About ASC
Why would the Aviation Safety Council be set up to investigate aviation occurrences?

Between 1981 and 1998, there was no independent accident investigation organization.  During that period, the civil aviation accident rate of our country remained high.  In 1998, two fatal accidents happened in succession. The Executive Yuan thus decided to establish a permanent organization to conduct the aviation occurrence investigation independently, so as to prevent similar occurrences from reoccurrence. Then, the "Aircraft Aviation Safety Council, ASC" was set up on May 25, 1998.

On May 20, 2012, the Aviation Safety Council restructured and officially became an independent agency.

        The ASC is responsible for the investigation of aviation occurrences of civil aircraft, public aircraft, and ultra-light vehicle. The investigation operation includes aviation occurrence identification, probable causes identification, safety recommendations submission, and investigation report preparation.


How does the Aviation Safety Council (ASC) independently conduct the investigation?

The purpose of aviation occurrence investigation carried out by the ASC is to prevent the similar occurrences from reoccurrence, different from the civil aviation authority designed to carry out supervising jobs, such as enacting regulations, punishing the violators, supervising the airlines operations, etc. Looking around the accident investigation organizations internationally, such as the United States, Canada, France, Germany, Britain, Norway, the Netherlands, Switzerland, Denmark, Finland, Sweden, Australia, New Zealand, Japan South Korea, Indonesia, Russia and the Republic of China, all of these countries own independent investigation agencies. The International Transportation Safety Association (ITSA), a professional organization composed of transportation accident investigation agencies of many nations, particularly emphasizes the importance of independence of the investigating agencies. Independence is also a necessary condition for the agencies to join the association (ASC is a member of ITSA). The association asserts that the real causes of occurrences can only be found through independent investigation free of interference.

After the release of the investigation report, the ASC issues safety recommendations based on the probable causes of the occurrence to the civil aviation authority or relevant agencies. The safety recommendations for the improvement of aviation safety shall be supervised as watch items by the Executive Yuan and tracked by the ASC until the improvement measures are completed according to implementation plans.

If the occurrence investigation agency is under the Ministry of Transportation and Communications or the regulatory system, the agency may not be able to independently exercise investigations due to the administration sabjection relations, thereby affect to find out the causes of the occurrence. This is definitely not the best way to improve the aviation safety.


Does the Aviation Safety Council (ASC) have an administration subjection relations with the Ministry of Transportation and Communications or the Civil Aeronautics Administration?

      The Ministry of Transportation and Communications, the Civil Aeronautics Administration and the Aviation Safety Council are closely related to civil aviation, but each has its own functions.

      The Ministry of Transportation and Communications is in charge of the policy of transportation (highways, marine, and aviation).

      The Civil Aeronautics Administration (CAA) is affiliated to Ministry of Transportation and Communications, responsible for expanding the air rights and air routes, airport planning and construction, aviation safety supervision, aviation industry guidance, air traffic control services, etc., thus the CAA is a regulatory agency for civil aviation. The CAA also has investigating tasks, but are those not related to aviation occurrences or the ground incidents when the aircraft not in operation.

      The Aviation Safety Council is affiliated to Executive Yuan, responsible for the aviation occurrence investigation of civil aircraft, official aircraft and ultra-light vehicle. The objective of the ASC‘s investigation of aviation occurrence is to prevent recurrence of similar occurrences. It is not the purpose of such investigation to apportion blame or liability.


What do the board members of the Aviation Safety Council (ASC) do?

The board meeting is held monthly and the chairperson, vice chairperson and other board members will all attend. The ASC’s board meeting shall resolve the followings:

  1. Review and approve the aviation occurrence investigation report.
  2. Review and approve the re-investigation of an aviation occurrence.
  3. Review and approve laws and regulations governing aviation occurrence investigation.
  4. Review and approve the operational mechanisms of coordination and communication between the ASC and other related organizations.
  5. Review and approve ASC’s annual budget and final accounts.
  6. Review and approve a board member’s draft proposal.
  7. Other decisions defined by law to be made by the Board Meeting.


Does the Aviation Safety Council have contact with other international aviation occurrence investigation agencies or organizations?

       The Council has maintained very close contact with foreign investigating agencies, cooperation agreements been singed with following countries:

  • Australian Transport Safety Bureau(ATSB)
  • Transportation Safety Board of Canada(TSB)
  • French Accident Investigation Agency(BEA)
  • The UK Air Accidents Investigation Branch(AAIB)
  • Japan Transportation Safety Board(JTSB)
  • Korean Aviation and Railway Accident Investigation Board(KARAIB)
  • The US National Transportation Safety Board(NTSB)

        The Council has also actively joined international organizations of aviation safety and accident investigation, delegates are participating to the annual meeting of the organizations every year, exchanging technologies and experiences professional investigators from across the world, including International Society of Air Safety Investigators (ISASI), International Flight Safety Foundation (FSF), International Transportation Safety Association (ITSA), Accident Investigators Recorder Meeting (AIR Meeting) and the International Confidential Aviation Safety Reporting System (ICASS).


What laws and regulations are the bases for the Aviation Safety Council (ASC) to carry out the aviation occurrence investigation?

The laws and regulations that are the bases for the Aviation Safety Council to carry out the aviation occurrence investigation include:

  1. Aviation Occurrence Investigation Act

    The Aviation Occurrence Investigation Act was promulgated on June 2, 2004 and amended on June 18, 2014, containing five chapters and 38 sections.

  2. The Regulation Governing the Handling of Investigation Procedures for Aviation Occurrence for Civil and Public Aircraft Occurrence" and "The Regulation Governing the Handling of Investigation Procedures for Ultra-light Vehicle Occurrence", were promulgated on December 21, 2004 and amended on November 20, 2014.

  3. International Civil Aviation Organization Annex 13 (ICAO Annex 13)

    Though our country is not a member state of the ICAO, “The Aviation Occurrence Investigation Act”, and "The Regulation Governing the Handling of Investigation Procedures for Civil and Public Aircraft Occurrence" and the Standard Operation Procedures (SOP) for aviation occurrence investigation were enacted referring to the standards and recommended practices of ICAO Annex 13.
