In rare situations where fuel samples cannot be taken who can authorize a waiver?

• A. Executive Officer
• B. Commanding Officer
• C. Maintenance Officer
• D. Flight Engineer

Answer: (A)

When fuel sampling cannot be performed, the person who can authorize a waiver is the Executive Officer. The Executive Officer acts as the Commanding Officer’s representative and has the authority to approve deviations from standard procedures in situations where delaying due to lack of samples would impact mission readiness or safety. Normally the Commanding Officer would grant a waiver, but in their absence the Executive Officer steps in to authorize it. The Maintenance Officer oversees maintenance programs, not waiver authority for sampling procedures, and the Flight Engineer handles in-flight fuel management and systems, not policy waivers.
