AIDS Reporting System Business Rules



  1. The data provided by ASIAS has been collected by people not directly associated with ASIAS. ASIAS does not certify the accuracy of the data.

  2. The data are maintained by Flight Standards Service, Regulatory Support Division, Aviation Data System Branch, AFS-620.

  3. The ASIAS database for AIDS contains incidents only; ASIAS uses the National Transportation Safety Board (NTSB) accident and incident database as the primary source for accident information.

  4. An Aircraft Accident is defined as “an occurrence associated with the operations of an aircraft which takes place between the time any person boards the aircraft with the intention of flight and until such time as all such persons have disembarked, and in which any person suffers death or serious injury, or in which the aircraft receives substantial damage.”

  5. Substantial Damage includes damage or failure which adversely affects the structural strength, performance, or flight characteristics of the aircraft, and which would normally require major repair or replacement of the affected component. Engine failure or damage limited to an engine if only one engine fails or is damaged, bent fairings or cowling, dented skin, small punctured holes in the skin or fabric, ground damage to rotor or propeller blades, and damage to landing gear, wheels, tires, flaps, engine accessories, brakes, or wing tips are not considered substantial damage.

  6. An Aircraft Incident is an occurrence, other than an accident associated with the operation of aircraft, which affects or could affect the safety of operations.

  7. The AIDS database contains reports of incidents from 1978 to the present. The database is updated monthly.

  8. Prior to 1995, the narratives for AIDS reports were limited to 115 characters; reports since 1995 contain the complete narrative prepared by the investigating inspector.

  9. If more than one aircraft is involved in an incident, two separate reports appear in the database.

  10. The AIDS database contains records of serious or fatal injuries that result from voluntary parachute jumps.

  11. In addition to AIDS specific codes for the primary or secondary cause, the AIDS database uses an industry coding system to identify an aircraft system or component. Originally AIDS used the Air Transport Association (ATA) Specification 100 codes. In 1996, AFS-620 adopted the Joint Aircraft/System Component (JASC) codes. ASIAS maintains a lookup table for the JASC codes and meanings.

  12. Please note that the causal information codes used in the FAA Accident and Incident Data System (AIDS) differs from the causal information codes used in the NTSB Aviation Accident and Incident Data System (NTSB).
