The pilot had not flown for 10 months and had carried out a check flight with an instructor before conducting a session of solo circuits later that afternoon. The first three solo circuits were without incident. During the fourth circuit, shortly before the landing flare, the pilot was distracted by a radio message from the air/ground radio operator requesting his position. He then realised that the aircraft was high and slow and initiated a go-around. However, the aircraft bounced before climbing away.
During the subsequent landing the nose landing gear collapsed, having probably been damaged during the previous ground contact.
