ADR.OR.D.005(b)(4) AMC1 Management system
SAFETY RISK ASSESSMENT AND MITIGATION
(a) A formal safety (risk) assessment and mitigation process should be developed and
maintained that ensures analysis (in terms of probability and severity of occurrence),
assessment (in terms of tolerability), and control (in terms of mitigation) of risks.
(b) The levels of management who have the authority to make decisions regarding the
tolerability of safety risks, in accordance with (a) above, should be specified in the
aerodrome manual.
ADR.OR.D.005(b)(4) GM1 Management system
SAFETY RISK ASSESSMENT AND MITIGATION
Safety (risk) assessment is the analysis of the safety risks of the consequences of the hazards that
have been determined. Safety risk analysis breaks down the risks into two components - the
probability of occurrence of a damaging event or condition, and the severity of the event or condition,
should it occur. Safety risk decision making and acceptance should be specified through a risk
tolerability matrix. The definition and final construction of the matrix should be left to the operator to
design, be documented in the aerodrome manual, and be subject to an approval by the CAA.
ADR.OR.D.005(b)(5) AMC1 Management system
SAFETY PERFORMANCE MONITORING AND MEASUREMENT
(a) Safety performance monitoring and measurement should be the process by which the
safety performance of the aerodrome operator is verified in comparison to the safety
policy and objectives, identified safety risks and the mitigation measures.
(b) This process should include the setting of safety performance indicators and safety
performance targets, and measuring the aerodrome operator’s safety performance
against them.
ADR.OR.D.005(b)(5) GM1 Management system
SAFETY PERFORMANCE MONITORING AND MEASUREMENT
(a) The performance monitoring and measurement process should include:
(1) safety reporting, addressing also the status of compliance with the applicable
requirements;
(2) safety studies which are rather large analyses encompassing broad safety
concerns;
(3) safety reviews including trends reviews which are conducted during introduction
and deployment of new technologies, change or implementation of procedures, or in
situations of structural change in operations, or to explore increase in incidents or
safety reports;
(4) safety audits which focus in the integrity of the aerodrome operator’s management
system, and periodically assess the status of safety risk controls;
(5) safety surveys, which examine particular elements or procedures of a specific
operation, such as problem areas or bottlenecks in daily operations, perceptions
and opinions of operational personnel, and areas of dissent or confusion; and
(6) internal safety investigations whose scope should extend the scope of occurrences
required to be reported to the CAA;
(b) The following generic aspects/areas could be considered:
(1) accountability for management of the operational activities and its ultimate
accomplishment;
(2) authority to direct, control, or change the procedures, as well as to make key
decisions such as safety risk acceptance decisions;
(3) procedures for operational activities;
(4) controls, including hardware, software, special procedures or procedural steps, and
supervisory practices designed to keep operational activities on track;
(5) interfaces, including lines of authority between departments, lines of communication
between employees, consistency of procedures, and clear delineation of
responsibility between organisations, work units, and employees; and
(6) process measures to provide feedback to responsible parties that required actions
are taking place, required outputs are being produced, and expected outcomes are
being achieved.
ADR.OR.D.005(b)(6) AMC1 Management system
THE MANAGEMENT OF CHANGE
The aerodrome operator should manage safety risks related to a change. The management of
change should be a documented process to identify external and internal change that may have an
adverse effect on safety.
It should make use of the aerodrome operator’s existing hazard identification, safety (risk)
assessment, and mitigation processes.
ADR.OR.D.005(b)(6) GM1 Management system
THE MANAGEMENT OF CHANGE
(a) Change can introduce new hazards, impact the appropriateness and/or effectiveness of
existing safety risk mitigation strategies. Changes may be external to the organisation, or
internal.
(b) A formal process for the management of change should take into account the following
considerations:
