Which 781 version is used for COMSEC material installed on the aircraft?

• A. 781D
• B. 781A
• C. 781B
• D. 781C

Answer: (C)

Documenting the installation of sensitive COMSEC material on aircraft uses a specific 781 revision because the 781 series is organized to match asset type and security requirements. The version chosen for COMSEC items includes the exact data fields, custody signatures, and handling notes that policy requires for accountable, auditable control of cryptographic or security-sensitive equipment. Using that designated revision ensures you record the item’s identity (type and serial), its quantity, where it’s installed, and who is responsible for it, creating a clear custody trail from procurement through installation and any future inspections. If a different revision were used, important COMSEC-specific fields or controls could be missing, making it harder to prove compliance or perform audits. Other versions exist for different categories of equipment or updates to data fields, so they aren’t appropriate for COMSEC material installed on the aircraft.
