When must a pilot submit a written report after deviating from a regulation during an emergency?

A pilot is required to submit a written report after deviating from regulations during an emergency upon request. This procedure allows for flexibility in reporting, acknowledging that emergencies occur in high-pressure situations where immediate actions may be necessary for safety, and a formal report can be compiled later.

The rationale behind this is to ensure the pilot focuses on resolving the immediate situation and flight safety, rather than being preoccupied with documentation during a crisis. Reports are typically only required when authorities or regulatory bodies seek further information regarding the incident. This emphasizes accountability while also recognizing the intense and often chaotic nature of emergency scenarios, where the priority must always remain on the safety of the flight and its occupants.
