What must be produced before making adjustments to a member's flying hour totals?

The correct choice is the source document, as it serves as the essential basis for ensuring accuracy in a member's flying hour totals. A source document typically provides the primary records and evidence needed to substantiate the flying hours accrued. This document can include details such as flight logs, training records, and other official paperwork that verifies each hour flown.

Before any adjustments can be made, this foundational documentation must be reviewed to confirm what the actual flying hours are. This step is crucial in maintaining integrity within the record-keeping process, as adjustments made without verification from a reliable source could lead to errors, mismanagement of resources, and potentially impact operational decisions.

While an audit report may be useful for overall assessments and a supervisor's report might provide recommendations or validations, they do not replace the need for initial data from source documents. A final tally summarizes totals but cannot be derived accurately without first establishing verified numbers from source documents. Therefore, producing and examining a source document is a fundamental requirement prior to making any adjustments to flying hour totals.
