Air Navigation Services, Facilities and Ground Services

Air Navigation Services (ANS)

• Near collision incidents (encompassing specific situations where one aeroplane and another aeroplane/ground/vehicle/person or object are perceived to be too close to each other):
   - Separation minima infringement;
   - Inadequate separation;
   - Near-controlled flight into terrain (near CFIT);
   - Runway incursion where avoiding action was necessary.
• Potential for collision or near collision (encompassing specific situations having the potential to be an accident or a near collision, if another aeroplane is in the vicinity):
   - Runway incursion where no avoiding action is necessary;
   - Runway excursion;
   - Aeroplane deviation from ATC clearance;
   - Aeroplane deviation from applicable air traffic management (ATM) regulation.
• ATM-specific occurrences (encompassing those situations where the ability to provide safe ATM services is affected, including situations where, by chance, the safe operation of aeroplane has not been jeopardised). This shall include the following occurrences:
   - Inability to provide air traffic services;
   - Inability to provide airspace management services;
   - Inability to provide air traffic flow management services.

The following list gives examples of reportable ATM occurrences resulting from the application of the general criteria listed in paragraph above:
• Provision of significantly incorrect, inadequate or misleading information from any ground sources, e.g. air traffic control (ATC), automatic terminal information service (ATIS), meteorological services, navigation databases, maps, charts, manuals, etc;
• Provision of less than prescribed terrain clearance;
• Provision of incorrect pressure reference data (i.e. altimeter setting);
• Incorrect transmission, receipt or interpretation of significant messages when this results in a hazardous situation;
• Unauthorised penetration of airspace;
• Failure of ANS ground or satellite facilities;
• Major ATC/ATM failure or significant deterioration of aerodrome infrastructure;
• Aerodrome movement areas obstructed by aeroplane, vehicles, animals or foreign objects, resulting in a hazardous or potentially hazardous situation;
• Errors or inadequacies in marking of obstructions or hazards on aerodrome movement areas resulting in a hazardous situation;
• Failure, significant malfunction or unavailability of aerodrome lighting.

Aerodrome and Aerodrome Facilities

• Significant spillage during fuelling operations.
• Loading of incorrect fuel quantities likely to have a significant effect on aeroplane endurance, performance, balance or structural strength.

Handling of Passengers, Baggage and Cargo

• Significant contamination of aeroplane structure, systems and equipment arising from the carriage of baggage or cargo.
• Incorrect loading of passengers, baggage or cargo, likely to have a significant effect on aeroplane mass and/or balance.
• Incorrect storage of baggage or cargo (including hand baggage) likely in any way to endanger the aeroplane, its equipment or occupants or to impede emergency evacuation.
• Inadequate storage of cargo containers or other substantial items of cargo.
• Carriage or attempted carriage of dangerous goods in contravention of applicable regulations, including incorrect labelling and packaging of dangerous goods.

Aeroplane Ground Handling and Servicing

• Failure, malfunction or defect of ground equipment used for the testing or checking of aeroplane systems and equipment when the required routine inspection and test procedures did not clearly identify the problem, where this results in a hazardous situation.
• Non-compliance or significant errors in compliance with required servicing procedures.
• Loading of contaminated or incorrect type of fuel or other essential fluids (including oxygen and potable water).
