To help meet this demand for high quality, a continuing program far development and improvement of nondestructive testing methods is conducted by the Metallurgical and Non- destructive Teat Section, Quality Engineering Branch. Nondestructive testing is a family of methods for investigating the quality, integrity, properties, and dimensions of materials and components without damaging or impairing their serviceability. By detecting defects in early stages before engineering tolerances are exceeded, it is pos- sible to salvage parts through rework. This helps maintain a status of supportability and re- duces excessive procurement of new parts. Testing Methods The testing methods general- ly accepted by industry today are dye penetrant, eddy cur- rent, magnetic particle, ultrasonic, radiography, and visual. Inspection efficiency depends on matching the right testing method and hardware to the specific requirement. For example, eddy current testing can detect discontinuities in ferrous or nonferrous Ultrasonic inspection parts. utilizes high frequency sound waves as means of revealing flaws and corrosion defects, or the absence of them. Penetrant inspection uses penetrating liquid which seeps into cracks and reveals defects which otherwise would go undetected. If specific nondestructive methods are not available for particular needs, the Metallurgical laboratory often researches and develops inspection techniques, tests for adequacy, and writes test procedures for local and field inspections. These procedures are then incorporated into the applicable technical orders. To successfully assume this responsibility, specialists in the laboratory must have knowledge of the product, clear understanding of its intended use, and how defects would affect its service life. Inspect Tire One such method developed and implemented fleet wide is an ultrasonic inspection of the tire bead seat area in the outboard half of the main wheels with the tire and wheel assembly mounted on the aircraft. This inspection locates fatigue cracks in their initial stages prior to their progression to critical failure. This inspection results in a tremendous saving in wheel disassembly" and aircraft downtime. To carry out the best method of testing is a serious responsibility for every inspector. Tests must be applied with care and within exact standards, and interpretation of the test results must be accurate to pinpoint trouble spots. Therefore, all nondestructive test operators are trained, tested, and certified before accomplishing any tests. The trairv-inand certification program is accomplished by the Metallurgical laboratory.
