Aviation Safety Reporting Program
This advisory circular (AC) describes the Federal Aviation Administration (FAA) Aviation Safety Reporting Program (ASRP) which utilizes the National Aeronautics and Space Administration (NASA) as a third party to receive and process Aviation Safety Reports. This cooperative safety reporting program invites pilots, controllers, Flight Attendants (F/A), maintenance personnel, dispatchers, and other users of the National Airspace System (NAS), or any other person, to report to NASA actual or potential discrepancies and deficiencies involving the safety of aviation operations. The operations covered by the program include departure, en route, approach, and landing operations and procedures; air traffic control (ATC) procedures and equipment; crew and ATC communications; aircraft cabin operations; aircraft movement on the airport; near midair collisions (NMAC); aircraft maintenance and recordkeeping; and airport conditions or services. The effectiveness of this program in improving safety depends on the free, unrestricted flow of information from the users of the NAS. Based on information obtained from this program, the FAA will take corrective action as necessary to remedy defects or deficiencies in the NAS. The reports may also provide data for improving the current system and planning for a future system.
