What is the primary purpose of a CASS bench?

The primary purpose of a CASS (Consolidated Automated Support System) bench is to simulate aircraft functions for Weapons Replacement Assembly (WRA) and Shop Replacement Assembly (SRA) testing. This system is used to perform tests on various aircraft components without having to remove them from the aircraft. It can replicate the environmental and operational conditions that these components would experience during actual flight or operation, allowing maintenance personnel to determine if the components are functioning correctly.

By using the CASS bench for testing, technicians can efficiently diagnose issues and confirm the readiness of components, ensuring that they meet performance standards before reinstallation on the aircraft. This contributes to the overall safety and effectiveness of aviation operations, as it reduces the possibility of component failure during flight.
