Aviation Safety Council （hereafter referred as ASC） was established in
accordance with the Article 84 of the Republic of China Civil Aviation Law. ASC’s authority shall be independent of any other government authorities. ASC classifies aviation occurrence categories conducts investigations, and identifies the causes with the purpose of preventing the similar accidents and incidents from happening again instead of administering discipline and placing blame.
Aviation occurrence Investigation Standard Operation Procedure （hereafter
referred as the Procedure） was put into effective on April 1, 1999, as the guideline of ASC’s investigation operations. The Procedure will be revised when necessary to reflect the change of regulations relevant to civil aviation, the practical needs of investigation, and the comments from users.
