performing the steps in this phase to the extent necessary to (1) understand the level of threat

posed by an aircraft crash and (2) provide sufficient information to allow the facility operator to

determine the need for (and type of) preventive and/or mitigative measures.

Another key aspect of the approach is that it must be integrated with the analysis of other

potential facility safety hazards. While the adverse effects of aircraft impact on safety-related

structures systems or components (SSCs) are being evaluated, the effect of the failure of

nonsafety-related SSCs (due to aircraft impact) on the safety-related SSCs, if any, should also

be evaluated.

The consideration of aircraft crash is not an independent safety assessment. This concept is

illustrated in Figure 1 by the inputs to the various steps from facility design, operation, and

safety documentation. The analysis of aircraft crash should not be addressed outside the

context of this other information.

The individual steps in the analysis are briefly described in this section. Each subsection

provides a list of inputs to and outputs from the analytical steps. The sources of inputs are

identified as follows:

Available - Information that should be available in other documents describing the

specific facility and its operation. Such information is generally not specific to

aircraft crash analysis and can be readily located by an analyst. Whenever

information is indicated as available, a potential source of that information is

indicated.

Defined - Information that exists in this standard, its supporting documents, or a

technical document referenced by this standard. Such information is generic in

nature (i.e., it is not a function of the specific facility being analyzed) and is

intended to be accepted as a given in the analysis (e.g., a constant to be used in

an equation).
