NTSB Narrative Summary Released at Completion of Accident
The Piper PA-30, Twin Comanche departed on a local multi-engine training flight. A few minutes later, it impacted water. Several witnesses observed the airplane and reported different airplane actions prior to impact. Examination of the airplane revealed that when it contacted the water, it was in a near flat attitude, rotating nose left, with the right wing lower than the left wing. Metal distortion was found on the tip tanks and outboard sections of both wings that was consistent with the left wing moving rearward, and the right wing moving forward, at the time of impact. The tip weight on the rudder was bent over to the right. Both engine mounts were deformed to the right. Damage to both propellers was consistent with the propellers in the governing range, at or near the same power setting, and not feathered. There was no evidence of a pre-existing failure or malfunction with the airplane or engines.
NTSB Probable Cause Narrative
The flight instructor's failure to maintain airplane control, which resulted in an uncontrolled collision with water.
