Airmasters have the facilities, expertise and equipment to perform the required Shock Load Inspection.
We offer both in-house and mobile services.
Magnetic Particle Inspection is a non-destructive method for detecting defects in ferrous metals. A magnetic field created with AC or DC current is applied through the material, causing distortion in the magnetic flow at the surface or near-surface flaw.
Fine magnetic iron oxide particles, coated with a fluorescent dye and held in a suspension liquid, are attracted to the distortion in the magnetic field, in the area of the defect and will hold onto the edges of the defect to reveal it as a build-up of particles. The photographs show a Rotax 912 gears being viewed with ultra-violet light (black light) as part of the magnetic testing process.

Components are measured with precision instruments, to ensure they are within the tolerances specified by Rotax.
A Crankshaft inspection is carried out to check 'Cylinder Phasing'. This process is to measure if the crankshaft has been Twisted.
The Gearbox housing is checked for damage and a Dye Penetrant process is carried out to inspect for any cracks that may have been caused.
