The FAA's immunity policy encourages submission of all safety incidents and observations, especially information that could prevent a major accident, even if a violation occurs. If enforcement action is taken by the FAA against an accidental rule violation that did not result in an accident, a reporter can present their ASRS form as proof that the incident was reported to NASA in the interest of aviation safety. The FAA views the report as evidence of a "constructive safety attitude" and will not impose a penalty.[2] However, this immunity can only be exercised once every five years, though an unlimited number of reports can be filed.
