A labyrinth ring and 55 pins pertaining to an aeroengine, which completed 741:29/242:02 hrs in service were sent to the laboratory for analysis. Dye penetrant examination revealed crack like indications in 9 pins out of the 55 pins at about 4-5 mm from the pin-head. Examination of these pins under the Scanning Electron Microscope revealed a circumferential deformation/depression marks at this location. Metallographic examination showed that out of these 9 pins, one pin had a fatigue crack of length of about 450 m.
