Standard Operating Procedure (SOP) for Preparation of an Operation & Configuration Control Plan (OCCP) of "Category B" Pressure Vessels/Systems

This Standard Operating Procedure (SOP) describes the requirements and methodology for preparation of an Operation & Configuration Control Plan (OCCP) as required by JPR 1710.13 to assure safe ground pressurization and pressurization during aircraft operations of “Category B” Pressure Vessels/Systems (PV/S) at Johnson Space Center (JSC), Ellington Field (EFD) and associated NASA spaceflight/aircraft operations facilities.

An OCCP is a written assessment showing that a “Category B” PV/S is safe for ground pressurization and pressurization during aircraft operations, within the bounds established by the OCCP.
