Rotorcraft: Common Theme Accidents
Accident Common Themes apply across the entire spectrum of accidents, and provide insight into relationships between seemingly disparate accidents. Common Themes allow identification of causes or accident factors that are independent of the type of accident, or the related threats.
Rotorcraft: Rotorcraft Life Cycle Accidents
A helicopter passes through many stages in its "life." Design and manufacturing create the product, which is then delivered to an individual or an operator and put into operational service. The majority of a helicopter's life cycle is spent in the Operational realm. During a helicopter's life however, periodic maintenance must be performed, and occasionally repairs and alterations occur. All of these elements can, and have, contributed to accident occurrences, and those contributions are addressed in this library.
