Statistical Summary – Aviation Occurrences 2016
This document is a summary of selected 2016 aviation safety data.
The TSB gathers and uses this data during the course of its investigations to analyse safety deficiencies and identify risks in the Canadian transportation system.
The 2016 data were collected according to the reporting requirements described in the TSB Regulations in force during that calendar year.
The statistics presented here reflect the TSB database at 29 March 2017. Since the occurrence data are constantly being updated in the live database, the statistics may change slightly over time.
Also, as many occurrences are not formally investigated, information recorded on some occurrences may not have been verified.
A series of data tables associated with this annual summary is also available.
Overview of accidents and fatalities
In 2016, a total of 229 aviation accidents were reported to the TSB, down from the previous year's total of 251, down 14% from the 5-year average of 265 and down 19% from the 10-year average of 283. Of the total, 199 involved Canadian-registered aircraft (excluding ultra-lights)Footnote 1, a 12% decrease from the previous year's total of 227, a 14% decrease from the 5-year average of 230, and a 19% decrease from the 10-year average of 244.
The 2016 estimate of flying activity is 4,301,000 hoursFootnote 2, and the accident rate for Canadian-registered aircraft was 4.5 accidents per 100 000 flying hours, a decrease from the previous year's accident rate of 5.2. Analysis using linear regression indicates a statistically significant downward trend in accident rates (p < . 001)Footnote 3 over the 10-year period from 2007 to 2016 (Figure 1). Similarly, the 2016 accident rate of 3.3 accidents per 100 000 aircraft movements decreased from the 2015 rate of 3.7 accidents per 100 000 aircraft movements, and that rate has also trended significantly downward (p < .05) over the same 10-year period.

The 199 accidents involving Canadian-registered aircraft (Figure 2), included 166 accidents involving aeroplanesFootnote 4 (41 accidents involved commercially operated aeroplanes) and 27 accidents involving helicopters. The remaining six accidents involved 4 gliders, 1 gyroplane, and 1 rotary wing unmanned aerial system (UAS).
Of the 41 accidents involving 43 Canadian-registered commercially operated aeroplanes (1 airliner, 2 commuter aircraft, 16 air taxi, 7 aerial work, and 17 flight training) in 2016, 3 accidents resulted in a total of 5 fatalities. One fatal accident involved an air taxi, 1 involved aerial work, and 1 involved flight training.
A total of 125 accidents involved Canadian-registered private/other aeroplanes, 2% lower than the 5-year average of 128. In 2016, 18 such accidents resulted in fatalities, up from 13 in 2015, and up from the 5-year average of 13.

In 2016, 24 fatal accidents involved Canadian-registered aircraft other than ultra-lights (Figure 3), up slightly fromthe 2015 total of 23, but down from the 5-year average of 26 and the 10-year average of 28.
The number of fatalities (34), was lower than the 2015 total of 40, and lower than the 5-year average of 46 and the 10-year average of 51. The number of serious injuries (16) was lower than the 2015 total of 29, the 5-year average of 32, and the 10-year average of 36.

In 2016, crew fatalities accounted for 56% of aircraft fatalities, and passenger fatalities accounted for 44%.
In 2016, 27 accidents involved Canadian-registered helicopters, down from the 5-year average of 34. two of these accidents were fatal, resulting in a total of 3 fatalities. Over the past 10 years, the highest proportion of helicopter accidents occurred during air transport operations (37%), pleasure/travel (18%), and training (8%).
In 2016, 22 accidents in Canada involved Canadian-registered ultra-light aircraft, a 12% decrease from the 5-year average of 25. Four of these were fatal accidents resulting in 4 fatalities in total.
In 2016, 8 accidents involved foreign-registered aircraft in Canada, with 1 fatal accident resulting in a total of 7 fatalities.
Accidents by selected categories
Operation Type (Table 6): In 2016, aeroplane accidents occurred mainly on recreational flights (67%), training flights (12%), and air transport (9%). Helicopter accidents occurred mainly on recreational flights (33%) and air transport flights (26%).
Province (Table 8): British Columbia accounted for 22% of Canadian-registered aircraft accidents and incurred a 10% increase from its 5-year average, and Ontario accounted for 21% of Canadian registered aircraft accidents with a 27% decrease from its 5-year average. Alberta accounted for 18%, with a 42% increase from its 5-year average (Figure 4).

Accident Events and Phases
Accidents may be analyzed in more detail by examining the nature and distribution of selected events contributing to an occurrence. Tables 11 and 12 show counts of accidents involving selected event types within each phase of flight.
Although a single accident may involve more than one event within a phase, that accident is only counted once in the phase total. Therefore, the total of events within a phase will not sum to phase event totals. For example, in the "take-off" phase, if an occurrence involves both "loss of control " and "power loss" events, the occurrence is counted in each event category, but only once in the phase total. As well, approximately 23% of aeroplane accidents and 25% of helicopter accidents involve events in more than one phase of flight (not including "post-impact"), so the accidents shown in Figure 5 and Figure 6 sum to more than the total of accidents.
In 2016, the distribution was similar to that of 2015. The greatest numbers of aeroplane accidents were associated with landing (65%) and take-off (27%) phases of flight, followed by en route (11%) and approach (10%) phases. The greatest numbers of helicopter accidents were associated with landing (57%), manoeuveringFootnote 5 (29%), takeoff (21%), and en route and approach (18% each) phases of flight. The figures below show the distribution of accidents per phase of flight for the period 2007-2016.

From 2007 to 2016, of the 1166 aeroplane accidents with landing phase events, 21% involved collision with object, 21% involved missing or going off the runway, 21% involved landing gear collapse or retraction, and 19% involved a nosedown or overturning event. Of the 477 aeroplane accidents with take-off phase events, 28% involved collision with terrain, 28% involved collision with object, 26% involved loss of control, and 26% involved power loss.
Collision with terrain was the predominant event in fatal aeroplane accidents from 2007 to 2016. Collision with terrain was involved in 57% of the 49 fatal aeroplane accidents with takeoff phase events, 69% of 77 fatal aeroplane accidents with en route phase events, 77% of 26 fatal aeroplane accidents with manoeuvering phase events, 70% of 47 fatal aeroplane accidents with approach phase events, and 54% of 35 fatal aeroplane accidents with landing phase events.
From 2007 to 2016, of the 141 helicopter accidents with landing phase events, 26% involved a collision with object, 21% involved a hard landing, 21% involved collision with terrain, and 19% involved loss of control. Of the 84 helicopter accidents with manoeuvering phase events, 49% involved collision with terrain, 33% involved loss of control, and 24% involvedoperations related event.
Collision with terrain was also the predominant event in fatal helicopter accidents from 2007 to 2016. Collision with terrain was involved in 6 of 8 fatal helicopter accidents with takeoff phase events, 17 of 23 fatal helicopter accidents with en route phase events, 12 of 19 fatal helicopter accidents with manoeuvering phase events, 3 of 7 fatal helicopter accidents with approach phase events, and 6 of 8 fatal helicopter accidents with landing phase events.
Overview of Incidents
Pursuant to TSB mandatory incident reporting requirements, 833 incidents were reported in 2016, with 737 involving Canadian-registered aircraft. This is a 4% increase from the 2015 total of 711, a 21% increase from the 5-year average of 610, and a 14% increase from the 10-year average of 645. On March 12, 2014, the TSB issued new regulations that changed the reporting requirements effective July 1, 2014. Under the new reporting requirements aviation incidents include aircraft having a maximum certificated take-off weight greater than 2 250 kg (formerly 5700 kg) and aircraft being operated under an air operator certificate issued under CARS Part VII.
In 2016, the most frequent incident types involving all Canadian-registered and foreign-registered aircraft were declared emergency (37%), risk of collision or loss of separation, (17%), and engine failure (13%) (Figure 7).
