ABSTRACT:
INTRODUCTION
Commercial and military aircraft are being pushed beyond their anticipated lifespans and takeoff-landing cycles, resulting in an emphasis on improving upon current inspection methods. Certain existing metal inspection methods require the use of harsh chemicals and extensive surface preparation, which often involves removing the paint or coating before thoroughly cleaning the inspection area. The case study that will be presented showcases an updated eddy current array procedure. This technique uses the latest advances in eddy current array (ECA) technology to improve the probability of detection of cracks, reduce inspection time, and eliminate the need for chemicals and paint and coating removal. This case study focuses on the time-saving and environmentally friendly aspects of this ECA technique.
