Radiography

Radiographic Examination (RT) is a Nondestructive Testing (NDT) method that examines the volume of a specimen. Radiography uses X-rays and gamma-rays to produce a radiograph of a specimen, showing any changes in thickness, defects (internal and external), and assembly details to ensure optimum quality in your operation.

Aircraft Preparation

Due to the hazardous nature of radiographic radiation, it is necessary to isolate the aircraft and keep unauthorized personnel at a safe distance. The aircraft may be defueled and must be properly marked with warning signs or roped off. In most instances, no disassembly of the aircraft will be required. The X-Ray tube must then be positioned. The individual inspection requirements will generally dictate the configuration and attitude of the aircraft

Radiograph Interpretation

The most important phase of radiography is interpreting the exposed film. The effort of the whole radiographic process is centered in this phase. Defects or flaws, which are overlooked, not understood, or improperly diagnosed, can jeopardize the reliability of the material. A particular danger is the false sense of security imparted by an inspection approval based on improper interpretation. At first impression, radiographic interpretation may seem simple, but a closer analysis of the problem soon dispels this impression.

Only qualified radiographic personnel should attempt to interpret radiographic films. However, the qualified reader must understand the necessity of maximum film interpretation due to increased structural complexity and the differing failure characteristics of new materials. Further, the radiographic reader must possess knowledge of aircraft and engine structures.
