Directive 2003/42/EC of the European Parliament and of the Council

of 13 June 2003

on occurrence reporting in civil aviation

THE EUROPEAN PARLIAMENT AND THE COUNCIL OF THE EUROPEAN UNION,

Having regard to the Treaty establishing the European Community, and in particular Article 80(2) thereof,

Having regard to the proposal from the Commission(1),

Having regard to the opinion of the European Economic and Social Committee(2),

Following consultation of the Committee of the Regions,

Acting in accordance with the procedure laid down in Article 251 of the Treaty(3), in the light of the joint text approved by the Conciliation Committee on 9 April 2003,

Whereas:

(1) The rate of accidents in civil aviation has remained fairly constant in the last decade; nevertheless there is concern that the forecasted traffic increase could lead to an increase in the number of accidents in the near future.

(2) Council Directive 94/56/EC of 21 November 1994 establishing the fundamental principles governing the investigation of civil aviation accidents and incidents(4), aims at preventing accidents by facilitating the expeditious holding of investigations.

(3) Experience has shown that often before an accident occurs, a number of incidents and numerous other deficiencies have shown the existence of safety hazards.

(4) The improvement of the safety of civil aviation requires a better knowledge of these occurrences to facilitate analysis and trend monitoring in order to initiate corrective action.

(5) When an occurrence involves aircraft registered in a Member State or operated by an undertaking established in a Member State, this occurrence should be reported even when it happened outside the territory of the Community.

(6) Each Member State should set up mandatory reporting systems.

(7) Various categories of personnel working in civil aviation observe occurrences of interest for the prevention of accidents and should therefore report them.

(8) The efficiency of detection of potential hazard would be greatly enhanced by the exchange of information on such occurrences.

(9) Supporting software for the exchange of information between different systems is necessary.

(10) Safety information should be available to entities entrusted with regulating civil aviation safety or investigating accidents and incidents within the Community and, as appropriate, to the people who may learn from them and take or initiate the necessary action to improve safety.

(11) The sensitive nature of safety information is such that the way to ensure its collection is by guaranteeing its confidentiality, the protection of its source and the confidence of the personnel working in civil aviation.

(12) The public should be provided with general information on the level of aviation safety.

(13) Appropriate measures should be put in place to enable the setting up of confidential reporting schemes.

(14) The measures necessary for the implementation of this Directive should be adopted in accordance with Council Decision 1999/468/EC of 28 June 1999 laying down the procedures for the exercise of implementing powers conferred on the Commission(5).

(15) Consistency should be ensured with the technical reporting requirements developed by national experts in Eurocontrol and the Joint Aviation Authorities Organisation. The list of reportable occurrences should take into account the work of these two European organisations. Developments in the framework of the International Civil Aviation Organisation should also be taken into account.

(16) Since the objective of the proposed action, namely the improvement of air safety, cannot be sufficiently achieved by the Member States because reporting systems operated by Member States in isolation are less efficient than a coordinated network with exchange of information enabling an earlier identification of possible safety problems, and can, therefore, be better achieved at Community level, the Community may adopt measures in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty. In accordance with the principle of proportionality as set out in that Article, this Directive does not go beyond what is necessary in order to achieve those objectives,

HAVE ADOPTED THIS DIRECTIVE:

Article 1

Objective

The objective of this Directive is to contribute to the improvement of air safety by ensuring that relevant information on safety is reported, collected, stored, protected and disseminated.

The sole objective of occurrence reporting is the prevention of accidents and incidents and not to attribute blame or liability.

Article 2

Definitions

For the purpose of this Directive:

1. "occurrence" means an operational interruption, defect, fault or other irregular circumstance that has or may have influenced flight safety and that has not resulted in an accident or serious incident, hereinafter referred to as "accident or serious incident", as defined in Article 3(a) and (k) of Directive 94/56/EC;

2. "disidentification" means removing from reports submitted all personal details pertaining to the reporter and technical details which might lead to the identity of the reporter, or of third parties, being inferred from the information.

Article 3

Scope

1. This Directive shall apply to occurrences which endanger or which, if not corrected, would endanger an aircraft, its occupants or any other person. A list of examples of these occurrences appears in Annexes I and II.

2. The Commission may, in accordance with the procedure laid down in Article 10(2), decide to amend the Annexes in order to expand upon, or change, the examples.

3. The application of this Directive to the airport of Gibraltar is understood to be without prejudice to the respective legal positions of the Kingdom of Spain and the United Kingdom with regard to the dispute over sovereignty over the territory in which the airport is situated.

4. Application of this Directive to the airport of Gibraltar shall be suspended until the arrangements in the Joint Declaration made by the Foreign Ministers of the Kingdom of Spain and the United Kingdom on 2 December 1987 have come into operation. The Governments of Spain and the United Kingdom will inform the Council of such date of entry into operation.

Article 4

Mandatory reporting

ANNEX I

List of aircraft operations, maintenance, repair, and manufacture-related occurrences to be reported

Note 1: Although this Annex lists the majority of reportable occurrences, it cannot be completely comprehensive. Any other occurrences, which are judged by those involved to meet the criteria, should also be reported.

Note 2: This Annex does not include accidents. In addition to other requirements covering the notification of accidents, they should also be recorded in the database mentioned in Article 5(2).

Note 3: This Annex contains examples of reporting requirements covering aircraft operations, maintenance, repair and manufacture.

Note 4: Occurrences to be reported are those where the safety of operation was or could have been endangered or which could have led to an unsafe condition. If in the view of the reporter an occurrence did not endanger the safety of the operation but if repeated in different but likely circumstances would create a hazard, then a report should be made. What is judged to be reportable on one class of product, part or appliance may not be so on another and the absence or presence of a single factor, human or technical, can transform an occurrence into an accident or serious incident.

Note 5: Specific operational approvals, e.g. RVSM, ETOPS, RNAV, or a design or maintenance programme, may have specific reporting requirements for failures or malfunctions associated with that approval or programme.

B. AIRCRAFT TECHNICAL

(i) Structural

Not all structural failures need to be reported. Engineering judgment is required to decide whether a failure is serious enough to be reported. The following examples can be taken into consideration:

(a) damage to a principal structural element (PSE) that has not been designated as damage-tolerant (life-limited element). PSEs are those which contribute significantly to carrying flight, ground, and pressurisation loads, and the failure of which could result in a catastrophic failure of the aircraft;

(b) defect or damage exceeding admissible damages to a PSE that has been designated as damage-tolerant;

(c) damage to or defect exceeding allowed tolerances of a structural element, the failure of which could reduce the structural stiffness to such an extent that the required flutter, divergence or control reversal margins are no longer achieved;

(d) damage to or defect of a structural element, which could result in the liberation of items of mass that may injure occupants of the aircraft;

(e) damage to or defect of a structural element, which could jeopardise proper operation of systems. See (ii) below;

(f) loss of any part of the aircraft structure in flight.

(ii) Systems

The following general criteria applicable to all systems are proposed:

(a) loss, significant malfunction or defect of any system, subsystem or set of equipment when standard operating procedures, drills etc. could not be satisfactorily accomplished;

(b) inability of the crew to control the system, for example:

1. uncommanded actions,

2. incorrect and/or incomplete response, including limitation of movement or stiffness,

3. runaway,

4. mechanical disconnection or failure;

(c) failure or malfunction of the exclusive function(s) of the system (one system could integrate several functions);

(d) interference within or between systems;

(e) failure or malfunction of the protection device or emergency system associated with the system;

(f) Loss of redundancy of the system.

(g) Any occurrence resulting from unforeseen behaviour of a system.

(h) For aircraft types with single main systems, subsystems or sets of equipment:

loss, significant malfunction or defect in any main system, subsystem or set of equipment.

(i) For aircraft types with multiple independent main systems, subsystems or sets of equipment:

the loss, significant malfunction or defect of more than one main system, subsystem or set of equipment.

(j) Operation of any primary warning system associated with aircraft systems or equipment unless the crew conclusively established that the indication was false, provided that the false warning did not result in difficulty or hazard arising from the crew response to the warning.

(k) Leakage of hydraulic fluids, fuel, oil or other fluids which resulted in a fire hazard or possible hazardous contamination of aircraft structure, systems or equipment, or risk to occupants.

(l) Malfunction or defect of any indication system when this results in the possibility of misleading indications to the crew.

(m) Any failure, malfunction or defect if it occurs at a critical phase of the flight and is relevant to the system operation.

(n) Significant shortfall of the actual performances compared to the approved performance which resulted in a hazardous situation (taking into account the accuracy of the performance-calculation method) including braking action, fuel consumption etc.

(o) Asymmetry of flight controls; e.g. flaps, slats, spoilers etc.

The Appendix to this Annex gives a list of examples of reportable occurrences resulting from the application of these general criteria to specific systems.

(iii) Propulsion (including engines, propellers and rotor systems) and auxiliary power units (APUs)

(a) Flameout, shutdown or malfunction of any engine.

(b) a secondary structure which consequently has or may have endangered the aircraft;

(c) the engine, propeller or rotorcraft rotor system.

(v) Any failure, malfunction or defect of any system or equipment, or damage or deterioration thereof found as a result of compliance with an airworthiness directive or other mandatory instruction issued by a regulatory authority, when:

(a) it is detected for the first time by the reporting organisation implementing compliance;

(b) on any subsequent compliance, it exceeds the permissible limits quoted in the instruction and/or published repair/rectification procedures are not available.
