Which statement about IOR timing is true?

• A. PIC must fill within 12 hours.
• B. FAA receives IOR within 3 days.
• C. PIC must fill within 24 hours; company must forward to FAA within 10 days.
• D. No time limit.

Answer: (C)

Timing for IOR reporting centers on prompt, proper documentation and timely transmission to the FAA. The best statement reflects the standard requirement: the PIC must complete the IOR within 24 hours, and the company must forward it to the FAA within 10 days. This dual timeline ensures the pilot captures details while they’re fresh and accurate, while the operator provides a complete record to the regulator for safety oversight. The 24-hour window helps establish initial accountability and factual grounding, and the 10-day window gives the company time to compile a thorough report before it reaches the FAA. Choices that propose a 12-hour window, FAA receipt within 3 days, or no time limit do not align with these established reporting timelines and would hamper timely safety analysis.
