equipment in the vicinity of the postulated impact, the analysis should proceed to

the next step.

Inputs:

The structural screening guideline. (Defined)

Mass (for aircraft and aircraft engine) and speed data for the

candidate aircraft categories/subcategories identified in Section 3.2.

(Defined partially in References 1 and 2 of Chapter 5)

Structural design information for the facility. (Available from existing

facility design documents)

A list of building-supported equipment whose failure could result in a

release (safety-related equipment) and its locations. (Available from

existing facility safety analyses)

The location of hazardous material within the facility and accident

scenario information. (Available from existing facility design,

operation, and safety analysis documents)

Outputs:

A list of impact locations and/or aircraft categories/subcategories that

can be screened out from further evaluation.

Structural Evaluation. The structural response evaluation step consists of

3.3.2

determining the type and extent of damage (local damage, excessive structural

deformation, and/or SSC functional failure due to vibration) to the facility when

subjected to impacts from aircraft subcategories that were identified in the

previous step as contributing to an annual impact frequency greater than the

frequency guideline. The results of the response analysis are reported as the

damage status for systems and structures, including confinement barriers,

meaning the level of damage an aircraft causes. In the case of individual

components, the damage status is limited to operable/nonoperable. Each aircraft

subcategory may be represented by a surrogate aircraft design for the purpose of

structural response evaluation. This surrogate aircraft design provides design

parameters such as aircraft mass, mass distribution, impact velocity, cross-
