Abstract

A fractured quill shaft belonging to the speed governor assembly of an aeroengine along with an oil sample was received for analysis. Examination revealed that the quill shaft has failed by torsional overload. No metallurgical or mechanical abnormalities were responsible for the failure. The oil sediment was found to be in the form of metallic slivers and particles of varying sizes. The chemical composition of the sediment was determined by EDX analysis and it was found to be 90.1%Al-5.4Cu-0.7Mn-0.3Mg-1.2Fe-2.3Si.
