Aviation Safety Analysis and Sharing (ASIAS)
Vivek Sood, Government Co‐chair, JIMDAT & IATFAA Technical Advisor, Vulnerability Discovery and Safety Measurement
In the United States, our focus was set by theWhite House Commission on Aviation Safety and the National Civil Aviation Review Commission (NCARC)
1.1 . . . Reduce Fatal Accident Rate . . .
• . . . Strategic Plan to Improve Safety . . . • . . . Improve Safety Worldwide . . .
CAST Goal
CAST came together in 1997 to form an unprecedented Industry-Government partnership. Voluntary commitments, consensus decision-making,
data-driven risk management, implementation-focused. Goal:
Reduce the U.S. commercial aviation fatality risk by at least 50 percent from 2010 to 2025.
New
Reduce the U.S. commercial aviation fatal accident rate by 80 percent by 2007.
Original
CAST brings together key stakeholders to cooperatively develop and implement a prioritized safety agenda.

Fatality Risk – (Severity)
• A collaborative Government-industry initiative on safety data analysis and sharing
• A risk-based approach to aviation safety, identifying and understanding risks before accidents or incidents occur
• Timely mitigation and prevention
What is ASIAS?
Stakeholder Organizations must uphold the Core Principles.
InformationSharing
Collaborative effort inclusive of all Stakeholder Organizations and balancing the interests of
those participants.
Participation is entirely voluntary. All agree to voluntarily implement
mitigations.
Data is used solely for the advancement of safety
Securing resources to support the development and
operations plans.
Reach and maintain consensus with all relevant employee
groups on sharing any data before it is provided
to the program.
Establish appropriate protocols to protect the identity of the reporter/organization from
disclosure and ensure nonpunitive use of data/information
(Government and industry).
Key Steps
Build trust through demonstrating value from
information sharing.
Focus on a specific issue to highlight benefits of the program, coupled with
mitigating activities.
Establish a small group of senior executives from Government
and industry to champion the program.
Leadership needs to be the catalyst for change.
Need to be engaged across the spectrum.
Community outreach is vital.
Need engagement with technology partners to inform IT investments appropriate to
system needs.
Ensuring Success
ASIAS Is Governed by Formal PrinciplesVoluntary submission of
safety-sensitive dataData used solely for advancement of safety
Transparency – knowledge of how data are used
Data used solely for advancement of safety
Procedures & policies established through
collaborative governance
Analyses approved by an ASIAS Executive Board
Carrier/OEM/MRO data are de-identified

Safety insights gained from ASIAS are invaluable, as it is not possible to achieve them through other means and gives us the ability to—
• Identify systemic risks.• Detect the degradation of
safety barriers.• Monitor the effectiveness of
deployed mitigations. • Understand the impact of changes in
the aviation system.
CAST has adopted 22 safety enhancements to address systemic risks based on non-accident data from ASIAS.
