Because of the continuing problem of hardware changes, Apollo Program Director Samuel C. Phillips revised policies and procedures for control of changes for AS-503 and subsequent missions.

Level II Configuration Control Boards, said Phillips, would have authority to implement several categories of engineering changes: mandatory changes to ensure crew safety or mission success, changes that would substantially reduce workload or checkout time at KSC, and changes to improve the probability of launch and to reduce the possibility of launch delays or scrubs, based on engineering analysis and failure history. Phillips admitted that other essential changes might be needed that did not fulfil these criteria, but such "down-the-line" changes must be held to an absolute minimum, he told ASPO Manager George M. Low. All changes that affected deliveries or launch schedules, on the other hand, must still be submitted to the Level I CCB for approval before implementation. These revised procedures, Phillips believed, would produce the control of changes needed to ensure an operationally suitable Apollo space vehicle, yet allow the secondary-level CCB to exercise "tough and critical judgment" of the change decision process, to allow needed flexibility within the overall program.
