Which document must include the reason(s) for exceeding the hours of service?

• A. TRO-Q
• B. TRO-4
• C. TRO-1
• D. TRO-5

Answer: (A)

When a crew goes beyond the allowed hours, the reason for the exceedance must be documented to provide a clear record for safety and regulatory review. The TRO-Q form is the document designated for recording hours-of-service exceptions and the explanations for why the limit was surpassed. Including the rationale on this form creates an auditable trail that supervisors and compliance officers can examine to assess fatigue risk and determine any needed corrective actions. The other TRO forms serve different reporting purposes and do not specifically capture the reasons for hours-of-service exceedance, so they don’t fulfill this requirement.
