The pilot had flown from Archerfield to Surfers Gardens to pick up a passenger, and made a normal landing on strip 12. About 20 minutes later he was taxiing for takeoff on strip 12 when the nosewheel strut collapsed, and the propeller struck the ground. The ALA had only recently been reopened after having been closed for some time due to a soft wet surface. The nosewheel had entered a slight depression prior to the strut collapsing but the depression should not have been sufficient to overload the strut to the point of failure at normal taxiing speed. Examination of the nosegear showed that the metal to metal epoxy bonding which attaches the torque tube to the airframe end fittings had failed. This failure allowed the torque tube to rotate inside the end fittings, to the extent that all normal suspension action was lost. The nosegear strut assembly then folded upwards into the engine cowls, and the propeller struck the ground. The epoxy bonding had deteriorated to the extent that the load carrying capacity of the nosegear had been substantially reduced.
