National Academies' Panel on Evaluation of the Transport Airplane Risk Assessment Methodology
The U.S. Congress mandated the FAA to enter into an agreement with the National Academies of Sciences, Engineering, and Medicine (National Academies) to develop a report regarding the methodology and effectiveness of the Transport Airplane Risk Assessment Methodology (TARAM) process used by the FAA. TARAM is used to identify potential risks in currently operating airplanes, which will alert FAA officials if they need to take action to prevent potential accidents. The National Academies appointed an ad hoc committee of 12 members to undertake a study to evaluate the FAA’s TARAM process. This panel discussion will cover: Role and objectives of TARAM within the FAA’s overall safety oversight system; Assessment of the TARAM analysis process; Effectiveness of TARAM for the purposes of improving aviation safety; Recommendations to improve the methodology and effectiveness of TARAM as an element of aviation safety.
