Fatal Accidents by Phase of Flight

A majority of the total HAA accidents in 2010-2015 (74%) and 2016-2021 (69%) were associated with the cruise or landing phase of flight. In 2010-2015, there were 4/47 (9%) fatal HAA accidents during landing, 2/47 (4%) during takeoffs, and 1/47 (2%) during hover and ground. In 2016-2021, there were 2/36 (6%) fatal accidents during landing and 0 during takeoffs or hover and ground. There was no statistically significant reduction (P > .05) in landing, takeoff, or hover and ground fatal accidents. However, during cruise, there was a statistically significant reduction (P < .05) in the proportion of fatal HAA accidents in 2016-2021 (with 4/36 (11%) being fatal) from 2010-2015 (with 14/47 (30%) being fatal).


Discussion

This article studied 83 HAA accidents in the United States to better understand and compare the numbers, proportions, contributing or causal factors, and defining events of HAA accidents between 2010-2015 and 2016-2021 as collected from the NTSB final investigation reports and summary data. The major results of this study are as follows:

1.

There was a significant decrease in the proportion of fatal HAA accidents from 2010-2015 (21/47 [45%] being fatal) to 2016-2021 (6/36 [17%] being fatal).

2.

The fatal HAA accident rate per 100,000 FHs appeared to be decreasing between 2010 and 2021, with 0 fatal HAA accidents recorded in 2018, 2020, and 2021.

3.

There was a statistically significant reduction in the proportion of nighttime fatal HAA accidents from 2010-2015 (with 15/47 [32%] being fatal) to 2016-2021 (with 3/36 [8%] being fatal).

4.

From the collected 83 HAA accident data, more than half of the total HAA accidents in 2010-2015 (57%) and 2016-2021 (53%) were associated with pilots with less than or equal to 500 FHs in the aircraft make and model involved in the accident.

5.

Of the fatal HAA accidents, 62% (13/21) in 2010-2015 and 67% (4/6) in 2016-2021 were associated with pilots with less than or equal to 500 FHs in the aircraft make and model involved in the accident.

6.

There was a significant decrease in the HAA accidents associated with VFR encounter IMC events from 2010-2015 (19%) to 2016-2021 (3%).

7.

There was a significant decrease in the fatal HAA accidents associated with the cruise phase of flight from 2010-2015 (30%) to 2016-2021 (11%).

8.

Landing, hover and ground, and takeoff accounted for a majority of the HAA accidents in 2010-2015 (53%) and 2016-2021 (72%).


Conclusions

Further research is needed to understand the root causes and/or contributing factors to HAA accidents and to study the number of accidents per number of HAA operations.
