Propeller Alignment Check ensures the propeller is correctly aligned with the engine shaft to prevent vibration and wear.

Propeller Inspection involves examining blades, hub, and fasteners for cracks, corrosion, or damage to ensure safe operation.

Both checks are critical for maintaining aircraft performance, efficiency, and safety during flight.

Propeller Alignment Check:
Size: Varies by propeller diameter (typically 0.5m to 6m)
Grade: N/A (alignment tolerance ±0.1mm to ±0.5mm)
Viscosity: N/A
Buoyancy: N/A
Material: Laser alignment tools (aluminum/stainless steel), dial indicators (steel)

Propeller Inspection:
Size: Dependent on propeller dimensions (blade length, diameter)
Grade: Marine-grade (ASTM/ISO standards)
Viscosity: N/A (lubricants used: ISO VG 68-220)
Buoyancy: N/A (inspected in dry dock or water)
Material: Bronze, stainless steel, nickel-aluminum bronze, or composite materials
