The accident happened at the privately-owned Peterborough Business Airport at Conington shortly before midday on
Saturday, February 27.
The pilot, believed to be a man in his 40s, suffered what is thought to be a serious leg injury and a cut face, and was taken to hospital.
A spokesman for the airfield said: “The incident was simplistic enough in that a student pilot lost control on a go-around, I understand, at the end of the runway and finished up landing on the cropped field adjacent.”
The Air Accident Investigation Branch said it had deployed a team to investigate.
The East of England Ambulance Service NHS Trust said it was called to the crash at around 11.30am, mobilising the Magpas air ambulance and paramedics on the ground.
A spokesman said: “They treated one patient - a man in his 40s who had suffered a suspected broken leg.
“He was taken by land ambulance to Peterborough City Hospital for further treatment. His injuries are not believed to be life-threatening.
