Aviation Safety Reporting System

The Aviation Safety Reporting System, or ASRS, is the US Federal Aviation Administration's (FAA) voluntary confidential reporting system that allows pilots, air traffic controllers, cabin crew, dispatchers, maintenance technicians, ground operations, and UAS operators and drone flyers to confidentially report near misses or close call events in the interest of improving aviation safety. The ASRS collects, analyzes, and responds to voluntarily submitted aviation safety incident reports in order to reduce the likelihood of aviation accidents.
