Following three consecutive good landings, the instructor made the decision that his student was ready to undertake her first solo flight.
皇冠体育app weather was fine, with a surface wind from 220掳 at 9 kt. 皇冠体育app student was briefed to fly a single circuit on Runway 20, a 900 m hard runway. 皇冠体育app circuit was observed by the student鈥檚 instructor, watching from the ATC control tower. He reported that it appeared satisfactory until the point of landing, when the aircraft bounced a number of times. 皇冠体育app student decided to abandon the landing attempt and successfully flew a go-around manoeuvre.
On the second landing attempt the aircraft again bounced a number of times and appeared to enter a Pilot Induced Oscillation (PIO) for a time, before the student pilot was able to bring the aircraft under control on the runway. She was instructed to taxi clear of the runway and await assistance. It was subsequently established that the aircraft鈥檚 propeller and tail skid had struck the runway surface.
