Incident Overview
An instructional flight was conducting practice maneuvers involving an engine-out approach to landing. During the approach, the student pilot did not extend the landing gear. The air traffic control tower requested that the pilot verify the gear position ('verify gear down'). In response, the flight instructor initiated a go-around while the aircraft was on short final approach.
Sequence of Events
Despite the go-around attempt, the aircraft settled and touched down with the landing gear still retracted. The landing occurred on the grass area adjacent to the runway. The impact caused damage to the propellers and the underside of the aircraft hull.
Examination Findings
The flight instructor reported that the engines failed to respond during the go-around. However, a post-accident examination of the engines conducted by an FAA airworthiness inspector revealed no evidence of preimpact malfunction or failure. The inspector's findings indicated that the engines were capable of normal operation at the time of the accident.
