WZL1 uses the following Non-Destructive Testing (NDT) methods that allow for detecting both surface and subsurface defects:
- Optical diagnostics – endoscopic inspections inside engines and accessories, with a capacity to record the results in the form of photographs and video;
- Magnetic Powder Tests (MT) – inspection on a magnetic bench in UV light that allows for detecting both surface and sub-surface defects;
- Penetration Tests (PT) – inspection by means of the portable fluorescent method, conducted under a fume hood or on aircraft to detect surface defects;
- Eddy Current Tests (ET) – inspection by means of a portable flaw detector, allowing for detecting both surface and sub-surface defects.
