Having regard to the opinion of the Committee of the Regions,

Acting in accordance with the procedure laid down in Article
251 of the Treaty,

Whereas:

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

(2) Council Directive 94/56/EC of 21 November 1994 estab-
lishing the fundamental principles governing the investi-
gation of civil aviation accidents and incidents aims at
preventing future accidents by facilitating the expeditious
holding of investigations.

(3) Experience has shown that 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
actions.

(5) When these occurrences involve 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

to the people who may learn from it and take or initiate

(11) The sensitive nature of safety information is such that the
only way to ensure the gathering of such information is
by ensuring its confidentiality, the protection of its source
and the confidence of

the proposed action,

(17) In accordance with the principles of subsidiarity and
proportionality as set out in Article 5 of the Treaty, the
improvement of air
objective of
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 by the Community. This
Directive confines itself
to the minimum required in

what is necessary for that purpose.

(iv) Injury

Occurrences, which have or could have led to significant injury to passengers or crew but which are not
considered reportable as an accident.

B. AIRCRAFT TECHNICAL

(viii) Structural

Aircraft structural failures not classified as an accident.

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

1. Damage to a Principal Structural Element that has not been qualified as damage tolerant (life limited
element). Principal Structural Elements are those which contribute significantly to carrying flight,
ground, and pressurisation loads, and whose failure could result in a catastrophic failure of the aircraft

2. Typical examples of such elements are listed for large aeroplanes in AC/ACJ 25.571(a) (cid:145)damage tolerance

and fatigue evaluation of structure(cid:146), and in the equivalent ACJ material for rotorcraft

3. Defect or damage exceeding admissible damages to a Principal Structural Element that has been qualified as

damage tolerant, found during scheduled inspections.

4. Damage to or defect exceeding allowed tolerances of a structural element which failure could reduce the
structural stiffness to such an extent that the required flutter, divergence or control reversal margins are no
longer achieved.

5. 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.

6. Damage to or defect of a structural element, which could jeopardise proper operation of systems.

7. Loss of any part of the aircraft structure in flight

(ix) Systems

The following generic 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: e.g.

1. uncommented actions

2.

incorrect and or incomplete response, including limitation of movement or stiffness

3. Runaway

4. Mechanical disconnection or failure

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 flight and relevant to the operation of that

system.

(n) Occurrences of 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.
