N16CB
Maule M-5-220C
Witnesses described the airplane performing maneuvers that were described as aerobatic prior to impact about 35 degrees nose down, and provided a photograph taken shortly before the accident of the airplane in an inverted attitude. This airplane is not approved for aerobatic maneuvers. The fuselage, engine and propeller, and one wing were recovered from 90 feet of water for inspection by FAA inspectors. Records indicated that this airplane had recently had structural repairs to the steel tubing structure. Those areas, as well as the rest of the structure and wing and wing-strut attachment points were inspected by FAA inspectors and an NTSB investigator. No evidence was found of pre-impact structural failure of the airplane.
