In accordance with Art. 3.1 of the 10th edition, applicable from 18 November 2010, of Annex 13 of the Convention on International Civil Aviation (ICAO) of 7 December 1944 and Article 24 of the Federal Air Navigation Act, the sole purpose of the investigation of an aircraft acci- dent or serious incident is to prevent accidents or serious incidents.

It is therefore not the purpose of this report to determine blame or clarify ques- tions of liability. If this report is used for purposes other than accident prevention, this may give rise to erro- neous interpretations.
