Determine whether the occurrence is reportable

If you wish to report—in complete confidence—an act or condition in the Canadian transportation system that is potentially unsafe but is not a reportable occurrence as defined below, use SECURITAS.

Definition of a reportable occurrence
  1. in the case of an accident
    1. a person is killed or sustains a serious injury as a result of
      1. being on board the aircraft,
      2. coming into direct contact with any part of the aircraft, including parts that have become detached from the aircraft, or
      3. being directly exposed to jet blast, rotor down wash or propeller wash,
    2. the aircraft sustains structural failure or damage that adversely affects the aircraft's structural strength, performance or flight characteristics and would normally require major repair or replacement of any affected component, except for
      1. engine failure or damage, when the damage is limited to the engine, its cowlings or accessories, or
      2. damage limited to propellers, wing tips, antennae, tires, brakes, fairings or small dents or puncture holes in the aircraft's skin, or
    3. the aircraft is missing or inaccessible; and
  2. in the case of an incident involving an aircraft having a maximum certificated take-off weight greater than 2 250 kg, or of an aircraft being operated under an air operator certificate issued under Part VII of the Canadian Aviation Regulations
    1. an engine fails or is shut down as a precautionary measure,
    2. a power train transmission gearbox malfunction occurs,
    3. smoke is detected or a fire occurs on board,
    4. difficulties in controlling the aircraft are encountered owing to any aircraft system malfunction, weather phenomena, wake turbulence, uncontrolled vibrations or operations outside the flight envelope,
    5. the aircraft fails to remain within the intended landing or take-off area, lands with all or part of the landing gear retracted or drags a wing tip, an engine pod or any other part of the aircraft,
    6. a crew member whose duties are directly related to the safe operation of the aircraft is unable to perform their duties as a result of a physical incapacitation which poses a threat to the safety of persons, property or the environment,
    7. depressurization of the aircraft occurs that requires an emergency descent,
    8. a fuel shortage occurs that requires a diversion or requires approach and landing priority at the destination of the aircraft,
    9. the aircraft is refuelled with the incorrect type of fuel or contaminated fuel,
    10. a collision, a risk of collision or a loss of separation occurs,
    11. a crew member declares an emergency or indicates an emergency that requires priority handling by air traffic services or the standing by of emergency response services,

Guidelines on reporting an occurrence involving a remotely piloted aircraft system (RPAS)

A drone is considered an aircraft within the meaning of the Canadian Transportation Accident Investigation and Safety Board Act. All aviation occurrences mentioned in subsection 2(1) of the Transportation Safety Board Regulations involving a drone, regardless of its weight, must be reported to the TSB. However, the TSB has the discretion to decide which transportation occurrences it will investigate. In cases involving drones, the TSB will investigate accidents and incidents in which:

  1. a remotely piloted aircraft (RPA) weighing more than 25 kg (55 pounds) is involved in a reportable accident that meets the definition of a reportable occurrence above; or
  2. a person is killed or sustains a serious injury as a result of coming into direct contact with any part of a small RPA (an aircraft with a maximum take-off weight of at least 250 g [0.55 pounds] but not more than 25 kg [55 pounds]), including parts that have become detached; or
  3. a collision occurs between an RPA of any size or weight and a manned aircraft.

Who needs to report
