This is his normal procedure as he expects his student to be watching the runway. At a speed estimated by the pilot privacy data omitted at less than 20 mph, the nose gear retracted for unknown reasons. The student had estimated their speed at approximately 40 mph. Both pilots stated the neither of them touched the landing gear selector on the rollout. privacy data omitted Damage to the aircraft is to the propellers, engine and around the nose gear area. On-scene investigation by inspectors failed to find any mechanical problems with the landing gear of this aircraft. A retraction test is to be performed prior to releasing the aircraft for service.
