This course will briefly introduce participants to US National Transportation Safety Board (NTSB) and International Civil Aviation Organization (ICAO) reporting requirements and review the primary historical causes of both US and international helicopter accidents. We’ll focus on aerodynamically oriented causes, including hover performance, downwind effects, forward flight transition, rotor system characteristics, high-speed phenomena, descent issues (such as the vortex ring state and autorotation), and ground issues (such as rollover and resonance). Component-fracture characteristics (for example, static fracture and fatigue) will also be briefly addressed, as will turboshaft engine factors, if time permits. Case studies will be included, and a notebook and CD will be provided.

Learning Objectives: By the conclusion of the course, participants will have learned:

  • Basic NTSB and ICAO reporting requirements
  • The primary historical causes of US and international helicopter accidents
  • Component-fracture characteristics
