Aerospace NDT Inspection / EASA Part-145


Due to our strategic alliance with AOG Inspection Ltd in the UK we are able to offer a wide and comprehensive expert service to our clients . 

Visual Inspection (VT)

Visual inspection, with or without optical aids, is the original method of NDT. Many defects are surface-breaking and can be detected by careful direct visual inspection.

Ultrasonic Inspection (UT)

Ultrasonic methods of NDT use beams of mechanical waves (vibrations) of short wavelength and high-frequency, transmitted from a small probe and detected by the same or other probes.

Magnetic Particle Inspection (MT)

This method is used for the detection of surface and near-surface flaws in ferromagnetic materials and is primarily used for crack detection of any shape or heat treated condition.

Eddy Current Inspection (ET)


In eddy current testing, a coil carrying an AC current is placed close to the specimen surface, or around the specimen.

Liquid Penetrant Inspection (PT)


Penetrant Inspection is one step up from visual inspection using visible red penetrants for small welded components to large vessels or sensitive fluorescent penetrants for high specification inspection such as the aerospace industry.

Radiographic Inspection (RT)

Radiography uses X-rays or gamma-rays to produce an image of an object on film. The image is usually natural-size.
