Description Four IPNGV screws from an aeroengine, which had completed 9800 hrs of flight, were sent to the laboratory for analysis. All the screws were found severely corroded/oxidized. The corrosion/oxidation products were found to contain substantial amounts of O, S among the other elements. A few tight cracks were also observed at the thread root regions. Since these cracks were very shallow, they could not be opened for further study. However, formation of theses cracks due to stress corrosion cracking cannot be ruled out.
