The plane, dubbed Ed Force One, was tethered to a truck at the Santiago International Airport and was being moved to be refueled and prepped for the next flight.
"On moving, the steering pin that is part of the mechanism that connects the ground tug to the aircraft seemingly fell out," the heavy metal band posted on its website. "On making a turn the aircraft had no steering and collided with the ground tug, badly damaging the undercarriage, two of the aircraft's engines and injuring two ground tug operators."
Neither Iron Maiden nor its 20 tons' worth of equipment were on board Ed Force One at the time.
The band posted an update on the condition of the Chilean airport workers who were injured stating that they "will make a complete recovery."
