Aircraft Damage: Substantial
Defining Event: Dynamic rollover Injuries: 1 Serious, 1 Minor
Flight Conducted Under: Part 91: General aviation - Personal
Analysis
The pilot reported that, he was initiating a landing to a ledge. As the landing skids contacted the ground, the pilot felt the helicopter settle tail first. Startled by this, he abruptly raised the collective, unaware that he was holding forward cyclic input. As power was applied, the rear skids lifted off the ground first, creating a nose low attitude. The helicopter subsequently rolled over onto its right side substantially damaging the fuselage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot’s loss of helicopter control during landing, that resulted in a dynamic roll over.
Findings
Personnel issues - Aircraft control - Pilot
Aircraft - Lateral/bank control - Not attained/maintained

|
The National Transportation Safety Board (NTSB), established in 1967, is an independent federal agency mandated by Congress through the Independent Safety Board Act of 1974 to investigate transportation accidents, determine the probable causes of the accidents, issue safety recommendations, study transportation safety issues, and evaluate the safety effectiveness of government agencies involved in transportation. The NTSB makes public its actions and decisions through accident reports, safety studies, special investigation reports, safety recommendations, and statistical reviews.
The Independent Safety Board Act, as codified at 49 U.S.C. Section 1154(b), precludes the admission into evidence or use of any part of an NTSB report related to an incident or accident in a civil action for damages resulting from a matter mentioned in the report. A factual report that may be admissible under 49 U.S.C. § 1154(b) is available here.
