Elastomeric components are now used extensively on all modern helicopters. They are one of the main reasons for the vast improvements in performance and the increase in reliability these new aircraft exhibit. These components use leading edge technologies which are not always well understood by maintenance personnel and pilots, who are called upon to inspect them on a regular basis. Our experience has shown that too often, parts are removed prematurely due to misunderstanding of the construction and workings of these complex components. This session explains the construction, the function, the maintenance and the inspection of these various types of components.
