspection - SAFT (Synthetic Aperture Focusing Technique) for volumetric testing in stress zones 'A' and 'B' of propeller blades to detect cavitation pitting, erosion patterns, and material loss
Eddy current testing, magnetic particle inspection, and dye penetrant inspection focusing on blade root transitions, sharp edges, and thick-to-thin material transitions where 90% of failures originate
Functional test of blade pitch response to control signals, pressure test of oil distribution box (System D-F or D-M), inspection of hydraulic seals and intermediate shafts for leakage, verification of feathering capability if equipped
Visual surface inspection for corrosion pitting and discoloration, ultrasonic thickness measurements on blade and hub surfaces, inspection of sacrificial anodes (if present), verification of material certification (NiAl bronze vs stainless steel compatibility)
Pitch angle measurement at multiple blade stations using precision angle gauges, blade profile scanning for deformation, hub bore inspection for oversizing that indicates wear, verification of blade-to-hub bolt torque and integrity for ABP models
