What should a pilot-in-command do if they deviate from any rule in 14 CFR part 91?

When a pilot-in-command deviates from any rule outlined in 14 CFR part 91, it is essential to ensure compliance with regulatory requirements. The correct action in this scenario is to send a written report of the deviation to the Administrator upon request. This requirement is in place to maintain a clear record of any deviations, which helps regulatory bodies monitor safety and ensure accountability within aviation operations. Documenting such deviations allows for a better understanding of the circumstances surrounding the incident, contributing to safety improvements and potential future regulatory changes.

In contrast, while emergencies may justify deviations, the protocol mandates documentation and accountability afterward. Notifying passengers may be necessary from a communication standpoint, but it does not fulfill regulatory requirements. A verbal report to air traffic control is important for immediate safety concerns but does not replace the formal requirement of a written report if requested. Overall, the emphasis on sending a written report helps uphold safety standards in aviation by providing a transparent account of deviations and their justifications.
