ETher VeeScan H -+ ETher . Eddy current array (ECA) is an assembly of single eddy current sensors or coils that are multiplexed in a certain order to obtain the required sensitivity. this will put a strain on the A&P-IAs. Mark E. Noftz, Andrew N. Bustard . DIFFERENT EDDY CURRENT TECHNIQUE 1. This inspection method is sensitive to small surface cracks, pits, subsurface cracks, corrosion on inner surfaces, and other flaws and is used to inspect parts of complex shape and size. Abstract Failure of any part of aircraft like wheel, turbine blades or aircraft lap splices is decidedly hazardous. The first use of eddy current for non-destructive testing occurred in 1879 when David E. Hughes used the principles to conduct metallurgical sorting tests. Our unique Eddy Current software allows us to evaluate the signal in multiple views and to accurately locate indication position. The FAA issued the far-reaching required inspection for thousands of these aircraft in response to the crash of a PA-28-200-R in Florida in 2018 that killed a young pilot on a checkride and the FAA examiner who was administering the test. Eddy current testing for aircraft is a tried and true method of ensuring the efficacy of metal components.

Defect and estimate corrosion loss on aluminum back surface This inspection procedure is designed to detect and estimate material thinning caused by corrosion on the back surface or back surface interface of aluminum structures, where one surface is accessible for setting the inspection probe. Crack detection Material thickness measurements (800) 333-3442. . Magnetic particle testing or visual inspection can be used to inspect aircraft wheels for potential flaws but leveraging eddy current array technology can offer more accuracy and simplicity. EDDYCON C is used for detection of surface cracks in various parts, cracks in holes and multilayered structures, surface and subsurface corrosion. "Eddy current is the least expensive, least invasive way of doing those tests, so we typically end up using it on a weekly basis." Meter-type instruments are often limited to aluminum airframe inspection with a set frequency and probe type, but more sophisticated impedance-plane units can be set to various frequencies for more applications. FAA-2020 . It is used to inspect parts of complex shape and size, gives immediate results and is widely used within the commercial, military, petrochemical, aircraft and aerospace industries.

A different coil display can be generated from data acquired with a single absolute coil. There are many different designs of eddy current probes, including flexible probes, padded probes or spring-loaded fingers. A few of these SIDs contain "requirements" to use Eddy Current Testing methods to detect cracks in . Eddy current inspections use an induction coil to generate electrical currents within conductors through a changing magnetic field. One of the major advantages of eddy current as an NDT tool is the variety of inspections and measurements that can be performed. Svitlana Priannikova Follow Sales Support Specialist, Ultracon-Service, LLC Advertisement An eddy current surface inspection array probe and method for detecting cracks and flaws in aircraft skin metal immediately surrounding rivets, without requiring rivet removal or manual scanning. By George Hopman April 1, 2022 In production, every aircraft structure component will undergo inspection by one of the primary NDT methods. Eddy current bolt hole inspections shall be performed in accordance with SAE ARP4402 or a written procedure specific to the aircraft being inspected and approved by the FAA. Western Aircraft offers a variety of services and inspection tools for non-destructive testing for your aircraft. It has become an important part of our nondestructive testing programs. These revisions became Section 2A and contain a whole slew of Supplemental Inspection Documents. It can be applied on Aluminium, Magnesium, Stainless Steel, titanium and almost all conducting materials. The System consists of the following components (assemblies): Table (frame) with a tray for wheels; More Info Ultrasonic Class NOW! Eddy Current Inspection of In-Service Aircraft Structure Eddy current inspections are particularly sensitive to crack, corrosion, and other conductivity changes within electrically conductive alloys. Changes in the flow path of these currents caused by discontinuities in the geometry or conductivity of the engine parts are detected by a receiving coil and identified as potential defects. There are issues that can arise that may not be able to be detected from a visual inspection or through magnetic particle testing. Our highly trained eddy current specialists analyze results using advanced software to differentiate relevant and non-relevant indications. It is helpful for detecting cracks in ferrous & nonferrous metals. Best NDT Inspection Technologies Pte Ltd provides a variety of Eddy current Testing services including High & Low frequency inspection for crack detection, Conductivity measurement & non conducting coating thickness on aircraft structures and components. The eddy current method is used for testing wings (fatigue cracks on the inside of wing boxes), bodies, wheel discs, engine parts (mainly - engine blades), rotors, axes, fasteners and holes (flaws in rivets, with the latter remaining in place), landing gears made of high-strength steel. -+ OKO NDT Eddy Current Rail Flaw Detectors -+ ETher - Aircraft Wheel Systems.
