Dear visitor,
Dear network colleagues,

Welcome to the ENCASIA website, designed to provide you with information on the European Network of Civil Aviation Safety Investigation Authorities (ENCASIA) and our role within the European framework. This site contains information about our members and other organizations involved in aviation safety. It also provides links to websites you might find useful. Our main focus is cooperation to further improve aviation safety. I hope that its content will provide you with the information you need. 

With the financial implementation of the annual work programmes since 2011 and the ENCASIA ASBL legal basis, the Network has built the platform for successful and solid work in the next years. 

It is now important that the adopted resolutions continue to be implemented. This has required a substantial commitment from everyone involved and has tied up resources, but this cooperative effort has been crucial. I have been very thankful to everyone for providing resources and for their active involvement in the work programme.

The same has been true for the participation in the ENCASIA working groups. They all help to implement the objectives that Regulation (EU) No 996/2010 has given to the SIAs with the request to increase the efficiency of the civil aviation safety investigation system in Europe and subsequently improve flight safety.

Since the former Directive 94/56/EC had been implemented, the number of investigations of serious incidents in civil aviation has begun to increase. In many of the European SIAs, the invested manpower to pro-actively investigate serious incidents with transport aircraft has represented a substantial proportion of the resources which are available in this area.

I would like to underline that inputs from the different safety partners are duly taken into account by the Network as well as the various viewpoints that have been expressed by participating colleagues. Since the establishment of ENCASIA, we have had a 50 % increase in number of members. New colleagues have been welcomed to ENCASIA's construction that aims to generate real added value for efficient safety investigations in Europe.

Once again, welcome to our ENCASIA website!

Ulf Kramer, ENCASIA Chairman January 2015

The Network constitutes an independent grouping of the air safety investigation authorities of the EU Member States. Its establishment is envisaged by the recently adopted Regulation (EU) 996/2010  on the investigation and prevention of accidents and incidents in civil aviation, which entered into force on 2 December 2010.

The mission of the Network is to further improve the quality of air safety investigations and to strengthen the independence of the national investigating authorities. It is responsible for issues such as:

  • development of training activities,
  • promoting safety investigation best practices,
  • developing a mechanism for sharing investigating resources,
  • advising EU institutions on air accident investigation and prevention matters.

The detailed activities of the Network are defined in its annual work programme.

Legal framework

The Convention on International Civil Aviation, also known as the Chicago Convention (signed on 7 December 1944) established the International Civil Aviation Organization (ICAO), a specialised agency of the United Nations charged with coordinating and regulating international air travel. This is to stimulate future development of international civil aviation, which can help create and preserve friendship and understanding among nations and to avoid its abuse becoming a threat to general security.

Because investigation of incidents and accidents can prevent future occurrences and improve air transport safety, Article 26 of this convention imposes an obligation on the State whereby in the case of an aircraft accident, the State must institute an inquiry into certain circumstances and, as far as its laws permit, conduct the inquiry in accordance with ICAO standards and procedures. These standards and Recommended Practices for Aircraft Accident Inquiries were first adopted on 11 April 1951 and were designated as Annex 13 to the Convention.

Having recognised the importance of accident investigation in civil aviation, in 1980 the European Union adopted Directive 80/1266/EEC  on cooperation and mutual assistance between the Member States in the field of air accident investigation. This was the first ever piece of aviation safety legislation adopted in the Community. The Directive of 1980 was subsequently replaced by Directive 94/56/EC . By transposing a number of fundamental principles contained in Annex 13 into the Community legislation, Directive 94/56/EC significantly contributed to the harmonisation of civil aviation accident investigation in the EU.

In 2010, the European Commission conducted a comprehensive review of EU legislation on civil aviation accident and incident investigations, with a view to updating and modernising it. Today, investigation of air accidents requires more diversified expertise and resources than a decade ago. The EU institutional and legal framework also changed substantially, notably for the European Aviation Safety Agency (EASA), being responsible for certification of aircraft in the EU. This review resulted in the adoption of Regulation (EU) No 996/2010 , which currently provides the legal framework for conducting civil aviation accident and incident investigations in the EU.

EU cooperation

Following the entry into force of Regulation (EU) No 996/2010, civil aviation safety investigation authorities of EU Member States gathered on 19 January 2011 in Brussels to establish the "European Network of Civil Aviation Safety Investigation Authorities" (ENCASIA).

The Network is chaired by Mr Ulf Kramer, Head of the air safety investigation authority of Germany. Mr Keith Conradi, Head of the air safety investigation authority of the United Kingdom, acts as Deputy Chairman.

ENCASIA constitutes an independent grouping of the 28 civil aviation safety investigation authorities of the EU Member States.

It is composed of the heads of the safety investigation authorities in each of the Member States and/or, in the case of a multimodal authority, the head of its aviation branch, or their representatives.
