The aircraft was landing towards the south-east on a sealed runway, with a 10-knot southerly wind blowing. Toward the end of the landing roll the pilot experienced difficulty in keeping the aircraft centred on the runway, with the result that it veered off the runway and nosed down in the soft ground off the sealed area. The propeller and engine area were damaged. The pilot reported that the left main tyre had deflated, probably because of the tyre not rotating during the landing. He considered that he had held his heels too high on the rudder controls, inadvertently applying brake to the left wheel during the landing flare and initial roll.
