Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
CEN11CA303
The pilot reported that he was water-taxiing a fixed-float equipped helicopter in a right sideways direction when the helicopter rolled to the right, impacted the water, rolled inverted, and sank. The pilot, who was the sole occupant, was able to exit the inverted cockpit, inflate his life vest and swim to shore. The helicopter sustained substantial damage to the main rotor system, tail rotor, and fuselage. The pilot reported no preimpact mechanical anomalies with the helicopter. The characteristics displayed by the helicopter were indicative of it encountering a dynamic rollover.
NTSB Probable Cause
The pilot's improper use of the collective and cyclic control during taxi operations, which induced a dynamic rollover.
Full Narrative
The pilot of the fixed-float equipped helicopter reported he was water-taxiing in a right sideways direction when the helicopter rolled to the right, impacted the water, rolled inverted, and submerged. The pilot, who was the sole occupant, was able to exit the inverted cockpit, inflate his life vest and swim to shore. The impact caused substantial damage to the main rotor system, tail rotor, and fuselage. The pilot reported no preimpact mechanical anomalies with the helicopter. The helicopter's tendency to continue rolling when the critical angle is exceeded, as when one skid is caught on the surface, and the helicopter pivots around that point, is dynamic rollover.
