Summary Aviation is one of the know‐how spheres containing a great deal of responsible sub‐assemblies, in this case landing gear. The necessity for reducing production cycle times while achieving better quality compels metrologists to look for new and improved ways to perform inspection of critical structures. This article describes the ability to determine the shape deviation and location of defects in landing gear using coordinate measuring machines and laser ultrasonic with high‐speed scanning. A nondestructive test is the basis for monitoring microcrack and corrosion propagation in the context of a damage‐tolerant design approach. This article presents an overview of the basics and of the various metrological aspects of coordinate measurement and a nondestructive testing method in terms of high‐speed scanning. The new test method (laser ultrasonic) promises to produce the necessary increase in inspection quality, but this is limited by the wide range of materials, geometries, and structure aeronautic parts used. A technique combining laser ultrasonic and F ‐ SAFT ( F ourier‐ S ynthetic A perture F ocusing T echnique) processing has been proposed for the detection of small defects buried in landing gear. The experimental results of landing gear inspection are also presented. SCANNING 34: 387‐394, 2012. © 2012 Wiley Periodicals, Inc.
