A pilot was wounded when SANParks' benefit planes went down in the Kingfisherspruit section of the Kruger National Park on Saturday afternoon.
The plane, Foxbat Bantam, had an anti-poaching mission when it dropped when poachers were suspected, Park Speaker, Ike Phaahla, said in a statement.
The first surveys show that the engine failed to get in hard.
"Details are still clear at this time, but no reports have been killed," he said.
"The pilot was evaluated by the doctor who lives in Skukuza and is taken to Nelspruit MediClinic to carry out a detailed survey after holding a gash to his head and small dimensions . "
Kruger National Park management manager, Glenn Phillips, said it was helpful that no-one was killed.
"We are grateful that the pilot is very good at this stage and we will give all the support to get through this amazing experience. We have our prayers with himself and his family and we & 39; pray that they will come back quickly. "
The purpose of the event is being investigated.
