What action must be taken when a pilot in command deviates from any rule in 14 CFR Part 91?

When a pilot in command deviates from any rule in 14 CFR Part 91, the appropriate action is to send a written report to the Administrator upon request. This is important because it ensures that deviations are formally documented and assessed by the FAA, allowing for the review of circumstances surrounding the deviation.

The need for a report emphasizes the regulatory framework designed to maintain safety in aviation. The FAA uses these reports to track potential patterns of non-compliance and address safety concerns. This process supports transparency and accountability within aviation operations.

In cases of deviation, the pilot is required to document the event only if requested by the Administrator. This policy allows for flexibility based on the nature of the deviation and the surrounding circumstances, focusing on a fact-based assessment rather than an immediate reaction to every deviation.

This process helps improve aviation safety by analyzing the reasons for deviations and applying lessons learned to prevent future occurrences.
