Under what condition is the aircraft or support equipment allowed to be released?

• A. Only after QA investigators and the MO are satisfied that the missing tools are not in the aircraft or equipment
• B. Immediately after search
• C. After flight test
• D. After next shift change

Answer: (A)

Before any aircraft or support equipment can be released, there must be formal confirmation that all tools are accounted for and none are left on board. This verification is done by QA investigators and the maintenance officer, who sign off only when they are satisfied that the missing tools are not inside the aircraft or equipment. This step protects against foreign object debris and potential in-flight damage or failure. Rushing the release after a search isn’t enough because a tool could be missed or hidden, and releasing after flight testing or after a shift change doesn’t address tool accountability at the point of release. The safe, correct condition is the sign-off confirming no missing tools remain on the aircraft or equipment.
