Current Nondestructive Inspection Methods For Aging Aircraft

Abstract : This report identifies and describes current methods used during the nondestructive inspection (NDI) of commercial transport aircraft for structural damage. The six most prevalent NDI methods identified are visual, eddy current, radiography, ultrasonic, penetrant, and magnetic particle. The physical principles, generalized performance characteristics, and typical applications associated with each method are described. In addition, descriptions of specific airframe and engine inspection practices are also presented.
