On the morning of the day of the accident the pilot flew for 35 minutes in a Victa aircraft during which he
was instructed in spinning. On completion of the flight in the Victa the instructor then gave dual instruction
in circuit and landings in the Cessna 150. At the completion of this period, the instructor authorised the
student pilot to make his first solo circuit. This circuit was satisfactory and the instructor then authorised
a second circuit. The approach for landing on this circuit was normal but at level off the aircraft ballooned
and then landed heavily, nosewheel first, and the nosewheel leg collapsed.
