The Super Cub’s approach to Eshott’s Rwy 01was normal. After touchdown the aircraft decelerated suddenly, veering to the right and tipping onto its nose before almost immediately coming to a halt, angled at about 45° off runway centreline.
The speed of events was such that the pilot was unclear what had happened, but on leaving the cockpit he saw that the left wheel had shed its tyre and tube during the landing run and that the brake pipe had been severed.
Since the aircraft was equipped with heel brakes, which require the pilot to move his feet slightly backwards before application, he did not think he touched down with the brakes applied, but may have applied some braking once on the ground. This may have caused the aircraft to swing to the right, given the damage inflicted to the brake pipe.
The Grove disc brake modification fitted on this aircraft routes the pipe to the brake caliper in such away that it passes below the disc, rendering it vulnerable to damage once the tyre has deflated.
