The Major Finding. The recommended safety management process should improve the ability of the FAA/AIR, manufacturers, and operators to take corrective action based on incident data before an accident takes place and to set priorities based on assessments of current and future risk.

In addition, they may already have systems in place to collect the data needed for comprehensive safety management. A missing element in the current safety management process is a widely accepted risk analysis system or methodology, which is necessary to allocate resources appropriately and to define timely and effective corrective action.

From page 31... ...
In this environment, developing a comprehensive and accurate understanding of system malfunctions is difficult. Yet such an understanding is essential for the development of a proactive safety management process that accurately predicts risks and identifies corrective action before an accident takes place.

airlines had established FOQA programs, the FAA sponsored a study of FOQA programs used by foreign airlines. This study determined that "the appropriate use of FOQA data by airlines, pilot associations, and aircraft and equipment manufacturers would result in a significant improvement of flight safety by identifying operational irregularities that can foreshadow accidents andincidents" (FSF, 1992~.

The most suitable type of DBMS currently available is the object-relational DBMS. RISK ANALYSIS An effective safety management process should include risk analysis to provide a sound basis for risk management, which involves making decisions and taking action to reduce risks and, in the context of this study, to improve safety.

For example, professional pilots may believe that airlines have overestimated the costs of taking corrective action, which would lower its estimated cost-effectiveness, or decision makers and the public at large may not agree on the relative importance of expected utilities. Risk Analysis and the Air Transport Industry The committee met with aircraft manufacturers (Boeing and Airbus)

In short, risk management boils down to choosing the best available alternative, without regard to alternatives that are not available (Derby and Keeny, 1981~. The risk management/action function of the recommended safety management process is directly dependent on the risk analysis function for determining probabilities and costs.

From page 37... ...
The committee believes that the safety management process recommended in this report would help shift the focus of incident and accident investigations away from the question of who is to blame. Instead, the process would focus on identifying corrective action to prevent similar problems and their consequences.

From page 38... ...
An important aspect of the recommended safety management process is a comprehensive FOQA system, such as BASIS, for collecting data from automated flight data recorders, maintenance reports, incident and accident reports, etc. APPROVED DESIGN ORGANIZATIONS With few exceptions, existing legislation and regulations do not require applicants for type certificates, amended type certificates, STCs (supplemental type certificates)
|
From page 39... ...
Require ADOs and holders of production certificates to collect and analyze relevant safety data received from operators and to define corrective action in the event unsafe conditions are detected. Require applicants for design approvals to either hold an ADO certificate or employ the services of an ADO.
