Labyrinth rings/pins belonging to a particular type of aeroengine were sent to the laboratory for analysis. Examination revealed presence of fatigue crack in the pins from all the three engines. Fatigue cracks were found to have initiated at the deformation marks at about 4.5 mm from the pinhead. It appears most probable that these depression marks were formed by hot deformation at the disc/Labyrinth interface due to axial movement of the labyrinth ring.
