AIR7522 Portable Controlled Contamination Area (CCA)

This SAE Aerospace Information Report (AIR) provides guidelines for the design of portable Controlled Contamination Areas (CCAs) that can provide localized environmental control when processing a repair at the airplane or in a hangar environment. The use of a portable CCA may result in a better quality repair.

The use of a portable CCA may assist in achieving the environmental requirements for bonded repairs specified in an approved repair procedure. This provides an option to accomplish a repair on nonremovable structure or difficult to remove components.
