Helicopter Accident Investigation (HAI)

Course Description

The course examines the investigation of helicopter accidents to include processes used to determine the cause. The course includes interactive lecture, various case studies, examination of component wreckage in the classroom and helicopter wreckage examination in the laboratory. The course includes examination of helicopter rotor systems, controls, performance variables, flight hazards and material characteristics involved in helicopter operations and accidents. Although Aircraft Accident Investigation (AAI) is not a prerequisite, it is assumed that the attendee has either completed AAI or has some previous experience in aircraft accident investigation.

Objectives:  To provide concepts, practical techniques and methodologies essential to rotary wing aircraft accident investigation.

Who Should Attend:  Persons associated in rotary wing accident investigation including manufacturers, operators, associations, insurers, law enforcement, military and government agencies.
