Data extracted August 15, 2017
Reportable accidents and incidents are reported in accordance with the TSB's regulations for mandatory reporting of occurrences.
Breakdowns may not add up to totals. For example, in the total "Number of accidents by aircraft type", when an occurrence involves an airplane and a helicopter, the occurrence is counted in each category, but only once in the total.
*Only "Number of aircraft involved in accidents" are aircraft counts, all other data are accident counts.
a. The commercial service type is not available for foreign-registered aircraft.
b. Other: contains, but is not limited to, organizations that rent aircraft (i.e., flying schools, flying clubs, etc.).
c. Includes balloons, gyroplanes, gliders, dirigibles, hang gliders, unmanned aerial vehicles (UAV) and similar aircraft types.
New TSB regulations came into effect on July 1, 2014, changing some reporting requirements.
**Under new reporting requirements aviation incidents include: a) aircraft having a maximum certificated take-off weight greater than 2 250 kg (formerly 5700 kg); b) aircraft being operated under an air operator certificate issued under CARS Part VII.
