Report No. ARL-TR-4033

Abstract: The U.S. Army Aviation and Missile Research Development and Engineering Center requested that the U.S. Army Research Laboratory develop and execute a program designed to evaluate the performance of nondestructive inspection (NDI) techniques over typical army aviation paint systems. Corpus Christi Army Depot performs the majority of the current maintenance and overhaul operations on army aviation systems. This facility would greatly benefit in throughput and in reduction of hazardous waste generated if the removal of the applied coating systems could be avoided. The objective of this work was to evaluate the effect of not removing the most common currently approved aviation coating system on the NDI cycles. The test plan and methodology was created in conjunction with and approved through AMSRD-AMR-AE-F-M.
