Transportation Safety Board of Canada

Aviation Safety Investigation: The purpose of an aviation safety investigation into an aircraft accident of incident is to prevent a recurrence; It is not to determine or apportion blame or liability.

Aviation Occurence:

  • Any accident of incident associated with the operation of an aircraft, and
  • any situation or condition that the Board has reasonable grounds to believe could, if left unattended, induce an accident or incident described in paragraph(a).
    • Collision – Impact, other than an impact associated with normal operating circumstances, between aircraft or between an aircraft and another object or terrain.
    • Dangerous goods – see transportation dangerous goods
    • Operation – activities for which an aircraft is used from the time any person boards the aircraft with the intention of flight until they disembark.
    • Risk of collision – situation in which an aircraft comes so close to being involved in a collision that a threat to the safety of any person, property or the environment exist

Serious injury:

  • a fracture of any bone , except simple fractures of fingers, toes or the nose;
  • lacerations that cause severe hemorrhage or nerve, muscle or tendon damage;
  • an injury to an internal organ;
  • second or third degree burns, or any burns affecting more than 5% of the body surface;
  • a verified exposure to infectious substances or injurious radiation; or
  • an injury that is likely to require hospitalization.

Accidents

  • (1) a person is killed or sustains a serious injury as a result of:
  • (a) being on board the aircraft,
  • (b) coming into direct contact with any part of the aircraft,
  • including parts that have become detached from the
  • aircraft, or
  • (c) being directly exposed to jet blast, rotor down wash or
  • propeller wash, 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:
  • (d) engine failure or damage, when the damage is limited
  • to the engine, its cowlings or accessories, or
  • (e) damage limited to propellers, wing tips, antennae,

  • 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,
  • (12) a slung load is released unintentionally or as a
  • precautionary or emergency measure from the aircraft,

Other occurances

Any other incident indicative of a deficiency or discrepancy
