Fact Sheet – Commercial Aviation Safety Team

For Immediate Release

The nation’s impressive commercial aviation safety record is due in part to the aviation industry and government voluntarily investing in the right safety enhancements to reduce the fatality risk in commercial air travel in the United States. The work of the Commercial Aviation Safety Team (CAST), along with new aircraft, regulations, and other activities, reduced the fatality risk for commercial aviation in the United States by 83 percent from 1998 to 2008 – and is continuing to do so.

Looking Ahead

Since its inception in 1998, CAST has evolved beyond the “historic” approach of examining past accident data to a proactive approach that focuses on detecting risk and implementing mitigation strategies before accidents or serious incidents occur. In 2010 CAST set a new goal: to reduce the U.S. commercial fatality risk by another 50 percent by 2025.

The transition to prognostic safety analysis requires greater emphasis on acquiring, sharing, and analyzing aviation safety data from across the aviation community. CAST is leveraging the data to identify emerging and changing risks and proactively adopting voluntary safety enhancements to mitigate the risks.

Voluntary programs such as the Aviation Safety Action Program (ASAP), Flight Operational Quality Assurance (FOQA) program, and Air Traffic Safety Action Program (ATSAP) are providing air carriers and the government insight into millions of operations, so potential systemic safety issues and trends are identified.

The Aviation Safety Information Analysis and Sharing (ASIAS) program connects a wide variety of safety data and information sources across industry and works closely with government-industry safety teams like CAST to monitor known risks, evaluate the effectiveness of deployed mitigations, and detect emerging risks. ASIAS is evolving but has matured to the point that the FAA and industry can now leverage voluntarily provided safety data representing 99 percent of U.S. air carrier commercial operations.

Safety mitigations strategies identified by CAST are voluntarily implemented by its community. Over the years, CAST had adopted more than 100 safety enhancements, with several based on information derived from non?accident data.

CAST Is Focused

CAST has developed an integrated, data-driven strategy to reduce the commercial aviation fatality risk in the United States. CAST identifies precursors and contributing factors to ensure resources address the most prevalent categories of risk that pose the greatest threat to loss of life. The group has reduced the fatality risk in commercial aviation by focusing resources on the following risk areas:

  • Takeoff Misconfiguration
  • Runway excursions,
  • Airplane State Awareness
  • Midair collisions,
  • Controlled flight into terrain,
  • Approach and landing accidents,
  • Loss of control,
  • Runway incursions,
  • Weather,
  • Turbulence,
  • Icing, and
  • Uncontained engine failures.

How CAST Works

CAST uses a disciplined, data-driven, focused approach to:

  • Analyze safety data/information,
  • Identify hazards and underlying contributing factors,
  • Develop specific safety enhancements to address risk,
  • Voluntarily implement cost?effective safety enhancements,
  • Track implementation and continuously monitor the effectiveness of the safety mitigations, and
  • Use knowledge gained to continually improve the aviation system.

CAST charters joint government and industry working groups for analysis of the systemic safety issues in commercial aviation. The groups leverage data from ASIAS to understand the underlying contributing factors and develop mitigation strategies.

Senior-level safety officials from CAST organizations meet regularly to oversee the activities of the following working groups:

Joint Safety Analysis Teams (JSATs)

JSATs perform in-depth analysis of particular safety issues. A JSAT examines the sequence of events leading up to each studied event and then identifies ways to mitigate potential precursors and contributing factors. The intervention strategies are then evaluated for their potential effectiveness.

Joint Safety Implementation Teams (JSITs)

JSITs determine the feasibility of the intervention strategies identified by the JSATs.  Each JSIT then develops and recommends a detailed action plan for industry and government to implement recommended safety enhancements based on those interventions with the highest effectiveness and feasibility.

Joint Implementation Measurement Data Analysis Team (JIMDAT)

The JIMDAT manages the CAST master safety plan. It monitors the implementation and effectiveness of the deployed safety enhancements, and recommends modifications and changes to CAST’s safety portfolio. The JIMDAT, in conjunction with ASIAS, also identifies gaps and emerging risks as well as additional areas of study. 

Global Strategy

Although CAST focuses on operations in the United States, CAST encourages government and industry partnerships to improve safety throughout the regions of the world.

Aviation is an international business. Accident rates and causes vary by region and do not lend themselves to “cookie-cutter” solutions. With that in mind, CAST coordinates with the International Civil Aviation Organization (ICAO), Flight Safety Foundation (FSF), International Air Transport Association (IATA), European Aviation Safety Agency (EASA), and other organizations. CAST has established links to other safety initiatives, such as the European Commercial Aviation Safety Team (ECAST), ICAO Regional Aviation Safety Groups (Pan American (RASG–PA), Asia Pacific (APAC), and Middle East (MID)), ICAO Coordinated Development of Operational Safety and Continuing Airworthiness Program (COSCAP) initiatives, and other regional safety programs. CAST representatives share CAST SEs that offer mitigation strategies for top fatality risk areas within the region. Representatives work with regional workgroups to adapt CAST solutions for implementation within the region. The CAST government?industry partnership model and its analytical methodologies are being adopted by safety teams around the world.
