The Importance of Wing Spar Inspections
Applied Technical Services performs NDT wing spar inspections to keep client aircraft safe and in the air. The wing spar is an integral component that connects the wings to the fuselage. These fasteners each bear a great deal of the stress generated during flight, requiring both the strength and flexibility to keep the aircraft together. The repeated stress from flights completed throughout its service life can gradually weaken these components as material fatigue sets in, eventually causing fractures in the component — often appearing in bolt holes. If not caught early by a qualified inspector, these same forces can cause these cracks to propagate and undermine the wing spar’s structural integrity. To ensure the safety of this critical component and avoid wing separation, owners and operators take their aircraft to certified aviation inspection services like ATS to verify the condition of their wing spars.
ATS' Aviation NDT Capabilities and Qualifications
Our experienced aviation inspectors each maintain an NAS-410 certification to perform nondestructive testing (NDT) on a wide variety of subjects, including aircraft components. Beyond their expertise in visual inspection, they employ high-frequency eddy current (HFEC) testing to detect flaws as small as an eighth of an inch in subjects such as the wing spar. This powerful NDT method uses magnetic fields created by applying current to metallic objects in a specific way, allowing our technicians to find flaws on, and just beneath, the material surface. Our Marietta lab maintains an ISO 17025 accreditation to perform eddy current testing to the following specifications:
  • ASTM E1004, E703, E426, E376, E244, E243
  • ASME Section V Article 8
  • NAVAIR 01-1A-16-2
Our Marietta location also serves as an FAA-certified repair station (#HC4D227M), authorized to perform numerous NDT inspections — including eddy current — on client aircraft. Our capabilities make us a perfect fit to handle wing spar inspections.
